8" Dual Diaphragm Gold Zinc Power Brake Booster Kit: 1964–1972 GM A, F, and X Body

8" Dual Gold Zinc Power Brake Booster Kit | 1964–72 GM A F X Body

Bring strong stopping power to your classic GM 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 and all the pedal hardware you need. 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 clears tall valve covers, big-block engines, and aftermarket heads that often get in the way of a full-size booster. The dual diaphragm design delivers a firm, confident pedal, and the included rod extension, clevis, and pin connect the booster to your brake pedal. It uses standard GM bolt patterns, including the 3-3/8" square firewall pattern, so it works with common GM master cylinders. Every booster is vacuum tested and passes a quality inspection before it ships.
