YIZBAP Wheel Adapters 8x6.5→8x170 for Silverado/Sierra — 1.5in 6061‑T6 with 12.9‑Grade Studs

These YIZBAP wheel adapters convert an 8x6.5 (8x165.1mm) vehicle bolt pattern to accept 8x170mm wheels so you can mount F250/F350 wheels on compatible Silverados and similar trucks.

If you want the look, offset, or wheel options available for Ford F-series 8x170mm wheels on a vehicle with the 8x6.5 (8x165.1mm) bolt pattern, these YIZBAP adapters provide a bolt-through solution that preserves hub centering and increases stud strength. Machined from 6061-T6 aluminum and fitted with high-strength 12.9-grade studs, this adapter set is engineered for a precise fit and long-term durability when used on the correct vehicle and wheel combinations.

Which vehicles and wheels are compatible with these adapters?

These adapters are designed specifically to allow 8x170mm wheels (commonly used on 2003–2024 Ford F250/F350) to be mounted on vehicles with an 8x6.5 (8x165.1mm) bolt circle. They do not convert the other way—an 8x6.5 wheel will not fit onto the adapter.

• Vehicle PCD (vehicle side): 8x6.5 (8x165.1mm).
• Wheel PCD (wheel side): 8x170mm — typical F250/F350 wheels.
• Confirm hub bore: 126.15mm for correct centering and fitment.
• Check listed compatible models (Ram, Silverado, Sierra, Yukon, Suburban, Savana, Express) before purchase.

How strong and reliable are the studs and adapter construction?

YIZBAP uses hardened 12.9-grade threaded studs and CNC-machined 6061-T6 aluminum bodies with an anodized finish. The studs have a tensile strength up to 1000 MPa, offering higher mechanical strength than common 10.9-grade alternatives.

• Stud material/grade: 12.9 — high tensile strength for load handling.
• Adapter material: 6061-T6 aluminum with anodized surface for corrosion resistance.
• Manufacturing: CNC precision machining for accurate bolt pattern and hub bore.
• Thickness: 1.5 inches (38.1 mm) of spacer depth; thread pitch 14x1.5.

What installation details and precautions should I know?

Installation requires correct torque, hub-centered seating, and verification of wheel backspacing and brake clearance. Use factory torque specs for wheel nuts, verify stud engagement, and re-check torque after initial road use.

• Only fits when wheels are 8x170mm; not compatible with 8x6.5 wheels mounted to the adapter.
• Ensure hub bore 126.15mm matches wheel center or use hub-centric rings if necessary.
• Confirm no interference with brake components, fenders, or suspension parts before driving.
• Follow torque sequence and re-torque after 50–100 miles for safe operation.

Who is this for: The YIZBAP 8x6.5-to-8x170 adapters are for truck owners who want to fit Ford F250/F350 8x170mm wheels on compatible GM and other 8x6.5 vehicles — commonly enthusiasts swapping wheel styles between brands, fleets replacing wheels, or anyone needing wider wheel options. They suit drivers who verify fitment, follow installation best practices, and prioritize durable, precisely machined components rather than using temporary or improvised solutions.
