The ReadyLIFT 6-inch Big Lift Kit for 2019-2024 Ram 3500 High Output Diesel trucks is an all-inclusive solution for owners seeking maximum height and refined performance. Featuring heavy-duty radius arm drop brackets and diesel-specific front coil springs, this system corrects vital suspension geometry for a "better-than-factory" feel. The kit includes a forged dropped pitman arm and a track bar relocation bracket to ensure precise steering and centered axle alignment, providing the necessary clearance for aggressive 37-inch off-road tires.
