Wilwood AERO4 Front 14.25" Big Brake Kit w/ Slotted Rotors & 4 Piston Black Calipers

*Fits: 2014-2018 Chevrolet Silverado 1500

AERO4 Big Brake rear axle kits replace the factory disc brakes and use the OE parking brake assembly as a compliment to front big brake upgrades on late model trucks. High capacity braking from the AERO4 calipers, BP-10 compound pads, and oversized rotors are matched to the OE master cylinder output, ABS function, and individual vehicle bias requirements. Enhanced brake performance, increased durability, and high-tech style compliment big wheel, tire, and suspension upgrades on customized vehicles, tow rigs, and all others with increased brake requirements from high GVW. *Brake lines will need to be purchased.
