Fitment & Compatibility

Rear coverage is limited to the listed 2014–2018 Ram 2500/3500 configurations. The 3500 entries are single-rear-wheel applications only; a front kit's dual-rear-wheel coverage does not extend to this rear package. One-piece 16.00 × 1.38-inch iron rotors incorporate the parking-brake hats and retain the original parking mechanism. The rear TX6R calipers use BP-22 pads, and rear hose kit 220-15676 is included. Modify the backing plate/dust shield for caliper clearance as DS-1292 specifies. Check the eight-on-6.50-inch interface, original parking hardware and the wheel template.

Listed models: 2500; 3500. See the supplied table below for each year, submodel and equipment condition.
