Universal 9" Delco-Style Power Brake Booster | GM 1955–1975

Restore factory-style power brakes on your classic GM with a brand-new 9" Delco-style booster. Its larger 9" diaphragm delivers strong, consistent assist with the factory look and feel, making it a natural choice for restorations, resto-mods, and power brake conversions. The standard GM 3-3/8" square stud pattern on the back bolts up to a wide range of GM cars from 1955 to 1975, and the long threaded pushrod lets you set the pedal rod length to suit your setup.

Every booster is brand new, never rebuilt. Each one is quality control tested and approved before it ships and is backed by a limited lifetime manufacturer’s warranty.

Booster only. Mounting brackets, rod extension, clevis, and master cylinder are not included. Reuse your existing brackets if they match the 3-3/8" square pattern, or choose the brackets that fit your vehicle.
