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

8" Dual Diaphragm Chrome Power Brake Booster Kit: 1958–1970 Chevy Impala and Full-Size 

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

Give your full-size Chevy the stopping power it needs and an engine bay that turns heads. This complete kit pairs the PB8531C chrome 8" dual diaphragm booster with polished mounting brackets made for 1958–1970 Impala, Bel Air, Biscayne, Caprice, and other full-size Chevys. The bright chrome finish makes the booster an engine bay centerpiece. The dual diaphragm design delivers the strong assist a heavy full-size car needs for a firm, confident pedal.

The compact 8" size leaves room for tall valve covers, big-block engines, and aftermarket heads that often crowd a full-size booster. 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.
