Zone Offroad D143F 3-Inch Radius Arm Suspension Lift Kit with Fox Shocks

The Zone Offroad D143F is a complete 3-inch radius arm suspension lift kit engineered specifically for 4WD diesel Ram 3500 trucks. Designed to lift and level the stance, this system delivers improved on-road and off-road performance while providing clearance for up to 35-inch tires.

Progressive rate coil springs provide a smooth, controlled ride across all terrain types while supporting the added weight of the diesel platform. A heavy-duty track bar relocation bracket repositions the front axle to keep steering in phase for precise, predictable handling. This kit includes FOX Adventure Series IFP (Internal Floating Piston) monotube gas shocks at all four corners, delivering fade-free performance on and off the pavement. In the rear, a fabricated lift block and longer U-bolts level the stance and retain ride quality.

Key Features:

• 3 inches of front and rear lift for an aggressive, leveled stance
• High-strength boxed steel replacement radius arms correct caster and improve tire clearance
• Progressive rate front coil springs engineered for diesel platform weight
• FOX Adventure Series IFP monotube gas shocks for fade-free on- and off-road performance
