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

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

Add show-quality looks and strong stopping power to your classic GM in one bolt-on kit. This complete kit pairs the PB8531C chrome 8" dual diaphragm booster with plated mounting brackets and all the pedal hardware you need. The bright chrome finish turns the booster into an engine bay centerpiece, and the dual diaphragm design delivers a firm, confident pedal from a compact package.

The 8" size clears tall valve covers, big-block engines, and aftermarket heads that often get in the way of a full-size booster. 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.
