Our firewall mount power brake booster kits are made to be compact and allow for clearance of any valve cover combination. Once installed the firewall, dash and steering column become triangulated making the entire assembly extremely rigid. The factory firewall to dash support must be removed. (Except on 1948-52 Ford & 1954-55 Chevy models). Kit includes firewall mount bracket with pedal assembly, power brake booster, master cylinder, proportioning valve, and all mounting hardware. Bracket also available separately. Please specify drum/drum, disc/drum or disc/disc. Booster available in 7”, 8” and 9” diameters. Please specify size when ordering.
