4-Inch Lift Kit w/ Rear Air Bag Spacer

The BDS Suspension 4-inch Lift Kit with 4-Link is engineered to elevate your 2019-2024 4WD Gas Ram 3500 equipped with factory rear air bags. This comprehensive system is designed to significantly improve your truck's stance, performance, and off-road capability, providing clearance for tires up to 37 inches in diameter. Up front, the kit features BDS's Pro-Ride progressive rate coil springs for a balanced ride across various terrains. Heavy-duty tubular radius arms replace the factory stamped steel units, offering enhanced strength and caster adjustment. Steering geometry is optimized with a forged drop pitman arm and a track bar relocation bracket to ensure proper axle centering and alignment through the suspension's travel. The kit also includes components for sway bar and brake line relocation, as well as an HD transmission crossmember and transfer case indexing ring to correct driveline angles, allowing the use of factory front driveshafts. In the rear, the lift is achieved with a high-strength steel lift block and a heavy-duty air bag spacer. Buyers can choose between two premium shock options: the NX2 Nitro Series, featuring a nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving, or the FOX 2.0 Performance Series, which boasts a 2-inch impact-extruded aluminum body with an internal floating piston (IFP) monotube design for superior performance and heat dissipation. Recommended tire and wheel combinations include 35x12.50 with 20x9 wheels (4.5" backspace) or 37x12.50 with 20x9 wheels (5.625" backspace). Note that some trimming may be required for tire fitment. This kit is specifically designed for Ram 3500 models with factory rear air ride and gas engines.
