Ridetech 2.5" drop spindles for 1963–1970 C10 are supplied as a pair with caliper brackets and are intended for use with stock HD brakes (1 1/4" thick rotors) and some aftermarket systems. They deliver a sizeable lowered stance while keeping brake clearance and basic compatibility with common braking setups on vintage C10 trucks.
