7in Dual Power Booster 1-1/8 in Bore Master

The 7in Dual Power Booster 1-1/8 in Bore Master is a professional-grade hydraulic brake system component designed for vehicles that require robust stopping power and reliable pedal feel. This dual power booster is ideal for enthusiasts building high-performance street machines, restoring classic muscle cars, or upgrading heavy-duty trucks.

Featuring a 7-inch diameter and a 1-1/8 inch bore master cylinder, this booster amplifies hydraulic pressure through dual-stage vacuum assistance, allowing lighter pedal pressure to generate full braking force across all four wheels. The dual-chamber design ensures redundancy, meaning if one power section fails, the other continues to operate, enhancing safety and reliability in demanding driving conditions.

Installers and brake system builders recognize the 7in Dual Power Booster as the ideal solution for resto-mod projects, custom hot rods, and vehicles where original power brake systems may be undersized. Its compact dimensions of 11 x 11 x 18 inches allow for integration into tight engine bays while providing the mechanical advantage necessary for responsive street performance.
