Fitment & Compatibility
Use this front hat with the specified C10 ProSpindle brake conversion. Its 1.380-inch offset and 3.06-inch center locate the ring on the matching hub; the flange offers 5 x 4.75 and 5 x 5.00-inch clearance patterns. The rotor fastens separately on a twelve-hole 8.75-inch circle. Confirm the actual ProSpindle kit and required rotor bolts rather than selecting from a truck model alone.
