Fitment & Compatibility
The supplied table covers listed 2014–2023 Ram 2500 and 3500 front applications, in two- and four-wheel-drive configurations. Listed 3500 front coverage includes single- and dual-rear-wheel trucks; do not transfer this to a rear-kit claim. The 16.00 × 1.50-inch Spec37 GT rotor rings use separate hats and an eight-on-6.50-inch wheel pattern. Six-piston TX6R calipers use BP-22 pads. The specified front braided hose kit, 220-15672, is included. Check the stock upright, hub interface, hose routing and wheel drawing; the 20-inch minimum wheel guidance is not a guarantee that every wheel of that diameter clears.
Listed models: 2500; 3500. See the supplied table below for each year, submodel and equipment condition.
