A strong 4-inch leveling setup should deliver the intended front lift, match your truck’s exact year and suspension, and include the parts needed for its design. ReadyLift 69-1040 and ReadyLIFT 69-39400 are the closest matches here, with 4 inches of front lift and specific Dodge Ram or Chevy/GMC 1500 fitment. Rough Country’s F-150 kit also offers a 4-inch lift, with M1 struts, rear shocks, control arms, and knuckles.
Other listings provide different heights, cover different truck generations, or lift only the rear, so they are not interchangeable alternatives. Use the vehicle-specific fitment and front-versus-rear lift figures below to narrow your choice, then confirm suspension type, tire clearance, and installation requirements before ordering.
ReadyLIFT 69-39400 is the Best Overall choice for a 4-inch front lift on compatible Chevy Silverado and GMC Sierra 1500 models. It lists a 4-inch front and 3-inch rear lift, fitment for the stated model years, and installation without cutting or modifications. It also specifies tire-fitment examples up to 20×9 wheels with particular tire sizes.
Choose it only if your truck matches the listed fitment; Ram and Ford owners should consider the vehicle-specific alternatives instead.

Detailed Reviews: Best 4 In Leveling Kit

#1 · Best Overall
1. ReadyLIFT 69-39400
- Material: Alloy Steel, Aluminum, Cast Iron
- Material Type: Alloy Steel, Aluminum, Cast Iron
Best for: ARC Silverado and Sierra owners.
Why it ranks #1: Lists 4 inches of front and 3 inches of rear lift for compatible Chevy/GMC 1500 models, with no cutting or modifications required for installation.
A four-inch front lift paired with a three-inch rear lift gives this ReadyLIFT kit a clearly defined stance change for 2019–2023 Silverado and Sierra 1500 trucks. Its stated compatibility with Adaptive Ride Control Suspension makes it relevant to ARC-equipped trucks as well as non-ARC models, while the installation requires no cutting or modifications.
The kit’s four-inch front and three-inch rear lift changes both ends of the truck, rather than addressing only front height. ReadyLIFT lists fitment for 2019–2023 Silverado and Sierra 1500 models and says installation requires no cutting or modifications, which helps keep the installation plan focused on a bolt-on-style suspension change. Tire capacity is also specified: qualifying Chevy models accommodate up to 20×9 wheels with 295/65 R20 tires, while listed GMC and 2023 Chevy models use 295/55R20 tires.
- Provides a four-inch front and three-inch rear lift
- Listed for 2019–2023 Chevrolet Silverado and GMC Sierra 1500
- Compatible with ARC and non-ARC trucks according to the description
- Installation requires no cutting or modifications
- Excludes Trail Boss and AT4 models.
Skip it if you own a Trail Boss or AT4, which the listing excludes; choose a kit specifically listed for your trim instead.
This suits Silverado and Sierra 1500 owners seeking a substantial front-and-rear lift with stated ARC compatibility. Check the listed model years, trim exclusions, and tire specifications before choosing it for a particular truck.

#2 · Best Ram Fit
2. ReadyLift 69-1040
- Material: Aluminum
- Material Type: Aluminum
Best for: Dodge Ram 1500 4WD tire clearance.
Why it ranks #2: Provides a 4-inch front and 2-inch rear lift for specified Ram 1500 4WD trucks and includes tubular upper control arms; it excludes factory air suspension.
A four-inch front and two-inch rear lift paired with tubular upper control arms defines this ReadyLift SST kit for 2009–2017 Dodge Ram 1500 4WD trucks. The listing also specifies capacity for tires up to 35×12.50, making tire size a concrete part of its appeal for owners planning a taller setup.
The four-inch front and two-inch rear lift changes both ends of the truck, while the included tubular upper control arms add a named suspension component to the package. ReadyLift lists compatibility with 2009–2017 Ram 1500 4WD trucks and allows tires up to 35×12.50, helping buyers assess the intended fit and tire-clearance target together. The major boundary is suspension type: the kit is expressly not for trucks with factory air suspension, so that equipment must be checked before selecting it.
- Provides four inches of front lift and two inches of rear lift
- Includes tubular upper control arms
- Allows tires up to 35×12.50
- Listed for 2009–2017 Dodge Ram 1500 4WD trucks
- Not compatible with factory air suspension.
Skip it if you have factory air suspension; the listing excludes it, while the ReadyLIFT 69-39400 is for specified Silverado and Sierra models.
This fits owners of 2009–2017 Dodge Ram 1500 4WD trucks seeking a two-end lift and capacity for tires up to 35×12.50. Factory air suspension is a firm exclusion.

#3 · Best F-150 Kit
3. Rough Country 4-Inch F-150 Kit
- Material: Alloy Steel, Aluminum, Rubber, Zinc
- Material Type: Alloy Steel, Aluminum, Rubber, Zinc
Best for: 2021–2024 F-150 4WD cab owners.
Why it ranks #3: Specifies a 4-inch lift for later-generation F-150 4WD extended and crew cabs, with M1 struts, rear shocks, aluminum knuckles, and upper control arms.
M1 monotube struts and rear shocks give this Rough Country kit a complete damper package alongside its four-inch lift for 2021–2024 Ford F-150 4WD extended and crew cabs. Forged aluminum upper control arms and aluminum knuckles add specified suspension components, while the package targets a lifted stance and increased ground clearance.
The included M1 monotube struts and shocks provide front and rear damping components as part of the lift package, rather than leaving those items outside the listed bundle. Forged aluminum upper control arms and high-strength aluminum knuckles are specified to reduce vehicle weight and support suspension strength. The four-inch lift and front-and-rear leveling are presented as a way to increase ground clearance and create a more aggressive stance. Fitment is specifically stated for 4WD extended and crew cab F-150s from 2021 through 2024.
- Four-inch lift with front and rear leveling
- Includes M1 monotube struts and rear shocks
- Features forged aluminum upper control arms
- Includes high-strength aluminum knuckles
- Listed only for 2021–2024 F-150 4WD extended and crew cabs.
Skip it if you drive a 2WD F-150 or have a regular cab; the listed fitment is for 4WD extended and crew cab models.
This suits owners of 2021–2024 F-150 4WD extended or crew cabs seeking a four-inch lift with struts, shocks, control arms, and knuckles included. The stated cab and drivetrain fitment is narrow.

#4 · Best Older F-150 Fit
4. KSP F-150 Leveling Kit
- Material: Polyurethane (PU)
- Material Type: Polyurethane (PU)
Best for: F-150 owners needing year-specific lift.
Why it ranks #4: Covers 2004–2020 F-150 models with a 3-inch front lift and variable rear lift; its stock-wheel ET44 setup may rub the control arms.
A single kit covers 2004–2020 Ford F-150 2WD and 4WD applications, but its rear lift varies by drivetrain and model year. The KSP package pairs upper control arms rated for a two-to-four-inch lift with a three-inch front lift, giving buyers a bundled suspension change while making year-specific rear-height details important.
KSP specifies a three-inch front lift across the listed F-150 range, while rear results vary: 2WD models receive two inches, 2004–2008 4WD models retain factory rear height, and 2009–2020 4WD models gain 0.5 inch. That breakdown helps buyers set realistic expectations for stance before installation. The upper control arms support a two-to-four-inch lift, but the listing warns that stock ET44 wheels may rub; it recommends at least 1.5-inch wheel spacers or aftermarket wheels with zero offset.
- Listed for 2004–2020 F-150 2WD and 4WD
- Provides a three-inch front lift
- Upper control arms support a two-to-four-inch lift
- Lists different rear-height outcomes by drivetrain and model year
- Stock wheels with ET44 offset may rub against the control arms.
Skip it if you plan to retain stock ET44 wheels without spacers; the listing recommends 1.5-inch spacers or zero-offset aftermarket wheels.
This suits F-150 owners who can match the lift details to their year and drivetrain and account for wheel offset. The rear lift is not uniform, and stock ET44 wheels may rub.

5. Aeagle Silverado 2019–2022 Kit
- Material: Alloy Steel, Carbon Steel
- Material Type: Alloy Steel, Carbon Steel
Best for: Adjustable 2019–2022 GM 1500 setup.
Why it ranks #5: Combines 3 inches of front and 2 inches of rear lift with adjustable upper control arms for specified Silverado and Sierra 1500 models.
Adjustable upper control arms rated for a two-to-four-inch lift distinguish this Aeagle kit from a spacer-only leveling package. It combines those arms with three-inch front and two-inch rear lifts for 2019–2022 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, giving buyers a bundled approach to changing suspension height at both ends.
The package includes two front upper control arms with ball joints and replacement control-arm ball joints, alongside the front and rear lift components. That combination brings several suspension pieces together for installation rather than requiring the buyer to source those listed parts separately. The stated three-inch front and two-inch rear lift establishes the intended stance change, while the surface anti-corrosion coating is specified to help resist rust over time. Fitment is limited to the listed 2019–2022 GM 1500 applications.
- Upper control arms are adjustable for a two-to-four-inch lift
- Includes front control arms with ball joints
- Includes three-inch front and two-inch rear lift components
- Surface coating is specified to help prevent rust
- Fitment is limited to 2019–2022 Silverado 1500 and Sierra 1500 models.
Skip it if you have a 2007–2014 Silverado or 2007–2018 Sierra; the Aeagle AECLK003-S003 covers those older model-year ranges.
This package fits owners of listed 2019–2022 Silverado 1500 or Sierra 1500 trucks who want upper control arms and front-and-rear lift parts together. Its stated vehicle-year range is the key fit boundary.

6. Aeagle Silverado 2007–2014 Kit
- Material: Alloy Steel
- Material Type: Alloy Steel
Best for: Older Silverado and Sierra suspension refresh.
Why it ranks #6: Offers 3 inches front and 2 inches rear with upper control arms, but fitment is limited to specified older Chevy and GMC 1500 generations.
Replacement ball joints arrive with adjustable upper control arms in this Aeagle kit for older GM 1500 trucks. It specifies a three-inch front and two-inch rear lift for 2007–2014 Silverado 1500 and 2007–2018 Sierra 1500 applications, while its tire-width caveat makes wheel setup an important part of the decision.
This package combines two front upper control arms with ball joints, two replacement control-arm ball joints, and front and rear leveling components. The three-inch front and two-inch rear lift gives the listed older trucks a defined stance change, while the adjustable arms are specified for a two-to-four-inch lift. Aeagle also lists an anti-corrosion surface coating to help prevent rust. The fit notes say 275mm and 285mm-wide tires require wheel spacers, a practical constraint to resolve before installation.
- Listed for 2007–2014 Silverado 1500 models
- Listed for 2007–2018 Sierra 1500 models
- Includes adjustable upper control arms and replacement ball joints
- Includes three-inch front and two-inch rear lift components
- 275mm and 285mm-wide tires require wheel spacers for use.
Skip it if you run 275mm or 285mm-wide tires and do not plan to install wheel spacers; the listing flags that requirement.
This suits owners of the specified older Silverado and Sierra 1500 years who want control arms, replacement ball joints, and a two-end lift package. Tire width matters: listed 275mm and 285mm tires require spacers.

7. MZS 3.5-Inch Leveling Kit
- Material: Aluminum
- Material Type: Aluminum
Best for: Front-only Silverado and Sierra lift.
Why it ranks #7: Raises the front by a stated 3.5 inches using two spacer sizes, but excludes 2007 Classic, Trail Boss, and AT4 models.
A two-inch upper and 1.5-inch lower spacer combination produces a stated true 3.5-inch front lift on this MZS kit. It focuses on the front rather than offering a rear lift, giving eligible Silverado and Sierra owners a direct way to raise the front while the included aluminum spacers keep the package components clearly defined.
MZS says the combined two-inch upper and 1.5-inch lower spacers raise the truck’s front by 3.5 inches, while cautioning that spacer thickness does not translate one-to-one into lift height. The package includes two spacers of each listed size, installation hardware, and a guide, so buyers have the specified components and instructions together. Fitment excludes 2007 Classic, Trail Boss, and AT4 models. The front-only focus means this is not a complete front-and-rear leveling package.
- Provides a stated 3.5-inch front lift
- Combines two-inch upper and 1.5-inch lower spacers
- Aluminum spacer material is specified
- Includes installation hardware and a guide
- Does not include a rear lift component.
Skip it if you need a matched front-and-rear lift; ReadyLIFT 69-39400 lists four inches front and three inches rear for eligible GM 1500 trucks.
This suits Silverado and Sierra owners seeking a front-only height change using the listed spacer combination. Check the model-specific exclusions, especially 2007 Classic, Trail Boss, and AT4, before choosing it.

8. SCITOO Super Duty Kit
- Material: Iron
- Material Type: Iron
Best for: Super Duty front and rear lift.
Why it ranks #8: Fits specified F-250 and F-350 models and lists 3 inches of front lift with a 3-inch rear lift, rather than a 4-inch front lift.
A stated three-inch front and three-inch rear lift makes this SCITOO kit a two-end option for 2005–2022 Ford F-250 and F-350 Super Duty trucks. Its front spacer setup is described as adjustable from two to four inches, giving buyers a specified range to consider alongside the listed rear height.
SCITOO lists fitment for 2005–2022 F-250 and F-350 Super Duty models and describes a three-inch front lift with two-to-four-inch front adjustment, plus a three-inch rear lift. The listing cautions that spacer thickness is less than the resulting lift amount, so the spacer’s physical thickness should not be mistaken for the raised height. Strut spacers are the included components, making this a spacer-based package for buyers planning a front-and-rear change on the specified trucks.
- Listed for 2005–2022 Ford F-250 Super Duty
- Listed for 2005–2022 Ford F-350 Super Duty
- Specifies a three-inch rear lift
- Describes two-to-four-inch front adjustment and a three-inch front lift
- The listing notes that spacer thickness is less than the resulting lift height.
Skip it if you need a lift for a model year outside 2005–2022; the stated F-250 and F-350 Super Duty range does not cover it.
This suits F-250 and F-350 Super Duty owners within the listed 2005–2022 years seeking front and rear height changes using strut spacers. Note the stated lift height differs from spacer thickness.

View on AmazonWhy it ranks #9: Its description specifies up to 2 inches of front lift for GM HD trucks, below the target height, and excludes AT4X and ZR2 models with DSSV shocks.
FOX Hydraulic Top Out technology is the defining ride feature of this Kryptonite Stage 4 kit, which levels the front of a GM HD truck by up to two inches. Its torsion keys are listed as 25% stronger than OEM, connecting the height adjustment with a specified torsion-bar component for owners considering larger tires.
The adjustable torsion key allows a front lift of up to two inches, while the description says the kit prevents shock failure beyond that lift. FOX Hydraulic Top Out technology is identified as the ride feature intended to maintain a smooth, comfortable ride with larger tires. Together, these details make the package relevant to GM HD owners seeking a modest front-leveling change rather than a four-inch lift. The listing specifically excludes AT4X and ZR2 trucks equipped with DSSV shocks.
- Levels the front of a GM HD truck by up to two inches
- Torsion keys are stated to be 25% stronger than OEM
- Uses FOX Hydraulic Top Out technology
- Description links the HTO feature to comfort with larger tires
- Incompatible with AT4X and ZR2 trucks featuring DSSV shocks.
Skip it if you have an AT4X or ZR2 with DSSV shocks; this kit is explicitly incompatible with those trucks.
This is for GM HD owners seeking up to two inches of front leveling and the listed FOX HTO feature. Its stated fit boundary excludes AT4X and ZR2 trucks with DSSV shocks.

View on AmazonWhy it ranks #10: Provides a 4-inch rear-only lift for specified Silverado and Sierra 1500 models, so it does not deliver the front leveling lift most shoppers seek.
Four inches of rear lift is the sole height change specified for this Psrorkeu kit, aimed at 2007–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks in 2WD or 4WD. Its rear blocks and extended U-bolts make the package a focused option for owners addressing rear suspension height rather than both ends.
The kit includes two heavy-duty rear lift blocks and four extended U-bolts, plus the necessary mounting hardware, for installation on the rear left and right sides. Those components support the listed four-inch rear suspension lift and its ground-clearance and leveled-stance goals. Because the product is explicitly rear-only, it does not provide a front lift; buyers seeking a coordinated change at both ends should account for that scope. Fitment is stated for 2007–2018 Silverado and Sierra 1500 models, including 2WD and 4WD.
- Provides a specified four-inch rear suspension lift
- Includes two rear lift blocks
- Includes four extended U-bolts and mounting hardware
- Listed for 2007–2018 Silverado and Sierra 1500 in 2WD and 4WD
- Raises the rear only; no front lift is specified.
Skip it if you want a front-and-rear lift; Aeagle AECLK003-S003 lists three inches front and two inches rear for older GM 1500 trucks.
This is for 2007–2018 Silverado and Sierra 1500 owners who specifically need a four-inch rear lift. Its blocks-and-U-bolts package addresses the rear only, not a matched front-and-rear stance.

Listed on Amazon as: 4-Inch Rear Suspension Leveling Lift Kit with Blocks and U-Bolts
View on AmazonWhy front and rear lift numbers matter
A kit’s stated lift is not always a single, even height across the truck, so compare front and rear figures separately. ReadyLIFT 69-39400 lists 4 inches in front and 3 inches in the rear, while ReadyLift 69-1040 lists 4 inches front and 2 inches rear. Rough Country 4-Inch F-150 Kit describes a 4-inch lift with front and rear leveling, whereas Psrorkeu Rear Lift Kit raises only the rear by 4 inches.
Those differences affect stance and mean the rear-only product is not a substitute for a front leveling kit. Some listings also warn that spacer thickness does not equal the resulting lift: MZS 3.5-Inch Leveling Kit and SCITOO Super Duty Kit both note that their spacer thickness is less than the stated lift amount.
Use the listed vehicle lift height—not spacer thickness alone—to compare expected changes, and confirm whether the kit’s front/rear balance suits your truck.
Fitment and tire-clearance traps
The most common compatibility trap is treating a model name as enough to confirm fitment. ReadyLIFT 69-39400 excludes Trail Boss and AT4, while Kryptonite Stage 4 Kit excludes AT4X and ZR2 trucks with DSSV shocks. ReadyLift 69-1040 is for Ram 1500 4WD and is not for trucks with factory air suspension.
Tire and wheel combinations matter too: ReadyLIFT 69-39400 gives specific wheel-and-tire examples, Aeagle Silverado 2007–2014 Kit cautions against 275mm or 285mm tires without wheel spacers, and KSP F-150 Leveling Kit warns stock ET44 wheels may rub the control arms. These are product-specific limits, not universal rules for every kit.
Before buying, check the exact year, trim, drivetrain, suspension, wheel offset, and tire size against the listing and manufacturer fitment information.
How to Choose a 4-Inch Leveling Kit
Front and rear lift height
Look for separate front and rear lift figures, not just the headline height. ReadyLIFT 69-39400 lists 4 inches front and 3 inches rear; ReadyLift 69-1040 lists 4 inches front and 2 inches rear. Rough Country 4-Inch F-150 Kit specifies a 4-inch lift, while several alternatives list 3 inches front and 2 inches rear.
MZS 3.5-Inch Leveling Kit raises the front by 3.5 inches, and Psrorkeu Rear Lift Kit adds 4 inches only at the rear. Buyers seeking a 4-inch front lift should focus on kits that state that figure explicitly.
Those prioritizing a smaller change or a particular front-to-rear stance may prefer the lower or split-height alternatives.
Exact vehicle and suspension fitment
Choose a kit only after matching its stated fitment to your truck’s generation, drivetrain, trim, and suspension. ReadyLIFT 69-39400 lists Chevy and GMC 1500 models within its stated range but excludes Trail Boss and AT4. ReadyLift 69-1040 is for Ram 1500 4WD and excludes factory air suspension; Rough Country 4-Inch F-150 Kit is for specified F-150 4WD extended and crew cabs.
Other options cover earlier Silverado/Sierra or F-150 generations, while SCITOO Super Duty Kit lists F-250 and F-350 fitment. Buyers with a matching, explicitly listed vehicle can consider those dedicated kits; anyone with a trim or suspension variation should verify compatibility before ordering rather than relying on brand and model alone.
Included suspension parts
Check which components come with the lift, because kits with similar height claims can require different supporting parts. ReadyLift 69-1040 includes tubular upper control arms, and Rough Country 4-Inch F-150 Kit lists upper control arms, M1 struts, rear shocks, aluminum knuckles, and lift blocks. Aeagle Silverado 2019–2022 Kit includes adjustable upper control arms with ball joints and front and rear lift pieces.
By contrast, SCITOO Super Duty Kit lists strut spacers, while Psrorkeu Rear Lift Kit supplies rear blocks and extended U-bolts. Buyers seeking a more complete suspension-component package should compare the listed parts carefully; those considering a spacer- or block-focused kit should confirm what else their installation requires.
Product listings do not establish installation skill, alignment needs, or compatibility with unlisted components.
Which 4-Inch Leveling Kit Should You Choose?
For a compatible Chevy Silverado or GMC Sierra 1500, choose ReadyLIFT 69-39400: it specifies 4 inches front, 3 inches rear, and no cutting or modifications for installation. Ram 1500 4WD owners should look at ReadyLift 69-1040, provided the truck does not have factory air suspension. For a specified newer F-150 4WD extended or crew cab, Rough Country 4-Inch F-150 Kit is the dedicated 4-inch option and includes M1 struts, rear shocks, control arms, and knuckles.
If a 3-inch front lift suits your needs, compare the Aeagle kits by truck generation. Avoid treating Psrorkeu Rear Lift Kit as a front-leveling alternative: its 4-inch lift is rear-only.
Verify exact fitment and wheel clearance before choosing.

Frequently Asked Questions
How can I confirm whether a leveling kit fits my truck’s exact trim and suspension?
Check the kit’s stated year range, make, model, drivetrain, cab, trim exclusions, and suspension requirements against your truck. Confirm whether factory features such as air suspension affect compatibility. If any detail is unclear, verify the exact vehicle configuration with the kit manufacturer or a qualified installer before ordering.
Will a 4-inch lift require different wheels or tires to avoid rubbing?
Not necessarily; wheel and tire clearance depends on the vehicle and kit, not lift height alone. Check the kit’s stated fitment guidance for wheel dimensions, tire sizes, and any conditions, then compare it with your current setup. Confirm clearance before installation, since unsuitable combinations may rub during turns or suspension travel.
Does changing ride height affect alignment, handling, or suspension wear?
It can. Changing ride height may alter alignment angles and suspension geometry, so follow the kit’s installation guidance and have alignment checked afterward. Handling and component wear can also depend on fitment, installation, and driving conditions.
If steering feels different or components make unusual noises, have the truck inspected.
What should I check before choosing a kit for my truck?
Start with the exact vehicle fitment and the lift amount at the front and rear. Check whether the kit is front-only, rear-only, or includes both, and review its listed components and installation requirements. Match those details to your intended ride height and confirm wheel and tire clearance before purchase.
Can a rear-only lift kit level the front of my truck?
No. A rear-only kit raises the rear and does not provide a front lift, so it is not a substitute for a front-leveling kit. The listed 4-inch rear suspension kit is rear-only.
Confirm which end of the truck a kit lifts before choosing it for a particular stance or ride-height change.
Final Words
Choose by exact vehicle fitment and which end of the truck needs lifting, not by lift height alone. ReadyLIFT 69-39400 is the overall pick for compatible Silverado and Sierra 1500 models; Ram 1500 4WD owners can consider 69-1040 if their truck lacks factory air suspension. The Rough Country kit is the dedicated 4-inch option for its specified F-150 fitment.
Verify clearances and installation requirements before deciding.
