4-Inch Lift Kit w/ Pro-Ride Coil Springs

The BDS Suspension 4-inch lift kit is engineered to enhance the stance, performance, and capability of your 2013-2018 Ram 3500 diesel-powered truck featuring factory rear air ride. This comprehensive kit provides the necessary components for a 4-inch lift, allowing for the fitment of up to 35-inch tires. It also includes high-strength tubular radius arms that replace the factory stamped steel arms, offering improved strength, handling, and caster adjustment. For steering correction, a forged drop pitman arm is included to minimize steering angle, along with a heavy-duty track bar drop bracket to re-center the front axle and maintain proper geometry through suspension travel. The rear of the vehicle is addressed with a high-strength fabricated lift block and a heavy-duty air bag spacer, paired with longer U-bolts. Both front and rear suspension systems can be outfitted with either BDS NX2 gas shocks or FOX 2.0 Performance Series IFP gas shocks, selected at the time of purchase, to further improve ride quality and off-road performance. Recommended tire and wheel combinations include 37 x 12.5 tires with 20 x 9 wheels (5.625-inch backspace) or 35 x 12.5 tires with 20 x 9 wheels (4.5-inch backspace). Note that some tire trimming may be required depending on the chosen setup.
