Overview
This 4-inch radius arm lift kit from BDS Suspension is designed for 2019–2024 Ram 3500 4WD diesel-powered trucks, providing improved stance, performance, and capability with clearance for up to 35-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, heavy-duty replacement radius arms, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation, and brake line brackets, along with precision-tuned nitrogen-charged shocks. A transfer case indexing ring and new transmission crossmember are supplied to allow use of the factory front driveshaft at this lift height. In the rear, the kit uses a high-strength fabricated 2-inch lift block, longer U-bolts, and a matching set of rear shocks.
