Premium Universal 7 Inch Dual Diaphragm Power Brake Booster Chrome Steel Finish With Sick Stopping Power And Heavy Four Bolt Mount For Street Rods And Custom Builds

Single 7 inch dual brake booster for custom builds
✔️ 4 bolt mount, 3 3/8 inch spacing, chrome plated steel body

Each order ships as a single unit designed to deliver solid stopping force without eating up dashboard space. It fits perfectly on small to mid size street rods, hot rods, and custom restorations that need reliable pedal assist. Garage builders will find this a handy swap when upgrading older master cylinder setups for safer highway cruising. ✅ Dual vacuum chamber design cuts pedal travel in half
✅ Seven inch round housing slides into tight motor compartments
✅ Heavy duty four bolt flange bolts straight to the firewall
✅ Three point eight seven five inch center bore handles any standard shaft

💡 Why pick a dual chamber brake booster over traditional single diaphragm units?
A twin setup splits suction load across two chambers, giving you harder bite and less foot pressure during sudden stops. Keep this handy gear guide in mind before your next install.
- Match the output shaft length to your current master cylinder depth
- Seal all vacuum connections with proper rubber tubing to prevent leaks
- Torque the mounting nuts evenly to avoid firewall flex while braking
