8 Lug Same Pattern Wheel Adapters

8x6.5" (8x165.1) same pattern adapters: Silverado 2500, Sierra 2500HD, Suburban 2500, Express 3500 and Ram 2500

• 14x1.5 thread, 116.6mm to 117mm hub: the 8x6.5" pair with 14x1.5 studs (125.6mm center bore, 1" to 3"), which clears these hubs and centers on the studs, fits the Silverado 2500 1999–2010, single-rear-wheel Silverado 3500 2001–2010, Silverado 1500HD 2001–2006, Suburban 2500 1992–2013, Avalanche 2500 2002–2006, C/K 2500 HD and single-rear-wheel C/K 3500 1988–2000, the GMC Sierra 2500HD 1999–2010, single-rear-wheel Sierra 3500HD 2001–2010 and K2500 (4WD) 1988–2000, and the GMC Yukon XL 2500 2000–2013. On the single-rear-wheel Express 3500 1996–2023 the front hub is 116.7mm; one source lists a larger rear hub pilot on these vans, so measure the rear hub before ordering a rear pair.
• 14x1.5 thread, 121.3mm hub: the Ram 2500 2012–2026 and single-rear-wheel Ram 3500 2012–2026 take the same 8x6.5" pair with 14x1.5 studs.
• 9/16"-18 thread, 121.3mm hub: the Ram 2500 1994–2011 and single-rear-wheel Ram 3500 1994–2011 take the 8x6.5" pair with 9/16" studs (125.6mm center bore, 1" to 3") or the 8x6.5" hub centric pair with 9/16" studs (121.2mm bore, 2", for factory wheels with a nominal 121.3mm center bore; measure the hub and wheel center bore before ordering; confirm that the wheel bore clears the wheel-side pilot and both mounting faces seat flush), whose listing excludes the rear axle of 4WD trucks and any locking hub.

The NV1500, NV2500 and NV3500 2012–2021 are 8x165.1 with a 14x1.5 thread and take the 8x6.5" pair with 14x1.5 studs; their hub diameter is not confirmed (outside sources give 117mm or 121mm), so measure it first. The 8x6.5" pair with 1/2" studs (125.6mm center bore, 1.5" or 2") is also offered for trucks whose studs carry that thread.

8x180 same pattern adapters: Silverado 2500HD and single-rear-wheel Silverado 3500HD 2011–2022; Sierra 2500HD in 2011, 2016 and 2022

8x180 with a 14x1.5 thread and a 124.1mm hub: the Silverado 2500HD and single-rear-wheel Silverado 3500HD 2011–2022 and the GMC Sierra 2500HD in 2011, 2016 and 2022 take the 8x180 pair (125.6mm center bore, 14x1.5 studs, 1.5" or 2"), which clears the hub and centers on the studs. Model years 2023–2026 are not yet confirmed by an outside source for all of these trucks.

8x170 same pattern adapters: F-250 Super Duty, single-rear-wheel F-350 Super Duty and Excursion

The F-250 Super Duty and single-rear-wheel F-350 Super Duty 1999–2002 and Excursion 2000–2002 use 8x170 with a 14x2.0 thread and a 124.9mm hub. The F-250 Super Duty and single-rear-wheel F-350 Super Duty 2003–2025 use 8x170 with a 14x1.5 thread on the same hub (2026 is not yet confirmed by an outside source). Sources disagree on the exact thread changeover, so on a 2002, 2003 or 2004 Super Duty check the stud thread (14x2.0 or 14x1.5) before ordering.

• Hub centric, one pair per axle, 2": these pairs are for factory wheels with a nominal 124.9mm center bore (125.0mm on the Excursion); measure the hub and wheel center bore before ordering; confirm that the wheel bore clears the wheel-side pilot and both mounting faces seat flush. For 1999–2002, the 8x170 hub centric front pair with 14x2.0 studs (125.1mm bore) goes on the front axle and the 8x170 hub centric rear pair with 14x2.0 studs (125.3mm bore) on the rear axle; the 1999–2002 front pair may not fit the rear axle without machining, so order the pair for each axle. For the F-250 Super Duty and single-rear-wheel F-350 Super Duty 2003–2025, the 8x170 hub centric front pair (125.1mm bore) goes on the front axle and the 8x170 hub centric rear pair (125.3mm bore) on the rear axle, both with 14x1.5 studs.
• Bolt-on, 1.5" to 3": the 8x170 pair with 14x2.0 studs and the 8x170 pair with 14x1.5 studs (125.6mm center bore) for the same trucks by thread.

How to choose an 8 lug same pattern adapter

Bolt-on spacers bolt directly to factory studs using separate hardware and feature their own integrated studs to mount the wheel, ideal for wider setups. A same pattern adapter is built that way, with the same 8 lug pattern on both faces; the 8x170 axle pairs and the 121.2mm 8x6.5" pair are also bored to the hub, so the hub, not the studs, centers them.

• Thread: the pair's studs must carry your truck's thread: 14x1.5, 14x2.0, 9/16"-18 or 1/2"-20 on the 8 lug pairs here. On a hub with wheel studs, lug nuts in your truck's stud thread and the pair's required seat clamp the pair to the hub (your own nuts only if they meet both). The wheel then mounts on the pair's studs with lug nuts that match both the pair's stud thread and your wheels' seat (check whether the listing includes nuts).
• Hub bore: a hub centric pair's bore matches the hub; a lug centric pair's 125.6mm center bore only has to clear it. If your truck is not named above, measure the hub, or measure your bolt pattern if you are unsure of it.
• Axle: the 8x170 hub centric pairs are sold per axle: the front hub centric pair goes on the front axle and the rear hub centric pair on the rear axle, and the 1999–2002 front pair can need machining to fit a rear axle. The 121.2mm 8x6.5" hub centric pair is not for the rear axle of 4WD trucks or any locking hub.
• Thickness: 1" to 3" depending on the pair. Start with the thinnest that clears; on a thin pair whose listing says so, factory studs that stand proud of its face and stop the wheel seating flush need shortening.
• Torque: torque to your truck maker's specification and check the nuts again after the first 50 to 100 miles.

Common questions

Is a same pattern wheel adapter the same as a wheel spacer? Yes. These bolt-on wheel spacers keep the same bolt pattern on both faces and move each wheel outward by the adapter's thickness. They do not convert the pattern. To run wheels with a different bolt pattern, see wheel adapters.

Which 8 lug adapters fit a Silverado 2500? Silverado 2500 1999–2010: the 8x6.5" pair with 14x1.5 studs. Silverado 2500HD 2011–2022: the 8x180 pair.

Which adapters fit a Ram 2500 or single-rear-wheel 3500? Ram 2500 1994–2011 and single-rear-wheel Ram 3500 1994–2011: the 8x6.5" pair with 9/16" studs, or the 121.2mm hub centric 9/16" pair (for factory wheels with a nominal 121.3mm center bore; measure the hub and wheel center bore before ordering; confirm that the wheel bore clears the wheel-side pilot and both mounting faces seat flush; not on the rear of a 4WD or on locking hubs). 2012–2026 single rear wheel: the 8x6.5" pair with 14x1.5 studs.

Which adapters fit an F-250 Super Duty or single-rear-wheel F-350 Super Duty? 1999–2002: the 8x170 hub centric rear pair and front pair with 14x2.0 studs (for factory wheels with a nominal 124.9mm center bore; measure the hub and wheel center bore before ordering; confirm that the wheel bore clears the wheel-side pilot and both mounting faces seat flush; one per axle; the front pair may need machining to fit the rear), or the 8x170 pair with 14x2.0 studs. F-250 Super Duty 2003–2025 and single-rear-wheel F-350 Super Duty 2003–2025: the same pairs with 14x1.5 studs (the hub centric pairs are for factory wheels with a nominal 124.9mm center bore; measure the hub and wheel center bore before ordering; confirm that the wheel bore clears the wheel-side pilot and both mounting faces seat flush). On a 2002, 2003 or 2004 truck, check the stud thread first: sources disagree on the changeover.
