Mastodon 7" Vacuum Dual Diaphragm Power Brake Booster – Chrome

Compact 7" dual-diaphragm chrome brake booster — the workhorse booster for street rods and small-to-mid-size muscle car builds. The dual-diaphragm design delivers approximately 20–27% more stopping power than a single-diaphragm unit while keeping the smaller package size that fits tight engine bays.

Polished and chrome-plated finish for a clean show-quality look. Universal fit works across most GM, Ford, truck, and passenger applications.

• Master cylinder studs: 3.375" centre-to-centre
