Recommendations for 5 lug C10 Fitment: The 5.25" backspacing front wheels fit trucks with the factory-track width front suspension The 4.5" and 4.75" backspacing front wheels are optimized for narrowed front spindles (common on lowered applications such as CPP spindles - this also gives the wheel a deeper dish). The 5.5" backspacing fit rear wheels with factory-length axles. The 4.0" backspacing fit rear wheels on rear axles that have been narrowed 1.5" per side (3" total). These wheels feature a nostalgic deep-dish style that works best with factory-style brakes. Trucks with big-brake kits require a wheel with more positive offset, but this eliminates the classic deep-dish design & style (since the center of the wheel is moved out flush with the outer edge of the wheel). Customers with big-brake kits should consider using wheels designed for that application (i.e., Rocket Racing "Attack" wheels). The vehicle application data for this wheel is a general guideline only. Check bolt pattern, width, back-space (or offset), center bore, and brake caliper clearance to confirm that the desired wheel will fit your vehicle. Many vehicles have been modified & these changes may cause wheel fitment issues (i.e., axle swaps, disc brake / big-brake conversions, suspension changes, and other modifications). ALWAYS verify the wheel actually fits on your vehicle BEFORE mounting tires. Wheels are non-returnable after tires have been mounted.
