A strong 2-inch 8×170 spacer should match your vehicle’s hub bore and stud thread as well as its bolt pattern; this roundup suits Ford Super Duty and Excursion owners checking fitment before widening their stance. The listed options vary in hub-centric versus lug-centric design, M14x1.5 versus M14x2 threads, bore sizes, and whether they arrive as a pair or four-pack. Wheel Accessories Parts’ four-piece hub-centric set leads for shoppers seeking a full set with a stated 124.9mm hub bore and forged aluminum construction.
Other picks offer 12.9-grade studs, different vehicle-year ranges, or a two-piece package. Check your exact vehicle configuration—including single or dual rear wheels—and confirm measurements before ordering, because the products do not share one universal fitment specification.
Wheel Accessories Parts 4-Piece Hub-Centric is the strongest all-around pick because it combines a four-piece package, 2-inch thickness, 8×170 bolt pattern, 124.9mm hub dimensions, and a stated forged 6061-T6 aluminum build. It is listed for Ford Excursion and F-250/F-350 Super Duty applications. Confirm your exact vehicle and hub measurements first; other options specify different thread pitches, hub bores, or vehicle-year ranges, so the shared 8×170 pattern alone does not establish fit.

Detailed Reviews: Best 2 Inch Wheel Spacers 8X170

#1 · Best Overall
1. Wheel Accessories Parts Hub-Centric
- Weight: 28.7 lb
Best for: Four-wheel hub-centric setup.
Why it ranks #1: Four-piece hub-centric set specifies 2-inch thickness, 124.9mm hub dimensions, M14x1.5 threads, and forged 6061-T6 aluminum for listed Super Duty fitment.
Four 2-inch hub-centric spacers make this Wheel Accessories Parts set a practical match for buyers outfitting all four positions together. Its 124.9mm hub dimensions and 8x170mm pattern identify the intended interface, while the listed F-250 and F-350 fitments give the selection a clear Super Duty focus.
The set specifies 124.9mm vehicle-hub and wheel openings, connecting the hub and wheel sides through matching dimensions rather than a lug-centric design. Its 8x170mm vehicle and wheel patterns, plus M14x1.5 threads, define the bolt interface for listed Super Duty models. Forged 6060-T6 aluminum alloy and black anodizing are stated; the maker says anodizing enhances hardness and corrosion resistance. Four spacers provide a complete set for a four-position installation, subject to vehicle fitment.
- Four 2-inch spacers in the set
- Hub-centric 124.9mm openings on both sides
- 8x170mm pattern with M14x1.5 threads
- Forged aluminum alloy with black anodizing
- The listed thread pitch is M14x1.5, unlike 14×2 options.
Skip it if you need M14x2 studs; Wheel Accessories Parts' two-piece 8170-8170H-E142.2 listing specifies that thread pitch.
Choose this set if your listed Super Duty application needs four 2-inch hub-centric spacers with M14x1.5 threads. The 124.9mm hub dimensions and model coverage remain key fit boundaries to match before installation.

#2 · High-Grade Studs
2. YIZBAP Hub-Centric Spacers
- Weight: 12.93 lb
Best for: Hub-centric pair for F-Series.
Why it ranks #2: Two-piece hub-centric design lists a 124.9mm bore, M14x1.5 threads, and grade 12.9 studs, with stated F-250/F-350 and Excursion applications.
A 124.9mm hub bore paired with hub-centric construction is the defining feature of this YIZBAP two-piece set. Its 8x170mm pattern and 14×1.5 thread pitch establish the other core dimensions, while 12.9-grade studs are specified for buyers prioritizing the listed higher stud grade.
The 2-inch thickness sets the wheel’s outward position, and the 8x170mm vehicle and wheel patterns retain the same bolt layout across the spacer. YIZBAP lists a 124.9mm bore and 14×1.5 threads, with fitment for 2003–2015 F-250 and F-350 plus 2003–2005 Excursion; dual-rear-wheel vehicles are excluded. The listing states that its 12.9-grade studs have tensile strength up to 1000MPa. Two pieces are supplied, so the quantity suits a pair of positions.
- Hub-centric design with 124.9mm bore
- 2-inch thickness and 8x170mm pattern
- 14×1.5 thread pitch
- 12.9-grade studs with stated 1000MPa tensile strength
- Only two spacers are included, and dually vehicles are excluded.
Skip it if you need four spacers or have a dually; LUJIANI ZS-WS0034 offers four pieces but also excludes dual-rear-wheel models.
This pair fits buyers whose listed F-250, F-350, or Excursion application calls for hub-centric 8×170 spacers and 14×1.5 threads. Its two-piece quantity and explicit dually exclusion define its limits.

#3 · Four-Piece Set
3. LUJIANI Lug-Centric Spacers
- Weight: 29 lb
Best for: Four-piece non-dually F-250/F-350.
Why it ranks #3: Four spacers provide 2-inch thickness, 125mm bore, and M14x1.5 threads for listed Super Duty fitment; the listing clearly says lug-centric, not hub-centric.
A four-piece set with a 2-inch thickness equips all four wheel positions with matching LUJIANI spacers, an advantage for buyers planning a complete non-dually setup. The 8x170mm pattern, 125mm bore, and M14x1.5 pitch define its key interface dimensions for listed F-250 and F-350 Super Duty applications.
LUJIANI specifies 2005–2025 F-250 and F-350 Super Duty fitment, but explicitly excludes dual-rear-wheel models. The 8x170mm pattern and M14x1.5 studs identify the bolt interface, while the 125mm bore is the listed hub opening to compare with the vehicle. At 2 inches (50.8mm) thick, each spacer sets the outward offset. The product is lug-centric, not hub-centric, and gives a recommended torque range of 85–90 ft/lb for installation.
- Four spacers included
- 2-inch (50.8mm) thickness
- 8x170mm pattern with M14x1.5 studs
- 125mm bore and stated 85–90 ft/lb torque
- Not compatible with dual-rear-wheel models.
Skip it if you drive a dually; YIZBAP RY37105 also excludes dual-rear-wheel models, so choose a product whose listing supports your configuration.
For a non-dually F-250 or F-350 from the stated 2005–2025 range, this four-pack gives consistent 2-inch spacing at all positions. Its lug-centric design and dually exclusion are central fit considerations.

View on AmazonWhy it ranks #4: Four-piece 8×170 set lists a 125mm bore and M14x1.5 thread pitch, with fitment covering Excursion and F-250 Super Duty applications.
ECCPP states that its 2-inch spacers create clearance between the tire and hub assembly, directly addressing buyers seeking room for custom wheel fitment. The 8x170mm pattern, 125mm bore, and 14mmx1.5 thread pitch make the main interface specifications explicit for the listed Ford applications.
The listing describes a 2-inch outward shift that can produce a wider stance and additional clearance, tying the thickness to the intended wheel-position change. Its 8x170mm vehicle and wheel patterns, 125mm hub bore, and 14mmx1.5 pitch identify the relevant fitment dimensions. ECCPP names 2003–2005 Excursion and 2003–2015 F-250 Super Duty in its fitment details. It also states that the spacers meet OE specifications in form, fit, and function, without providing further construction details.
- 2-inch thickness for outward wheel placement
- 8x170mm vehicle and wheel patterns
- 125mm hub bore
- 14mmx1.5 stud/nut thread pitch
- The detailed fitment listing names 2003–2005 Excursion and 2003–2015 F-250, not a broader year range.
Skip it if you need a clearly stated later-model F-350 fitment; LUJIANI ZS-WS0034 lists F-350 Super Duty through 2025, excluding dually models.
ECCPP suits buyers seeking 2-inch spacing and added tire-to-hub clearance on the Ford applications named in its fitment details. Check the stated model range carefully, particularly if selecting for an F-350 or a later vehicle.

#5 · Broad Fitment Range
5. KAX Lug-Centric Spacers
- Weight: 29 lb
Best for: M14x2 lug-centric Ford fitment.
Why it ranks #5: Four-piece set lists a 125mm bore, M14x2 threads, and 90–100 ft/lb torque; its stated applications cover several Super Duty configurations.
M14x2 threaded studs and nuts distinguish this KAX 2-inch spacer set for buyers matching that thread pitch. Its 8x170mm pattern and 125mm center bore specify the other key dimensions, and the listing covers multiple Ford F-250 and F-350 applications alongside older Excursion models.
The listed 8x170mm vehicle and wheel patterns preserve the bolt layout, while the 125mm center bore identifies the opening for fitment checks. KAX specifies M14x2 studs and nuts, a 50mm thickness, and lug-centric construction with no lip. Its broad fitment text includes front and rear applications across several model years and configurations, so the vehicle-specific details matter. The maker recommends professional measurement tools such as PCD rulers or consulting the owner’s manual before selection.
- 8x170mm vehicle and wheel patterns
- M14x2 threaded studs and nuts
- 125mm center bore with no lip
- 50mm thickness and lug-centric construction
- Lug-centric design has no locating hub lip.
Skip it if you require hub-centric locating; YIZBAP RY37105 lists hub-centric construction with a 124.9mm bore, though its fitment range is narrower.
Choose this KAX option when the vehicle matches its extensive stated fitment and needs M14x2 threads with a 2-inch-class spacer. Its lug-centric, no-lip construction makes hub-interface requirements especially important.

View on AmazonWhy it ranks #6: Lists 2-inch thickness, 125mm bore, and M14x1.5 studs for F-250/F-350 fitment; the product explicitly is not hub-centric and quantity is two.
A 2-inch thickness paired with a 125mm bore and 8×170 pattern gives this KSP pair a defined fitment profile for listed F-250 and F-350 applications. Its lug-centric, explicitly non-hubcentric design helps buyers distinguish it from hub-centric options before choosing spacers for a wheel setup.
The 8x170mm bolt pattern and 14mmx1.5 studs specify the connection, while the 125mm bore identifies the hub opening to check against the vehicle. KSP describes the spacers as casting 6061-T6 aluminum billet, offering a lighter material with stated strength and durability. Heat-treated, hardened 10.9-grade Geomet bolts are cited as a vibration-reduction measure. The 2-inch thickness sets the amount the wheels move outward; the listed quantity is two pieces, not a four-piece set.
- 2-inch (50.8mm) thickness
- 8x170mm pattern and 125mm bore
- 14mmx1.5 studs with 10.9-grade Geomet bolts
- 6061-T6 aluminum billet construction
- Lug-centric rather than hub-centric, and supplied as a pair.
Skip it if you need hub-centric locating or four spacers in one set; the listing specifies a lug-centric pair.
For an F-250 or F-350 owner seeking a 2-inch outward wheel position, this pair offers specified 8×170 fitment and 14mmx1.5 studs. Its non-hubcentric design and two-piece quantity are important boundaries when planning the installation.

#7 · Limited Lifetime Warranty
7. Rough Country Spacers
- Weight: 11 lb
Best for: Wider-tire Super Duty clearance.
Why it ranks #7: Pair includes mounting hardware, M14x1.5 studs, and a stated limited lifetime warranty; its listed 4.8-inch center bore needs careful compatibility checking.
Rough Country states that these 2-inch spacers move the wheels outward to help make room for wider tires, directly serving Super Duty owners planning a broader tire setup. The 8×170 pattern and M14x1.5 studs define the bolt interface, while a 4.8-inch center bore supports specified wheel types.
The listed 8×170 bolt pattern and M14x1.5 studs identify the connection, while Rough Country says the 4.8-inch center bore supports both hub-centric OE wheels and lug-centric aftermarket wheels. That stated compatibility makes the spacer relevant to mixed wheel setups, although hub-centric availability is not universal across all models. The 2-inch thickness creates the outward offset intended to clear wider tires. The package contains a pair, so it does not provide four spacers for a full four-position setup.
- 2-inch thickness for outward wheel offset
- 8×170 bolt pattern with M14x1.5 studs
- 4.8-inch center bore
- Supports hub-centric OE and lug-centric aftermarket wheels
- Hub-centric compatibility is not available for all models.
Skip it if you need a four-piece set; LUJIANI ZS-WS0034 lists four 2-inch spacers for non-dually F-250 and F-350 applications.
A Super Duty owner seeking a pair of 2-inch spacers for wider-tire clearance can use this listing’s stated 8×170 fitment and wheel-type support. Verify the model-specific hub-centric availability and pair quantity.

View on AmazonWhy it ranks #8: Specifies 2-inch thickness and 12.9-grade studs, but uses M14x2 threads and lists older Excursion and F-250 model-year applications.
M14x2 studs distinguish this 2-inch YHTAUTO spacer from options specifying M14x1.5, making thread pitch the key selection detail for its listed older Ford applications. The 8x170mm pattern and 125mm bore provide the other fitment dimensions, with the product identified as lug-centric.
YHTAUTO lists compatibility with 2000–2002 Excursion and 1999–2002 F-250 Super Duty models, giving this spacer a narrower stated vehicle range than later-model listings. Its 8x170mm pattern, 125mm bore, and 2-inch thickness identify the wheel interface and outward spacing; the vehicle bore must be less than 125mm, according to the listing. M14x2 studs and 12.9-grade studs are specified, with a recommended torque of 85–90 ft/lb for installation planning.
- 2-inch thickness
- 8x170mm bolt pattern and 125mm bore
- M14x2 studs and lug nuts
- 12.9-grade studs; 85–90 ft/lb recommended torque
- Stated vehicle fitment is limited to older Excursion and F-250 models.
Skip it if you have a later-model Super Duty; KSP PERFORMANCE 6081KT lists F-250 and F-350 applications through 2024.
This is for buyers whose older Excursion or F-250 matches the stated range and requires M14x2 threads. Its lug-centric layout, 125mm bore condition, and model-year limits call for careful fitment selection.

View on AmazonWhy it ranks #9: Two-piece option lists 124.9mm hub dimensions and M14x2 threads for older Ford applications; its materials description conflicts between aluminum and steel.
This Wheel Accessories Parts listing is a two-piece, front-position set with hub-centric 124.9mm openings, making its placement and quantity unusually specific. The 8x170mm pattern and M14x2 threads identify the connection, while the stated early Excursion and Super Duty fitments guide its intended use.
The 2-inch thickness and matching 124.9mm vehicle-hub and wheel openings specify how the spacer interfaces at the hub and wheel. Wheel Accessories Parts lists an 8x170mm pattern and M14x2 threads, with fitment details focused on early Excursion, F-250, and F-350 Super Duty applications. The listing identifies this version as a front pair, so it is not a four-position set. Its additional material information describes forged high-tensile steel with electrodeposition painting for rust resistance.
- Hub-centric 124.9mm openings
- 2-inch thickness and 8x170mm pattern
- M14x2 thread studs
- Front-position pair with electrodeposition-painted steel
- Two spacers are supplied for front use, not all four positions.
Skip it if you need a four-position hub-centric kit; Wheel Accessories Parts 6061 Billet Aluminum lists four 2-inch spacers with M14x1.5 threads.
This front pair suits buyers with a matching early Ford application who specifically want hub-centric 124.9mm openings and M14x2 threads. Its front-only positioning, two-piece quantity, and stated model coverage set the fit boundary.

View on AmazonWhy it ranks #10: The 2-inch four-piece set matches 8×170 but lists a 130mm center bore and M14x2 threads, making careful hub and stud compatibility checks essential.
A 130mm center bore sets the Torchbeam spacer apart from listings specifying smaller bores, making bore measurement a first-order selection check. The four-piece set combines that dimension with a 2-inch thickness, 8x170mm pattern, and M14x2 studs for its stated Ford fitments.
Torchbeam specifies 8x170mm vehicle and wheel patterns, M14x2 studs and nuts, and a 130mm center bore with no lip. Those dimensions identify the bolt and hub interfaces, while the 2-inch thickness establishes the outward spacing. Four pieces are included for a full set. Listed applications include 2005–2010 F-350 Super Duty, 2010 F-250 Super Duty, and 2000–2002 Excursion, among others in the fitment text. The maker recommends professional measurement with a micrometer.
- Four spacers included
- 2-inch (50.8mm) thickness
- 8x170mm pattern with M14x2 threads
- 130mm center bore with no lip
- The 130mm no-lip bore may not suit vehicles requiring a smaller, locating hub interface.
Skip it if you need a 124.9mm hub-centric fit; Wheel Accessories Parts 8170-8170H-E142.2 lists that bore and M14x2 threads for specified early Ford models.
Torchbeam is for buyers whose listed Ford application matches its 130mm no-lip bore, M14x2 threads, and 8×170 pattern. Measure the hub interface carefully, since its bore differs from smaller-bore options.

View on AmazonAvoiding hub-bore and thread-pitch mismatches
A matching 8×170 bolt pattern does not by itself guarantee that a spacer fits your vehicle or wheel. These listings show why: several specify a 124.9mm or 125mm bore, while Torchbeam lists 130mm and Rough Country gives a 4.8-inch center bore. Thread pitch also differs: many list M14x1.5, while YHTAUTO, KAX, Wheel Accessories Parts’ two-piece option, and Torchbeam list M14x2.
A bore that does not locate correctly or studs and nuts with incompatible threads can prevent proper installation or secure clamping. Measure the vehicle hub and verify the wheel-side requirements rather than assuming nearby bore values are interchangeable.
Check the manufacturer’s fitment information for your exact year, trim, axle, and wheel setup. In particular, LUJIANI excludes dual-rear-wheel models, while YIZBAP also states that it does not fit dual rear wheels.
What changes with a two-inch spacer
A 2-inch spacer moves the wheel outward by the listed spacer thickness, so confirm clearance and hardware before choosing one. Product descriptions identify added tire clearance and a wider stance as intended uses, but they do not establish that a particular tire-and-wheel combination will clear your fender, suspension, or bodywork. Fit depends on the wheel offset, tire dimensions, vehicle configuration, and suspension setup—details not supplied consistently in these listings.
A further trade-off is design: hub-centric products advertise alignment to a specified hub bore, whereas several options explicitly identify themselves as lug-centric or not hub-centric. This roundup includes both, so do not treat the terms as interchangeable.
Verify the wheel’s center bore and the vehicle hub dimensions, then check the manufacturer’s installation guidance. If unsure, consult a qualified installer before driving; the product data alone cannot confirm safe clearance or handling for a custom setup.
How to Choose 8×170 Wheel Spacers
Hub bore and centering style
Look for a bore that matches your vehicle hub and verify whether the spacer is hub-centric or lug-centric. Wheel Accessories Parts’ four-piece set lists 124.9mm hub dimensions and calls itself hub-centric; YIZBAP also lists a 124.9mm hub bore. KSP and LUJIANI specify a 125mm bore but identify their spacers as not hub-centric or lug-centric.
Torchbeam lists a notably different 130mm center bore, and Rough Country lists a 4.8-inch center bore. Buyers who want a stated hub-centric design should prioritize options explicitly described that way; those considering lug-centric designs should verify fit and installation requirements with the vehicle and wheel details.
Stud thread pitch
Match the spacer studs and nuts to the thread pitch required by your vehicle and wheel; 8×170 does not specify thread pitch. M14x1.5 appears on the Wheel Accessories Parts four-piece, LUJIANI, ECCPP, YIZBAP, and KSP listings. M14x2 is listed by YHTAUTO, KAX, Torchbeam, and Wheel Accessories Parts’ two-piece option.
Rough Country lists M14x1.5 studs. Buyers whose vehicle uses M14x1.5 should focus on that group, while M14x2 users should compare the other options—but confirm the exact requirement before ordering.
Do not mix pitches or assume that a spacer advertised for the same bolt pattern has the correct threads.
Pack size and vehicle configuration
Choose a pair or four-piece package according to how many wheels you intend to space, then check the product’s vehicle exclusions. Wheel Accessories Parts, LUJIANI, ECCPP, KAX, and Torchbeam list four pieces; YIZBAP, KSP, Rough Country, and Wheel Accessories Parts’ two-piece option list pairs. A four-piece package suits buyers looking to fit all four corners, while a pair may suit a two-wheel application or a buyer who only needs two spacers.
Application limits still matter: LUJIANI excludes dual rear wheels, and YIZBAP says it does not fit dually configurations. Confirm year, axle, and single- versus dual-rear-wheel setup rather than choosing by pack size alone.
Which 8×170 spacers should I choose?
Choose Wheel Accessories Parts Hub-Centric if you want four spacers, a stated 124.9mm hub bore, and M14x1.5 threads for a listed Super Duty application. For a two-piece hub-centric option with grade 12.9 studs, consider YIZBAP Hub-Centric Spacers, while checking its stated model-year range and dually exclusion. Buyers who specifically need M14x1.5 and a lug-centric four-piece set can compare LUJIANI Lug-Centric Spacers and ECCPP 2-Inch Spacers.
If your vehicle requires M14x2, KAX Lug-Centric Spacers lists a four-piece set and 125mm bore; verify your exact fitment. Do not select solely by 8×170: confirm hub bore, thread pitch, vehicle year, and rear-wheel configuration before purchase.

Frequently Asked Questions
How can I confirm the hub bore and stud thread on my specific truck?
Check your vehicle’s owner documentation or manufacturer fitment information, then verify the hub bore and wheel-stud thread pitch on the truck. Compare those measurements with the spacer listing, along with vehicle year and rear-wheel configuration. If any measurement is uncertain, ask a qualified technician to confirm it before ordering.
Do wheel spacers affect wheel bearing wear or vehicle handling?
They can affect bearing loads and vehicle handling because they move the wheels outward. The effect depends on the vehicle, spacer fit, installation, and use, so it cannot be determined from the 8×170 pattern alone. Confirm compatibility with your vehicle manufacturer or a qualified technician, and stop driving if you notice unusual vibration or looseness.
What installation and re-torque steps should I follow after fitting spacers?
Follow the spacer and vehicle manufacturers’ installation instructions, including the specified torque values and re-torque interval; these vary by application. Ensure mating surfaces are clean and the spacer seats correctly before fitting the wheel. Recheck fasteners as directed, and have a qualified installer handle the work if you are unsure.
How do I choose between hub-centric and lug-centric spacers?
Match the spacer’s design to your vehicle’s hub and the listing’s fitment details. Hub-centric options specify a hub bore intended to align with the vehicle hub; lug-centric options rely on the lug interface. Confirm the bore, thread pitch, vehicle application, and installation requirements rather than choosing by bolt pattern alone.
What should I check for a truck with single or dual rear wheels?
Confirm whether the listing covers your rear-wheel configuration before buying. Some product titles specify single rear wheel, SRW/DRW, or a dually exclusion, while others do not clearly state configuration. Check the exact vehicle year and axle position with the seller or a qualified technician if the listing is unclear.
Final Words
For a listed Super Duty application needing a four-piece set, the Wheel Accessories Parts hub-centric option is the strongest all-around choice in this roundup, with its stated 124.9mm hub dimensions and M14x1.5 threads. Other options may suit different needs, including a two-piece hub-centric set or lug-centric designs. Before deciding, verify hub bore, thread pitch, vehicle year, and rear-wheel configuration; 8×170 alone does not confirm fit.
