The 7" Dual Diaphragm power brake booster is zinc plated and part of the Compact-10 Series.
Before a zinc finish is applied, this GM truck brake booster is hand polished for a top quality finish.
Ideal for most disc/drum brake applications, the 1-1/8in Bore master cylinder and proportioning valve are included.
A direct fit to your factory firewall is provided by the Compact-10 mounting bracket and push rod assembly.
Designed to mount closer to the firewall at a more natural angle than a factory style booster, the Compact-10 series boosters give you the look and brake performance you want out of your truck.
