The Speedmaster PCE165.1004.01 is an 8-inch universal dual diaphragm brake booster finished in zinc for corrosion resistance. The dual diaphragm design delivers increased vacuum assist over single diaphragm units, helping provide firmer, more confident braking with less pedal effort.
Designed as a universal-fit unit, this booster is well-suited for custom builds, restorations, and performance street applications where a reliable, compact 8-inch booster is required. Always verify mounting dimensions and port specifications against your specific vehicle or application before installation.
