4-Inch Lift Kit with 4-Link Conversion

The BDS Suspension BDS1776FPE Performance Elite Lift Kit provides a 4-inch lift for the front and a 2-inch lift for the rear of 2013-2018 RAM 3500 diesel trucks, designed to enhance performance, stance, and off-road capability. This kit enables the fitment of up to 35-inch tires. The kit features a 4-Link conversion for the front suspension, replacing the factory radius arms to optimize suspension geometry, improve handling, strength, and stability. This bolt-on upgrade uses 1/4-inch steel brackets for HD upper and lower control arms, correcting axle positioning and limiting caster change. The front includes diesel-specific, progressive rate Pro-Ride coil springs for a smooth and predictable ride. Steering geometry is optimized with a forged drop pitman arm to minimize steering angle and a heavy-duty track bar drop bracket to re-center the front axle and keep components in phase during suspension travel. Included in the front are bump stops, brake line brackets, and your choice of BDS NX2 gas or FOX 2.0 Performance Series IFP gas shocks. The rear utilizes a high-strength fabricated lift block and longer u-bolts, paired with a matching set of NX2 Nitro or FOX 2.0 Performance shocks. Installation is rated as moderate and is estimated to take 10 hours, requiring tools such as a unibit, step drill bit, drill puller, pitman arm puller, and a welder. A notes section indicates that a carrier bearing drop kit is necessary for models equipped with a two-piece rear driveshaft.
