1968-76 Corvette Power Brake Booster, Brand New Black 9" Dual Diaphragm

1968–1976 Corvette 9" Dual Diaphragm Power Brake Booster, Black, Direct OEM Replacement

Bring back the firm, confident pedal feel your C3 Corvette had when it left St. Louis. This 9-inch dual diaphragm power brake booster is a direct OEM-style replacement built for 1968–1976 Corvettes. It bolts straight into place with no modifications, no guesswork, and a guaranteed fit.

Whether you’re doing a full frame-off restoration or replacing a tired, leaking booster on your weekend cruiser, this unit restores the braking power and pedal response a classic ‘Vette deserves. It’s built in the Delco style with the correct YZ pushrod and replaces the Bendix-style booster, so it fits right where the original did. The factory-correct black finish looks at home under the hood, whether you’re heading to a show or out on the open road.

Why Upgrade?

A worn booster can leave you with a hard pedal, longer stopping distances, and vacuum leaks that hurt engine performance. A new dual diaphragm booster gives you consistent power assist and smooth, predictable stops, along with peace of mind every time you hit the brakes.

Stop like you mean it. Restore your C3 the right way.
