Ford 76-79 F100, F150, Bronco 13" FRONT Big Brake Kit (4WD)

$2,315.00

Wilwood 13-inch front big brake kit for 1976–79 Ford F100, F150 and Bronco 4WD, with 6-piston calipers and drilled and slotted rotors. Fits inside most 17-inch wheels.

  • Bolts to the knuckle you have - radial 6061 brackets mount directly to the factory 5-bolt Dana 44.
  • Wilwood 6-piston FNSL - clamping force spread across six pistons instead of one sliding caliper.
  • Drilled and slotted rotors at no charge - LSMFG rotors are included in the kit.
  • 17 inch wheels still fit - 13 inch rotors sized to live behind most 17s.
  • Hoses your way - braided stainless in the kit; or leave them out if yours are being made.
  • Machined aluminum hats - the interface that keeps the rotor true and the weight down.

Install Level: Advanced

Requires the factory disc brake Dana 44 5-bolt knuckle and spindle.
Wilwood Black and Wilwood Red calipers add a 2–4 week lead time.
Choose braided stainless hoses or none at checkout.
