This kit is configured with NX2 Nitro Series nitrogen-charged shocks front and rear, providing a smooth, controlled ride on and off the pavement.
This 4-inch radius arm lift kit from BDS Suspension is designed for 2013–2018 RAM 3500 diesel-powered trucks equipped with factory rear air ride. The kit improves stance, performance, and capability while providing clearance for up to 35-inch tires. Up front, it includes diesel-specific Pro-Ride coil springs, heavy duty tubular radius arms, a forged drop pitman arm, a track bar drop bracket for steering correction, bump stops, and brake line brackets. In the rear, the kit uses a high-strength fabricated lift block, a heavy duty air bag spacer, longer u-bolts, and a matched set of shocks.
A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs provide the correct lift height and smooth, predictable ride across various terrains.
In place of the factory stamped steel radius arms, BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights, along with an OE-style rubber bushing at the frame mount for smooth, quiet, service-free operation.
A forged drop pitman arm minimizes steering angle after lifting. A heavy duty track bar drop bracket keeps steering geometry in phase through suspension travel while recentering the front axle.
The carrier bearing drop is necessary for models equipped with a two-piece rear drive shaft. Some vehicles may require rear driveshaft spacer kit 122007 to maintain adequate rear driveshaft engagement.
