Fitment Notes

The Chevrolet K10 uses a 6-139.7mm (6x5.5) bolt pattern. This is also known as the PCD (Pitch Circle Diameter). When shopping for aftermarket wheels, ensure the center bore matches or is larger than the vehicle's hub. If the wheel bore is larger, hub centric rings are recommended to prevent vibration.

Lug Hardware: Always use the correct lug nuts or lug bolts for your specific vehicle year. Torque them to the manufacturer's specified setting.
