Transform your RAM 3500’s suspension with the BDS 1690FS 6" 4-Link Lift Kit, engineered for diesel-powered models with 6-bolt transfer cases and no rear overload leaves. This advanced suspension system replaces the factory radius arms with a true 4-link conversion, dramatically improving axle control, strength, and ride predictability—ideal for both daily driving and aggressive off-road use.
BDS replaces the weak factory radius arms with a pair of heavy-duty upper and lower control arms. Paired with ¼-inch steel 4-link brackets, the setup minimizes caster change throughout wheel travel, resulting in smoother articulation and more confident high-speed handling.
A set of diesel-specific Pro-Ride coil springs lifts the front end, offering stability and comfort across a wide range of terrain. In the rear, 5" steel lift blocks and extended U-bolts maintain ride height and load capacity. A transfer case indexing ring and crossmember are included to correct driveline angles at this lift height, ensuring the factory front driveshaft remains usable.
