BDS 4" 4-Link conversion lift kit for the 2019-2024 Ram 3500 diesel with factory rear air bags, clearing up to 35" tires. The front converts the factory stamped steel radius arms to a BDS 4-link with HD upper and lower control arms on 1/4" steel brackets to optimize geometry and limit caster change, plus diesel-specific progressive-rate Pro-Ride coil springs, a forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, and brake line brackets. A t-case indexing ring and new transmission crossmember let you keep the factory front driveshaft. The rear runs a high-strength fabricated lift block, heavy duty air bag spacers, and longer u-bolts.
