Ford 73-84 F100, F150, Bronco Rear 13" Big Brake Kit

$2,115.00

1973-84 Ford F100, F150 and Bronco rear 13 in big brake kit with 4-piston calipers, drilled and slotted rotors and internal parking brake. Bolts to the factory axle.

  • Built around 17 inch wheels - the big brake answer for a truck that is not moving to 18s.
  • Bolt-on to the stock axle - radial and laser cut brackets locate on the factory flange with no modification.
  • Wilwood FNSL 4-piston - proportioned for the rear so the axle works without locking early.
  • Parking brake included - an internal drum style assembly rather than a lever that fades with the pads.
  • Drilled and slotted rotors - in the kit; not an option line at checkout.
  • A number you can measure - 2.36 inch flange offset tells you yes or no before you order.

A 13" kit utilizing 4-piston calipers, aluminum hats, machined 6061 AL radial brackets, and laser cut brackets to bolt up to the factory axle without modification. Designed fit 73-84 Ford F100, F150 trucks and Bronco with Big Ford Old Style axle flanges and a 2.36" offset. This kit is designed and machined in-house. Includes drilled/slotted rotors and internal drum style parking brake assembly.

*Wheel size requirement: Fits inside most 17" wheels.

NOTE: Fits bolt-in style sealed bearing axles, not tapered roller bearing (unless it has been converted to a sealed bearing).

This kit DOES NOT fit Ford 8.8 c-clip style axles. If you have an axle with that style in your 80-96 F150/Bronco, see our Ford 80-96 F100, F150, Bronco Rear 14" Big Brake Kit.

Please verify your flange dimensions with the image below. This can be done without removing anything simply by measuring the flange at the back side of the drum. Even if your model is listed below, if it does not have the correct flange measurements then the kit will not fit.
