A 14" disc brake upgrade with 6-piston FNSL calipers designed for 63-87 GM 5-lug trucks using Wilwood Iron ProSpindles. Complimentary to our 14" rear kit HERE which uses matching caliper bodies but with the appropriate internal bore sizes to keep the front/rear bias proportional.
Utilizes machined billet LSMFG hubs, hats, and radial brackets, equivalent to Wilwood part numbers 140-15942, 140-15942-D, 140-15942-R, 140-15942-DR
Note: Requires Wilwood Iron ProSpindles such as 831-15931, 831-15932
Wheel size requirement: Fits inside most 18" wheels
NOTE: Model years 1963-72 will require updating to 1973-87 ball joint for proper fitment to this ProSpindle. Steering arm tie rod taper differs between 67-70 and 71-87 spindles.
