Elevated Performance with Heavy-Duty 4-Link Control

Take your 2019–2024 RAM 3500 4WD diesel with rear overload leaf springs to new levels of capability and comfort with the BDS 1693H 6” 4-Link Lift Kit. The factory radius arms are replaced with a true 4-link system that enhances axle control, reduces caster change, and dramatically improves on-road handling and off-road articulation.

Engineered for Strength, Comfort & Compatibility

This BDS system includes ¼-inch steel 4-link brackets and heavy-duty upper and lower control arms, paired with Pro-Ride coil springs tuned for diesel performance. At 6" of lift, BDS addresses front driveline geometry with a transfer case indexing ring and reinforced transmission crossmember, maintaining OEM driveshaft usability.

Rear Lift & Matched Ride Quality

The rear lift setup features 5" fabricated steel blocks, extended U-bolts, and NX2 Nitro shocks to match front performance. This design maintains rake under load and complements the system’s increased suspension travel and strength.
