Wilwood Rear TX6R Brake Kit, Black with 16-Inch GT Rotors and Hoses, Ram 2500/3500 (2019–2023)

Ram 2500 and 3500 rear brakes receive black six-piston TX6R calipers and 16-inch GT rotors. Verify single rear wheels and dust-shield clearance. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. Wilwood designs and manufactures disc brake systems along with calipers, rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications each call for components matched to the overall braking arrangement.

Fitment & Compatibility

Listed for 2019–2023 Ram 2500 and single-rear-wheel 3500 rear brakes. The Ram 2500 trim and year rows below are specific: for example, Lone Star coverage is not a continuous range. Verify the installed axle and rear-wheel configuration. DS-1591 requires trimming the factory dust shield for the larger caliper and brackets. Check the full 16-inch rotor and TX6R wheel envelope, then route the supplied hoses clear of moving parts.
