Overview
This 4-inch radius arm lift kit from BDS Suspension is designed for 2019–2024 Ram 3500 4WD diesel-powered trucks. The kit improves stance, performance, and capability while providing clearance for up to 35-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, heavy-duty tubular replacement radius arms, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation hardware, and brake line brackets. To maintain use of the factory front driveshaft at this lift height, a transfer case indexing ring and new transmission crossmember are supplied. The rear of the kit utilizes a high-strength fabricated lift block, longer U-bolts, and a matched set of shocks. Select the configuration that matches your truck's rear suspension (with or without factory overload leaf springs), transfer case bolt pattern (6-bolt standard or 8-bolt Aisin), and preferred shock series.
