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.
