Fitment & Compatibility

This AERO6/SRP front hub conversion uses the spindle applications detailed in the table below. Listed 1968 Bel Air, Biscayne, Caprice and Impala entries exclude the single-piston power-disc setup. During 1969–1970, the full-size Chevrolet rows distinguish disc and drum spindles, with Brookwood, Kingswood, Townsman and Estate coverage dependent on the particular year. The Corvette application is the 1969–1982 C3 spindle. Match that hardware before selecting the supplied 5 × 4.50/4.75-inch hubs and 1/2-20 studs. DS-1589 supplies the 14-inch brake envelope; hydraulic hoses are separate.
