Product details
An anodized body and 11.22-inch lug centers identify this left front Wilwood TX6-DM for the earlier GM heavy-duty conversion. Six differential stainless pistons operate over a nominal 1.50-inch-wide rotor in the specified GM 2500/3500 2011–2019 arrangement. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components. Bill Wood founded the company in 1977; its motorsport, street-performance and specialized range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Compare the current conversion's rotor, hoses and mounting geometry with the package instructions. Verify the 15.00-inch friction diameter and full wheel-clearance drawing; caliper side and truck year alone are not sufficient fitment checks.
PMB Performance brings over 20 years of experience to brake-component selection. Share the installed caliper, rotor size and mounting arrangement so the relevant dimensions can be compared.
