Product details

This eight-lug package supplies black TC6 calipers with 16-inch drilled/slotted rotors. The hats, brackets and pads are selected for the documented GM truck/SUV and H2 spindle arrangements rather than a generic heavy-duty axle. Wilwood Engineering designs and manufactures the disc brake systems and components used throughout its motorsport, street-performance and specialized product range. Bill Wood established Wilwood in 1977, and the company is based in Camarillo, California. Its calipers, brake rotors, valves, master cylinders, brake lines and fittings are selected according to the demands of the whole brake installation.

Fitment & Compatibility

Use only with the listed eight-lug GM truck/SUV and Hummer H2 applications. The Silverado/Sierra entries cover selected 1500HD, 2500/2500HD and 3500 trucks through 2010; Suburban 2500 and Yukon XL 2500 entries extend through 2013. Hummer H2 coverage is 2003–2009 and Avalanche 2500 is 2002–2006. Observe the exclusions for four-wheel steering and each individual chassis.

The 16-inch rotor package retains the factory hubs. DS508 requires the hub register and eight-lug pattern to match the hats and adequate bolt engagement after shimming. Separate hoses are specified as 220-8998 for earlier vehicles or 220-10980 for the later connection; verify year, routing and fitting type.

Check the full application table below, including its model-year splits and brake-configuration requirements.
