Product details
A 4.84-inch center register and eight-on-6.50-inch stud layout identify the Ram version of this 15-inch GT truck rotor. Its 1.50-inch friction section and 2.000-inch offset must match the corresponding TX6-DM front assembly. Wilwood’s calipers, rotors, master cylinders, valves, fittings and lines support complete disc brake systems rather than an isolated component choice. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures these systems for motorsport, street performance and specialized applications. Correct pairing of the rotor with its surrounding hardware is essential.

Fitment & Compatibility
