7/8 Bore Aluminum Master Cylinder Kit, 70-74 E-body and 62-72 B-body

This kit includes Wilwood's premium all-aluminum tandem master cylinder with a 7/8" bore, pushrod, aluminum 2-4 bolt firewall adapter plate, and a custom-machined adjustable pushrod end to bolt directly to your factory pedal. 7/8 bore master provides positive, but comfortable pedal feel and increases clamping force at the caliper compared to larger bore master cylinders. Available in bright plated or black.
