Wilwood Front Red TC6 Conversion with Drilled/Slotted 16-Inch Rotors for GM Six-Lug Trucks & SUVs (1999–2020)

Red TC6 calipers distinguish this GM front conversion, which includes 16-inch SRP iron rotors and application-specific hats. Later spindle castings and the original dust shields may require the modifications documented in DS506. 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

For the qualified six-lug Chevrolet, GMC and Cadillac truck/SUV applications below. Coverage includes Silverado/Sierra 1500 through 2018 plus the specified 2019 LD/Limited carryover models, and listed Tahoe, Suburban, Yukon, Yukon XL and Escalade variants through 2020. 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.

The table below gives the detailed vehicle coverage; match the individual entry and each referenced note.
