Product Description

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.

These Wilwood W4A rear disc brake kits are designed to replace the factory disc brakes and still use the OEM parking brake assembly. They feature Wilwood's W4AR brake calipers, vented rotors, and BP-10 compound brake pads. Stop your ride quicker than ever before with one of these Wilwood W4A rear disc brake kits.
