Fitment & Compatibility

Match the spindle journals and bracket points to the actual Chevrolet disc/drum application in DS833. The passenger-car and Corvette entries cover different configurations, even where their calendar years overlap. Inspect the retained spindle before building the new hub and rotor assembly. Wheel mounting requires full contact support: purchase the specified spacer when the contact surface overhangs the hub, or use the specified shield with a non-overhanging stamped steel wheel. Recheck tire/fender clearance for the outward wheel-position change and verify the five-lug pattern. Flexible hoses are chosen separately, with the route checked at steering lock. Measure the complete conditional 15-inch wheel profile and adjust bearings and caliper alignment before the brake test.

Check the individual year, model, submodel and equipment conditions in the fitment table below before ordering.
