Wilwood AERO4 RearTruck Kit 14.25in Drill Red 1999-2010 GM 1500-SUV 2 Piston OE Caliper - 140-9838-DR

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 and SUV’s. 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.
