The Detroit Speed Inc. Hub Adapter Kit uses heat treated alloy steel adapters to allow the use of SKF Racing X-Tracker hubs on the factory 1991-96 Corvette spindle. The use of high performance hubs results in improved hub stiffness and performance, reduced brake caliper piston knock-back as well as improved hub durability. The kit is 100% bolt-on system that includes all required mounting hardware and electrical connectors. The wheel hub remains in the factory location and does not affect wheel offset or brake system compatibility as well as retains full functionality of the ABS system. Our hub adapters also feature a corrosion resistant black coating to ensure durability and longevity.
