Description
Aeroflow GM 7″ Dual Diaphragm Vacuum Brake Booster (Chrome Finish)
Dramatically improve your braking performance and pedal effort while freeing up critical engine bay clearance in custom GM and V8 applications.
Engineered for Superior Braking & Engine Bay Clearance
The Aeroflow Performance AF300-105C GM 7″ Dual Diaphragm Brake Booster is the ultimate solution for drivers seeking effortless pedal feel and enhanced stopping power without sacrificing valuable under-bonnet space. Standard 11-inch factory boosters often clash with tall rocker covers or performance V8 engine swaps. Aeroflow solves this by stacking two smaller diaphragms inside a compact 7-inch housing, delivering equivalent or greater vacuum assist in a significantly reduced footprint.
Finished in mirror-polished chrome, this high-performance booster provides an unbeatable show-car aesthetic alongside reliable street and circuit performance. Ideal for restoring lost pedal assist or upgrading from manual brakes.

- ☑ Dual diaphragm design for maximum vacuum assist in a compact 7″ diameter
- ☑ GM-specific bolt pattern for direct custom and street rod retrofits
- ☑ Show-quality polished chrome outer finish
- ☑ Dramatically reduces brake pedal force needed for effective stopping
- ☑ Solves engine clearance issues with tall V8 valve covers
