2019-2024 Ram HD 4" 4-Link Conversion Kit with FOX 2.0 Performance Shocks (BDS1666FS)

Built to outperform, this BDS 4" lift kit with 4-Link conversion fits your RAM 3500 diesel, with clearance for up to 37" tires. Up front it includes diesel-specific Pro-Ride coil springs, heavy-duty replacement radius arms, a forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets, and precision tuned NX2 or FOX 2.0 shocks. The 4-link converts the factory stamped steel radius arms to correct axle positioning and limit caster change through wheel travel. At this height the transfer case is indexed using a supplied indexing ring and new transmission crossmember. The rear uses a high-strength fabricated lift block, longer u-bolts, and a matching set of NX2 Nitro or FOX 2.0 Performance shocks.
