1955–57 Chevy Gold Zinc 8" Dual Power Brake Booster Kit | Tri-Five

8" Dual Diaphragm Gold Zinc Power Brake Booster Kit: 1955–1957 Chevy Tri-Five

1955–57 Chevy Gold Zinc 8" Dual Power Brake Booster Kit | Tri-Five

Give your Tri-Five Chevy modern stopping power with a booster kit that looks like it belongs under the hood. This complete kit pairs the PB8531 8" dual diaphragm booster with matching gold zinc straight brackets made for 1955, 1956, and 1957 Chevy cars. The gold zinc finish has the look of original-equipment boosters, so it suits restorations and resto-mods. The zinc plating also protects against rust and corrosion.

The compact 8" size leaves room for tall valve covers, big-block swaps, and aftermarket heads that often crowd a full-size booster. The straight brackets mount the booster in line with the pedal for a clean installation on the Tri-Five firewall, and the included rod extension and clevis connect it to your brake pedal. It uses standard GM bolt patterns, including the 3-3/8" square pattern, so it works with common GM master cylinders. Every booster is vacuum tested and passes a quality inspection before it ships.
