BDS Suspension 6 Inch Lift Kit Ram 3500 4WD Diesel w/ Rear Air Ride (2013-2018)

Upgrade the stance and suspension capability of your truck with the BDS Suspension 6 Inch Lift Kit for Ram 3500 4WD diesel trucks equipped with factory rear air ride (2013–2018). Engineered to improve ground clearance, ride quality, and off-road capability, this premium suspension system delivers the strength and durability required for lifted heavy-duty trucks.

At the front of the system, diesel-specific Pro-Ride coil springs are used to provide the proper lift height while maintaining a smooth and controlled ride across a variety of terrain. Heavy-duty radius arm drop brackets help maintain proper suspension geometry and improve stability at the increased ride height.

To maintain proper steering geometry after lifting, the kit includes a forged drop pitman arm and heavy-duty track bar relocation bracket. These components keep steering angles aligned and help recenter the front axle throughout suspension travel.

Because this lift height changes driveline geometry, BDS includes a transfer case indexing ring and upgraded transmission crossmember to correct front driveline angles while allowing the use of the factory driveshaft.

For trucks equipped with factory rear auto-level air suspension, this kit uses heavy-duty rear air bag spacers, lift blocks, and longer u-bolts to properly raise the rear while maintaining air ride functionality. The system is paired with NX2 Nitro Series shocks to deliver improved ride control both on the road and off the trail.

With clearance for up to 37-inch tires, this BDS Suspension lift kit provides improved off-road performance, enhanced suspension travel, and a more aggressive lifted stance.
