FFG 1967-79 F100 Wilwood Master Cylinder Kit
Wilwood Master Cylinder Kit – 1967–1979 Ford F-Series & 1978–79 Bronco
Fat Fender Garage is proud to offer our Wilwood Master Cylinder Kit for 1967–79 Ford ½-ton & ¾-ton trucks and 1978–79 Broncos. We run this exact setup on our shop builds—and now it’s available to the DIY crowd.
Upgraded to disc brakes? Running bigger wheels or more power? This kit gives you the stopping performance you need in a clean, bolt-in package.
Lowered Truck Friendly:
If your truck is lowered more than 4", select the Lowered Option. This includes a shorter pushrod and a compact 7" booster to clear tight engine bays and avoid interference with valve covers and other components.
Booster Selection Guide:
- 8" Booster – Ideal for most stock or mildly lowered setups
- 7" Booster – Recommended for trucks lowered more than 4" (especially Level 2 drops or air ride)
Kit Includes:
- Wilwood Tandem Master Cylinder – 1" bore, lightweight die-cast construction
- Tuff Stuff Dual Diaphragm Booster – Choose 7" or 8" depending on your build
- Fat Fender Garage Custom Pushrod – Standard or shortened
- Firewall Plate & Grommet – Clean, sealed finish
- Mounting Brackets – Because no one kept those from the '70s
- Optional: Wilwood Adjustable Proportioning Valve Kit – Strongly recommended for disc/disc or mixed setups
Note: The 8" booster works great for most trucks. But if you're dropping the ride more than 4", go with the 7" booster to keep things from clashing under the hood.
