Product Description

The Wilwood 140-10776-DR kit equips vintage GM C10/C15/R10 trucks, Suburbans, and GMC Jimmys (1963-1987) with modern, high-performance braking. Featuring forged red FNSL6R six-piston radial calipers and 14" drilled/slotted Spec-37 rotors, this system delivers improved stopping power and heat management while maintaining factory-style brake bias with drop-spindle setups.

Engineered exclusively for use with CPP or Ridetech 2" drop spindles, the kit fits directly to existing setups using 5-lug hubs. The rotor hats have 1.62" offset and require 17"+ wheels for clearance. Installation is direct bolt-on with included hardware and performance BP-10 brake pads. Note: only front axle; no rear or parking brake feature included. Fitment is officially confirmed through 1987; any model year beyond that must be verified separately.
