Fitment & Compatibility

C5/C6 Corvette and Cadillac XLR entries require the listed hub and brake configuration. The many classic GM applications require a Ridetech hub spindle, so an original-spindle car is not covered by its model/year alone. Hoses are separate: DS-1079 identifies 220-8176 for C5 and 220-9100 for C6, with other converted installations checked individually. Match the wheel template and correct hub registration.

Listed models: Chevy II; Corvette; Skylark; Special; Sportwagon; Chevelle; El Camino; 442; Cutlass; F85; Vista Cruiser; Beaumont; GTO; LeMans; Tempest; Gran Sport; Camaro; Cutlass Supreme; Firebird; GS 350; GS 400; Nova; GS; GS 455; Sprint; Ventura; Apollo; Omega; XLR. Use the fitment table below for the individual years, submodels and equipment conditions.
