Wilwood Front GM Six-Lug Truck/SUV Brake Kit (1999–2020), Black TC6 Calipers & 16-Inch SRP Rotors

The drilled/slotted 16-inch rotor option is supplied with black six-piston TC6 calipers for the qualified GM six-lug front applications. This package retains the original hubs and requires enough wheel space for the complete caliper-and-rotor envelope. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. It designs and manufactures disc brake components and complete systems, from calipers and brake rotors to valves, master cylinders, fittings and brake lines. Motorsport, street-performance and specialized installations each require those components to be matched to the complete brake system.

Avalanche and Escalade EXT have their own earlier end years; trim, police-package and generation restrictions still apply.

DS506 covers factory aluminum and iron spindles. Later casting parting lines may need light machining, and the lower dust shield requires trimming. Flexlines are separate: the instructions identify 220-8998 for 1999–2006 and 220-10980 for the later 16-inch arrangement; confirm the exact year and chassis connection before purchase.
