Built to outperform, BDS Suspension engineered a 4-inch lift kit with 4-Link conversion for your 2014-2018 RAM 2500 gas powered truck that will surely impress. Works on trucks with factory rear air ride option. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35" tires.

Up front the lift kit includes gas-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 heavy duty air bag spacers, track bar relocation bracket to correct axle positioning, bump stop extensions, sway bar links and a matching set of NX2 Nitro or FOX 2.0 Performance shocks. BDS also supplies new air ride leveling sensor brackets to re-position the ride height sensors allowing it to perform just like it does at factory ride height and maintain full air bag range of motion.

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, gas-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.

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.
