4-Inch Lift Kit with 4-Link Conversion

The BDS Suspension 4-inch lift kit with 4-Link conversion is engineered to significantly upgrade the stance, performance, and capability of your 2019-2024 Ram 2500 4WD gas-powered truck equipped with rear air ride. This comprehensive system replaces the factory radius arms with heavy-duty BDS 4-link arms and high-strength 1/4-inch steel brackets, optimizing suspension geometry for enhanced handling, strength, and stability while correcting axle positioning and limiting caster change. Steering geometry is corrected with a forged drop pitman arm and a heavy-duty track bar drop bracket to keep the front axle centered. A new transmission crossmember and transfer case indexing ring are included to address driveline angles at this lift height, allowing the use of the factory front driveshaft. In the rear, the kit incorporates heavy-duty rear air bag spacers, a track bar relocation bracket for proper axle alignment, bump stop extensions, and sway bar links. Buyers can choose between BDS NX2 Nitro Series shocks or FOX 2.0 Performance Series IFP monotube shocks to further improve ride quality and off-road performance. The NX2 shocks are nitrogen-charged, twin-tube designs with 10-stage valving, while the FOX shocks feature a 2-inch aluminum body, internal floating piston (IFP) monotube design, and application-specific valving. This lift kit is compatible with tire sizes up to 35 inches, with recommendations for 35x12.5 tires on 20x9 wheels with 4.5 inches of backspacing, or 37x12.5 tires on 20x9 wheels with 5.625 inches of backspacing. Some trimming may be required for optimal tire fitment. It is important to note that this kit is engineered specifically for gas-powered RAM 2500 models and is not compatible with diesel engines or models equipped with factory air suspension beyond the rear air bag setup.
