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 high performance vehicles. High capacity braking from the AERO4 radial mount calipers, High friction BP compound pads, and oversized 14.00" 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 and all others with increased brake requirements.

Wilwood Engineering designs and manufactures high-performance disc brake systems. Since the company’s inception in 1977 by Bill Wood, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Our core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motorsports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles. Wilwood has on-shelf stock of more than 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Wilwood off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment to heavy-duty original equipment brakes for the U.S. military Humvee.
