The Wilwood AERO6 front big brake kit upgrades 1963 to 1987 Chevrolet and GMC C-series trucks running Wilwood Pro Spindles with six-piston red forged aluminum calipers and slotted 14.00 inch two-piece rotors. Each GT Spec-37 iron rotor measures 1.25 inches thick on an aluminum hat with a directional staggered vane face for sustained cooling under towing and heavy loads. BP-20 compound pads deliver fade-resistant stopping power while retaining OE master cylinder output and ABS function. Wheels 18 inches or larger are required for caliper clearance.
