Important Notes
- The carrier bearing drop is necessary for models equipped with the two-piece rear drive shaft.
- Some vehicles may require a rear driveshaft spacer kit 122007 to maintain adequate rear driveshaft engagement
Features & Benefits
- Heavy duty 4-link improve strength, handling and caster control
- Front high strength progressive rate coil springs for a great ride on any terrain
- Front track bar relocation bracket to re-position axle
- Forged drop pitman arm to correct steering angles
- Front sway bar correction to maintain handling performance
- HD transmission crossmember and t-case indexing ring to correct front driveline angles and allow use of factory driveshafts
- BDS NX2 gas or FOX performance series IFP gas shocks to improved ride and offroad performance
Built to outperform, BDS Suspension engineered a 6-inch lift kit with 4-Link conversion for your 2013-2018 RAM 3500 diesel powered truck that will surely impress. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 37" tires.
Up front the lift kit includes diesel-specific Pro-Ride coil springs, 4-Link control arms with conversion mounts, 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.
In the rear this kit utilizes a high-strength fabricated lift block, longer u-bolts and a matching set of NX2 Nitro or FOX 2.0 Performance shocks.
4-Link Conversion
Convert the factory stamped steel radius arms over to the BDS 4-link to optimize suspension geometry for better handling characteristics while adding strength and stability. This bolt-on upgrade utilizes high-strength 1/4-inch steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.
Pro-Ride Coil Springs
A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains.
Steering Correction
To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
