Fitment & Compatibility

Use the individual year, model and wheel-configuration entries below: the 2500 HD, 3500 HD and Suburban 3500 HD listings do not all share the same production range. Wilwood permits the specified iron/steel or aluminum spindle, but hub pilot, eight-lug pattern and wheel clearance still need checking. DS-1085 identifies front flexline kit 220-10979 as included; confirm its length, fittings and routing on the actual vehicle.

Listed models: Silverado 2500 HD; Silverado 3500 HD Pickup; Sierra 2500 HD; Sierra 3500 HD Pickup; Silverado 3500 HD; Sierra 3500 HD; Suburban 3500 HD. Use the fitment table below for the individual years, submodels and equipment conditions.
