YIZBAP Wheel Adapters 6x135→6x5.5 for F-150 — 1.5 in CNC 6061-T6 Hub-Centric

These YIZBAP 6x135 → 6x5.5 wheel adapters let you mount Silverado 1500 (6x139.7mm) wheels onto F-150 trucks with a 6x135mm bolt pattern, converting the wheel bolt pattern while maintaining hub-centric alignment.

If your F-150 has a 6x135mm bolt pattern but you want to use wheels designed for GM trucks (6x5.5 / 6x139.7mm), these adapters provide a precise, durable solution. Machined from 6061-T6 aluminum with anodized finish and fitted with high-strength Grade 12.9 studs, they convert the wheel bolt pattern and center the wheel on the vehicle hub. The adapters are 1.5 inches (38.1mm) thick, include an 87.1mm wheel bore and a 78.1mm vehicle hub centric bore, and are built to strict tolerances for fit and stability.

How do these adapters change wheel compatibility?

They act as an interface between the truck hub and the wheel, taking the vehicle’s 6x135 bolt layout and providing a 6x5.5 bolt pattern so Silverado/GMC wheels can be bolted on. These are hub-centric, which helps keep the wheel aligned to the hub and reduces vibration risk.

• Converts vehicle bolt pattern from 6x135mm to wheel bolt pattern 6x139.7mm (6x5.5).
• Hub bore: 87.1mm; vehicle centric bore: 78.1mm for accurate centering.
• Thickness: 1.5 inches (38.1mm) to provide clearance and correct offset.

Will these fit my truck and my wheels?

They work only on vehicles with a 6x135mm bolt circle and are intended for wheels with a 6x139.7mm bolt circle (commonly written as 6x5.5). Do not use these to fit 6x135mm wheels; they are specifically for running GM 6x5.5 wheels on compatible Ford hubs.

• Vehicle compatible examples: 2015–2025 F-150 (most trims except Raptor), 2015–2024 Expedition, 2015–2025 Navigator.
• Wheel compatible examples: Silverado 1500, Sierra 1500, Tahoe 4WD, Yukon, Escalade, Suburban, and other 6x139.7mm GM wheels.
• Confirm your hub bolt pattern and wheel PCD before purchasing to ensure proper fitment.

What materials and hardware ensure safety and longevity?

YIZBAP manufactures the spacers from aircraft-grade 6061-T6 aluminum and uses CNC machining for consistent tolerances. The studs are Grade 12.9 high-tensile bolts, offering greater strength than 10.9-grade studs for improved structural reliability under load.

• 6061-T6 aluminum body with anodized surface for corrosion resistance.
• Grade 12.9 threaded studs with tensile strength around 1000 MPa for robust clamping.
• Precision CNC machining for true bolt-hole alignment and hub-centric fit.

How do I install and what should I check after installation?

Installation requires removing the factory wheel, bolting the adapter to the vehicle hub using the stock lug nuts or supplied hardware, then mounting the wheel to the adapter studs. Torque to manufacturer specifications and recheck torque after the first 50–100 miles for safety.

• Hand-thread studs then torque in a star pattern to specified values.
• Verify wheel clearance for brakes, calipers, and suspension components with the added 1.5" spacer thickness.
• Inspect studs and adapter bores periodically and re-torque as needed.

Who is this for: These adapters are aimed at truck owners who want to use GM-style 6x5.5 (6x139.7mm) wheels on F-150 or other vehicles with a 6x135mm hub pattern — ideal for swapping factory Ford wheels for Silverado/Sierra wheels, running aftermarket wheels with a GM bolt pattern, or achieving a specific stance or fitment without changing hubs. They suit DIY installers and professional shops that prioritize precision machining, high-strength hardware, and hub-centric accuracy. Always verify exact vehicle and wheel PCD and follow safe installation and maintenance practices.
