1958–70 Impala Gold Zinc 8" Dual Power Brake Booster Kit | B-Body

8" Dual Diaphragm Zinc Power Brake Booster Kit: 1958–70 Chevy Impala & Full-Size B-Body

1958–70 Impala  Zinc 8" Dual Power Brake Booster Kit | B-Body

Give your full-size Chevy the stopping power it needs with a booster kit that looks like it came from the factory. This complete kit pairs the PB8531 8" dual diaphragm booster with matching gold zinc mounting brackets made for 1958–1970 Impala, Bel Air, Biscayne, Caprice, and other full-size Chevys. 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 engines, and aftermarket heads that often crowd a full-size booster. The dual diaphragm design delivers the strong assist a heavy full-size car needs for a firm, confident pedal. The slotted brackets let you fine-tune the booster’s position during installation, 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.
