A strong semi truck shock choice matches the truck or suspension position precisely and provides the dimensions and mounting style your replacement requires. For a broad range of Kenworth and Peterbilt front applications, Gabriel 85989 FleetLine is a leading option; drivers seeking adjustable front ride settings can consider Gabriel 89408 GasSLX. The products here also cover trailer suspensions, Mack and Volvo trucks, and cab-shock replacements for Freightliner and other models.
Fitment matters more than brand alone: shocks that look similar can have different extended and collapsed lengths, mounting codes, or vehicle coverage. Use the listed model years and interchange numbers as a starting point, then confirm the existing shock and vehicle configuration before ordering.
This roundup compares the product data supplied, not independent performance testing.
Gabriel 85989 FleetLine is the best overall choice in this group for many semi truck front-shock replacements because its listed fitment spans numerous Kenworth T-series models and Peterbilt 330, 337, 348, 567 and 579 trucks. It is a heavy-duty front shock with a broad stated vehicle range, making it a practical starting point for buyers whose truck matches the listed applications. For different needs, the list also includes adjustable settings, trailer-specific shocks and dedicated cab shocks; confirm exact fitment before choosing.

Detailed Reviews: Best Semi Truck Shocks
#1 · Best Overall
1. Gabriel 85989 FleetLine
- Material Type: Metal
- Compatible with Vehicle Type: Bus, RV, Truck, Van
- Weight: 8.3 lb
Best for: Kenworth and Peterbilt front fitment.
Why it ranks #1: Its listed front fitment spans many Kenworth T-series trucks and Peterbilt models including the 330, 348, 567 and 579.
Fitment across numerous Kenworth and Peterbilt models, including T680, T880, 567, and 579, is the central strength of this Gabriel FleetLine front shock. The listing also calls out specific ICON 900 spring and axle conditions, giving parts buyers important application detail beyond a model name alone.
Gabriel lists applications across Kenworth ICON 900, T270, T280, T370, T380, T480, T680, and T880 models, as well as Peterbilt 330, 337, 348, 536, 537, 548, 567, and 579. For ICON 900, the listing narrows fitment to models with 10,000–14,600-pound Taperleaf springs and set-back front axles. That added condition helps buyers screen the front suspension configuration, while the broad model list aids fleet parts lookup.
- Lists multiple Kenworth and Peterbilt model applications
- Specifies front-shock use
- Provides ICON 900 spring and axle conditions
- Lists OEM references B71-6019 and B71-6020
- The listing does not provide extended, collapsed, or stroke measurements.
Skip it if you require published shock travel dimensions for your Peterbilt; Torque TR85033 lists extended length, collapsed length, and stroke.
Parts teams maintaining listed Kenworth or Peterbilt front suspensions can use the extensive model coverage to identify a candidate, with the ICON 900 conditions especially relevant. Match the truck configuration carefully; travel dimensions are not supplied.

2. Gabriel 89408 GasSLX
- Material Type: Metal
- Compatible with Vehicle Type: Bus, RV, Truck, Van
- Weight: 3.22 kg
Best for: Adjustable heavy-duty front shock.
Why it ranks #2: Three settings—Firm, Regular and Extra Firm—let compatible Peterbilt and Kenworth owners choose among stated ride-control adjustments.
Three selectable settings—Firm, Regular, and Extra Firm—let operators tailor ride control to their preference or load conditions. Gabriel lists this GasSLX adjustable front shock for selected Peterbilt trucks and Kenworth T880 and W900 models, pairing adjustment flexibility with OE-style mounts for supported commercial applications.
The three-position adjustment is the central practical feature: Firm, Regular, and Extra Firm provide defined choices for ride control rather than a single fixed setting. Gabriel also states that the design improves stability and reduces sway under heavy loads, connecting the adjustment feature to commercial-road use. OE-style mounts support a replacement workflow, and the corrosion-resistant finish is relevant for demanding road and weather conditions. The listed fitment names selected Peterbilt models and Kenworth T880 and W900, so application matching remains essential.
- Offers Firm, Regular, and Extra Firm settings
- Lists selected Peterbilt and Kenworth fitment
- OE-style mounts support replacement installation
- Corrosion-resistant finish is specified
- The listing does not provide extended, collapsed, or stroke measurements.
Skip it if you want published shock travel dimensions before ordering; Gabriel 83081 provides extended length, collapsed length, and stroke specifications.
For operators of listed Peterbilt or Kenworth trucks who want selectable firmness, the GasSLX adjustment is the defining benefit. Its application list is specific, and buyers needing travel dimensions should note they are not supplied here.

3. Torque TR85066
- Material Type: Steel/Aluminum Alloy
- Compatible with Vehicle Type: Semi Trucks
- Weight: 4 lb
Best for: Mack and Volvo fleet replacement.
Why it ranks #3: Listed for Mack Anthem and multiple Mack and Volvo models, this shock provides a 9.41-inch stroke and 24.63-inch extended length.
A 9.41-inch stroke gives this Torque shock a longer listed travel range than many compact cab-shock options, while fitment spans selected Mack and Volvo models. Its 24.63-inch extended and 15.22-inch collapsed lengths let fleet maintainers compare mounting dimensions before choosing this four-shock replacement set.
The long extended length and 9.41-inch stroke provide useful travel measurements for the listed truck applications, while the 15.22-inch collapsed length helps buyers compare the compressed dimension with the space available at the mounting point. Torque specifically names Mack Anthem, CHN, CHU, CXN, CXP, CXU and several Volvo VN-series models. A dust tube and recoil cutoff are also listed, and rebound and compression figures give maintainers further specifications for evaluating the replacement.
- Lists fitment across selected Mack and Volvo models
- Provides extended, collapsed, and stroke measurements
- Includes a dust tube and recoil cutoff
- Lists rebound and compression figures
- The listed applications do not include Freightliner models.
Skip it if you maintain a Freightliner Cascadia cab; Gabriel 83038 lists Cascadia fitment and cab-shock dimensions.
This set suits fleet buyers replacing shocks on the named Mack or Volvo applications who can use its detailed travel measurements. Its fitment list is specific, so match the truck model and mounting position before selecting it.

View on Amazon#4 · Trailer Fit
4. Torque TR85000
- Material Type: Alloy Steel
- Compatible with Vehicle Type: Trailer,Trucks
Best for: Trailer suspension replacement set.
Why it ranks #4: Its stated compatibility includes Hendrickson, Ridewell and SAF Holland trailer suspensions, with 17.22-inch extended and 11.46-inch collapsed lengths.
A 5.76-inch stroke pairs with a 17.22-inch extended length and 11.46-inch collapsed length, giving buyers specific dimensions to compare against a trailer’s existing shock. Torque lists compatibility with systems including Hendrickson, Ridewell, SAF Holland, and Meritor, making this four-shock set a targeted replacement option for supported setups.
The listed extended and collapsed lengths help establish whether the shock’s travel range suits the intended mounting position, while its 1-5/8-inch bore and recoil cutoff add useful specification points for parts comparison. Torque names CUSH, Hendrickson, Ridewell, SAF Holland, Trailmobile Canada, Wabash, and Meritor among compatible systems, so fleet maintainers can assess it against those trailer applications. The four-unit listing suits buyers replacing several matching shocks together; its stated rebound and compression figures provide additional reference data.
- Lists fitment for Hendrickson, Ridewell, SAF Holland, and Meritor systems
- Provides extended, collapsed, and stroke measurements
- Includes a dust tube and recoil cutoff
- Lists rebound and compression figures
- Fitment is centered on listed trailer systems rather than a broad set of named truck models.
Skip it if you need a shock for a specific truck model not covered by the listed trailer-system fitment; Gabriel 85066 lists numerous Mack and Volvo models.
For trailer operators or parts buyers matching a shock to a listed CUSH, Hendrickson, Ridewell, SAF Holland, Trailmobile Canada, Wabash, or Meritor application, this set offers detailed dimensions; verify the intended system and travel requirements.

5. Gabriel 85000 FleetLine
- Material Type: Metal
- Compatible with Vehicle Type: Bus, RV, Truck, Van
Best for: Gabriel trailer suspension fitment.
Why it ranks #5: This commercial rear shock lists Hendrickson Intraax and Vantraax among broad trailer and bus applications, making its suspension focus clear.
Compatibility with Hendrickson Intraax and Vantraax trailer air suspensions is the key distinction of this Gabriel FleetLine shock, with additional listed applications covering trailer, bus, truck, and van equipment. Buyers maintaining mixed commercial fleets can use its broad compatibility list to identify potential replacement applications.
The product title calls out Hendrickson Intraax and Vantraax, while the fitment details name Cush, East Manufacturing, Great Dane, Ridewell, SAF Holland, Stoughton, and other commercial vehicle applications. That breadth helps parts teams compare one shock against multiple listed equipment types rather than relying on a passenger-car fitment description. Gabriel identifies it as a commercial fleet truck and trailer suspension shock, and the included-components field specifies one shock, useful when planning an individual replacement.
- Title specifies Hendrickson Intraax and Vantraax trailer air suspensions
- Lists compatibility with multiple trailer manufacturers and suspension systems
- Identified for commercial fleet truck and trailer suspension
- Included-components field specifies one shock
- The listing does not provide extended, collapsed, or stroke measurements.
Skip it if you need a shock with published travel dimensions for a Peterbilt front application; Torque TR85033 lists extended length, collapsed length, and stroke.
A fleet parts buyer handling the named trailer suspension systems, buses, or other listed commercial applications may find this Gabriel option relevant. Check the specific equipment application, since the supplied listing provides fitment names but no travel dimensions.

6. Torque TR85033
- Material Type: Steel/Alloy Steel
- Compatible with Vehicle Type: Truck
Best for: Peterbilt multi-model replacement set.
Why it ranks #6: Its Peterbilt fitment covers numerous models and its listed dimensions—27.26 inches extended and 17.4 inches collapsed—help identify the application.
Peterbilt fitment spanning model years from 1981 through 2016 gives this Torque four-shock set unusually broad coverage across the listed 330, 357, 362, 372, 375, 376, 377, 378, 379, 384, 385, 386, 387, and 587 trucks. Detailed mounting and travel measurements support parts matching.
Torque specifies 27.26 inches extended, 17.4 inches collapsed, and 9.86 inches of stroke, letting maintainers compare the shock’s travel with the existing installation. The upper stud mount and lower bushings for a one-inch mounting bolt provide concrete mounting details for a parts check. Its long Peterbilt model list covers several generations, while Gabriel 85033 and 03-06084P are listed as replacement references. This combination can help fleet teams identify a candidate from either vehicle or interchange records.
- Lists fitment across numerous Peterbilt models
- Provides extended, collapsed, and stroke measurements
- Specifies upper stud and lower bushing mounts
- Lists Gabriel 85033 and 03-06084P replacement references
- The listed vehicle fitment is limited to Peterbilt models.
Skip it if you need a shock for a Freightliner or Volvo application; Torque TR85066 lists selected models from both truck brands.
Peterbilt fleet maintainers matching one of the listed models can use the broad application range, mounting details, and interchange numbers to assess this set. Its vehicle coverage is Peterbilt-focused, so other makes require a different application listing.

7. Bulldog HD1214-0845
- Material Type: Metal
- Compatible with Vehicle Type: Truck
Best for: Cascadia front suspension replacement.
Why it ranks #7: A focused front-shock listing for Freightliner Cascadia models from 2017–2022, with Monroe 66458 and Gabriel 83396 replacement references.
Nitrogen gas charging is the stated distinguishing feature of this Bulldog HD front suspension shock, and its title specifies Freightliner Cascadia fitment for 2017–2022. The listing also identifies Monroe 66458 and Gabriel 83396 as replacement references, helping parts buyers connect the shock to those existing numbers.
This shock is explicitly described as a nitrogen gas-charged front suspension part for Freightliner Cascadia trucks from 2017 through 2022, giving buyers a model and year range to use when screening applications. The listed Monroe 66458 and Gabriel 83396 replacement references offer another route for matching an existing part. Its supplied information does not provide travel measurements or adjustment settings, so buyers comparing mounting dimensions will need details beyond those included in this listing.
- Specifies Freightliner Cascadia fitment for 2017–2022

- Nitrogen gas charging is stated in the title
- Lists Monroe 66458 and Gabriel 83396 replacement references

8. Gabriel 83081 FleetLine
- Material Type: Metal
- Compatible with Vehicle Type: Bus, RV, Truck, Van
Best for: Kenworth and Peterbilt cab fitment.
Why it ranks #8: A dedicated cab-shock fit for several Kenworth and Peterbilt models, with listed dimensions of 13.39 inches extended and 9.98 inches collapsed.
A four-inch stroke distinguishes this Gabriel FleetLine cab shock, with fitment listed for Kenworth T680, T880, and W990 models and several Peterbilt trucks. Its 13.39-inch extended and 9.98-inch collapsed dimensions give maintainers concrete measurements for a cab-shock replacement comparison.
The 13.39-inch extended length, 9.98-inch collapsed length, and four-inch stroke help buyers assess the shock’s travel against the cab mounting position. Gabriel lists model-year applications for Kenworth T680, T880, and W990, alongside Peterbilt 348, 567, and 579, among others. The stated focus on reducing vibration and cab movement connects those dimensions to driver comfort, while OEM-style fit is described as supporting replacement. Upper and lower mount codes further assist parts identification.
- Lists Kenworth and Peterbilt cab-shock applications
- Provides extended, collapsed, and stroke dimensions
- Specifies upper and lower mount codes
- Described as reducing cab vibration and movement
- The listing specifies one shock rather than a multi-shock set.
Skip it if you need a Freightliner Cascadia cab shock; Gabriel 83038 lists Cascadia among its applications and provides cab-shock dimensions.
For maintainers working on listed Kenworth or Peterbilt cabs, this Gabriel shock combines model coverage with travel and mount details. Its one-shock listing suits an individual replacement; verify the truck’s application and mounting position.

9. Gabriel 83038 FleetLine
- Material Type: Metal
- Compatible with Vehicle Type: Bus, RV, Truck, Van
- Weight: 1.55 kg
Best for: Freightliner cab comfort replacement.
Why it ranks #9: This cab shock lists Freightliner Cascadia, Columbia and other applications, with a 10.45-inch extended length and 8.41-inch collapsed length.
Gabriel links this FleetLine cab shock’s purpose to reduced vibration and cab movement, a practical focus for drivers covering long-haul routes. Its listed 10.45-inch extended length, 8.41-inch collapsed length, and Freightliner applications help parts buyers connect that comfort goal to a specific replacement fit.
The stated goal of reducing vibration and cab movement gives this shock a clear cab-focused role, while its heavy-duty construction and long-haul durability description address demanding fleet use. OEM-style fit is presented as support for an easier replacement process. Gabriel lists dimensions of 10.45 inches extended, 8.41 inches collapsed, and 3 inches of stroke, plus upper and lower mount codes. Those measurements help maintainers compare the shock with the cab mounting position on a listed Freightliner application.
- Described as reducing vibration and cab movement
- Lists Freightliner cab-shock applications
- Provides extended, collapsed, and stroke dimensions
- Specifies upper and lower mount codes
- The listing specifies one shock rather than a multi-shock set.
Skip it if you need a cab shock for a Kenworth T680; Gabriel 83081 lists T680 fitment with its own mounting codes and dimensions.
This is a focused choice for Freightliner operators prioritizing cab vibration control and maintainers who want dimensions and mount codes for comparison. It is listed as one shock, and its fitment should be matched to the truck.

10. ZANURA 83038 Cab Shock
- Material Type: Metal
- Compatible with Vehicle Type: Truck
- Weight: 6.3 lb
Best for: Multi-model Freightliner cab shock.
Why it ranks #10: It is a cab-shock replacement rather than a general suspension shock, although its fitment lists Freightliner trucks including Cascadia and 108SD.
A 10.45-inch extended length and 8.41-inch collapsed length give this two-pack Freightliner cab shock a clear dimensional profile. ZANURA lists applications ranging from Cascadia and Century Class to 108SD, 114SD, and M2 112, making its broad model coverage the main point for fleet parts matching.
The listed cab-shock dimensions establish a 2.04-inch difference between extended and collapsed lengths, a useful comparison when checking the intended mounting position. Its fitment spans several Freightliner lines and years, including Cascadia, Century Class, Columbia, Coronado, 108SD, 114SD, 122SD, and M2 112. The listing also supplies several interchange references, including Monroe 66122 and Freightliner numbers, which can help a buyer identify a replacement from existing parts records. Compatibility still depends on the exact truck application.
- Lists fitment across multiple Freightliner truck lines
- Provides extended and collapsed lengths
- Names Monroe and Freightliner interchange references
- Sold as a two-shock set
- The listed vehicle applications are Freightliner models.
Skip it if you need a Kenworth T680 or Peterbilt 579 cab shock; Gabriel 83081 lists those applications and its travel dimensions.
Freightliner fleet maintainers seeking cab shocks for one of the listed truck lines can use the model coverage and interchange references to narrow a replacement. Confirm the exact application and dimensions, since the fitment is Freightliner-specific.

View on AmazonWhy shock position and dimensions can trip up a replacement
A shock’s position and exact dimensions can make an otherwise plausible replacement the wrong part. These listings cover distinct jobs: Gabriel 85989 FleetLine is a front shock, Gabriel 83038 FleetLine and Gabriel 83081 FleetLine are cab shocks, and Gabriel 85000 FleetLine is a rear shock for trailer applications. Their sizes are not interchangeable by appearance: Gabriel 83038 FleetLine lists a 10.45-inch extended length and 8.41-inch collapsed length, while Gabriel 83081 FleetLine lists 13.39 and 9.98 inches.
Even the two cab-shock listings therefore have different dimensions. Check the mounting codes where supplied, along with extended and collapsed lengths, stroke, and the position being serviced.
A model name or a shared interchange reference is useful for narrowing choices, but does not establish that every trim, axle, or suspension configuration fits.
A cab shock is not a suspension shock
A cab shock is intended to address cab movement, not to replace a wheel-suspension shock. Gabriel describes its 83038 and 83081 FleetLine products as cab shocks intended to reduce vibration and cab movement, while the other listed products identify front, rear, trailer, or general truck applications. This distinction matters when diagnosing a rough ride: cab movement and wheel or axle control involve different positions and applications, so buying by truck make alone can send you to the wrong category.
The listings also show a trade-off in application breadth: Gabriel 83038 FleetLine names several Freightliner models, while Gabriel 83081 FleetLine targets selected Kenworth and Peterbilt models. Neither listing provides comparative test results, so do not infer that one is universally smoother or more durable.
First identify the component position and the vehicle’s exact application, then compare dimensions and replacement numbers.
How to Choose Semi Truck Shocks
Vehicle and suspension fitment
Start with the exact truck, model year, and shock position, then match the listed application. Gabriel 85989 FleetLine names Kenworth T680 and T880 as well as Peterbilt 567 and 579; Torque TR85066 lists selected Mack models and Volvo VN, VNL, VNM, VNR and VNX. Trailer buyers should distinguish Torque TR85000, which lists Hendrickson, Ridewell and SAF Holland, from truck-front applications.
The broadest model list may suit owners whose vehicles are explicitly included, while a focused listing is more useful when its model and years match exactly. When your truck has a less common configuration, compare the original part number and mounting arrangement instead of relying on make alone.
Length, stroke and mounting details
Compare extended length, collapsed length, stroke and mount details against the shock being replaced whenever those values are available. Torque TR85000 lists 17.22 inches extended, 11.46 inches collapsed and 5.76 inches of stroke; Torque TR85066 lists 24.63, 15.22 and 9.41 inches. Torque TR85033 specifies a stud upper mount and bushings for a 1-inch mounting bolt.
Cab shocks are shorter in the supplied data: Gabriel 83038 FleetLine lists 10.45 inches extended and Gabriel 83081 FleetLine 13.39 inches. Buyers with an exact part match can use these figures to verify dimensions; anyone replacing a different application should not select a shock simply because its length seems close.
Shock type and intended ride adjustment
Choose a shock type that matches the intended position and the adjustment features you actually need. Gabriel 89408 GasSLX is the only listing here with three selectable settings: Firm, Regular and Extra Firm; it is listed for specified Peterbilt and Kenworth front applications. Torque TR85000 and TR85066 list recoil cutoff and dust tubes, while their data also provides rebound and compression figures: 1,019 and 219 pounds for TR85000, and 812 and 322 pounds for TR85066.
Those figures are product specifications, not proof of a better ride in every truck. Buyers who want selectable settings and have a compatible vehicle can consider GasSLX; buyers replacing a matching fixed application should prioritize fit and dimensions over feature comparisons.

For a compatible Kenworth or Peterbilt front application, start with Gabriel 85989 FleetLine, which has the broadest stated front-model coverage in this selection. If you want three firmness settings and your truck is listed, choose Gabriel 89408 GasSLX.

Frequently Asked Questions
How can I confirm whether a shock fits my truck’s front, rear, cab, or trailer position?
Confirm the vehicle’s exact make, model, year, and shock position, then compare them with the product’s stated applications and part number. Check dimensions and mounting details against the vehicle or existing shock, too. A similar-looking shock is not proof of fit; verify the complete configuration before ordering.
When should semi truck shocks be replaced in pairs or as a complete axle set?
Replace shocks in matched pairs on the same axle when one has failed or shows wear, so damping remains consistent from side to side. Consider a complete axle set when multiple shocks are worn or their condition is uncertain. Follow vehicle and component guidance for the specific application.
What symptoms can indicate worn shocks rather than a tire or suspension problem?
Excessive bouncing, repeated oscillation after bumps, or reduced vehicle stability can point to worn shocks, but these signs are not conclusive. Tire condition, alignment, and other suspension parts can produce similar symptoms. Inspect the full system and have a qualified technician diagnose the cause before replacing components.
What should I check before choosing an adjustable shock?
First confirm that the exact truck and shock position are listed for the part; adjustable settings do not establish fitment. The Gabriel 89408 title identifies three firmness settings and lists specific Peterbilt and Kenworth applications. Check the complete application and determine whether those settings suit your operating needs.
Can a cab shock replace a front or rear suspension shock?
No; choose a shock for the intended position. The listed Gabriel 83038 and 83081 products are cab shocks, while other options specify front, rear, or trailer applications. Verify the part number, position, dimensions, and mounting for your truck before ordering rather than relying on the vehicle name alone.
Final Words
For a compatible Kenworth or Peterbilt front application, Gabriel 85989 FleetLine is the practical starting point here because its listed coverage spans numerous models. Choose by exact application, not by a broad product label: Gabriel 89408 offers adjustable settings, while the list also includes trailer and cab-specific options. Compare the part number, shock position, dimensions, and mounting with your vehicle configuration before ordering.
