2013-2018 Ram HD 5.5" 4-Link Conversion Kit with NX2 Nitro Shocks (BDS1780H)

BDS 5.5" lift with 4-Link conversion for the 2013-2018 Ram 3500 gas truck with clearance for up to 37" tires. Up front it includes gas-specific Pro-Ride coil springs, 4-Link control arms with conversion mounts, a forged drop pitman arm and track bar bracket for steering correction, bump stops, brake line brackets, and precision tuned NX2 or FOX 2.0 nitrogen charged shocks. The 4-link converts the factory stamped steel radius arms over to high-strength 1/4" steel brackets that mount HD upper and lower control arms to correct axle positioning while limiting caster change through wheel travel. In the rear it uses a high-strength fabricated lift block, longer u-bolts, and matching NX2 Nitro or FOX 2.0 Performance shocks.
