Black TX6-DM rear calipers pair with 15.50-inch rotors for Ford F-250 and F-350 Super Duty. Check 4WD, single rear wheels and dust-shield work. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized applications require individual components matched to the complete brake system.

Fitment & Compatibility

Check the rear axle and single-rear-wheel arrangement on the listed 2023–2025 F-250/F-350 Super Duty 4WD before selecting this black TX6-DM package. Its 15.50 × 1.38-inch rear rotors are different from the 15-inch front kit. DS-1599 requires trimming the factory dust shield to clear the caliper bracket; allow for that work before installation. The supplied braided hoses must reach the hard lines without tension through suspension travel. Verify both wheel spokes and barrel with the full drawing, even when the wheel is nominally 20 inches. Exact vehicle rows remain in the table below.
