Zone Offroad D103F 4-Inch Radius Arm Lift Kit with Adventure Gas Shocks and 2-Inch Rear Block

The Zone Offroad D103F is a 4-inch front radius arm suspension lift kit paired with a 2-inch rear block kit (without overload springs) for the 2019 Ram 3500 4WD. This Adventure Series kit is engineered to dramatically increase ground clearance, improve off-road capability, and allow fitment of larger tires — all while maintaining a controlled, confident ride.

The front lift is achieved through heavy-duty radius arms that correct caster geometry while delivering the full 4 inches of front lift. The kit includes Zone Offroad's Adventure Series gas shocks, which are designed specifically for lifted trucks to provide improved damping, ride comfort, and off-road performance over stock replacements.

The rear of the truck is leveled using a 2-inch rear block kit configured for Ram 3500 trucks without factory overload springs, ensuring correct block-to-axle fitment and a level stance front-to-rear.
