4" 2025 Ram 2500 4WD (w/Diesel Engine) Lift Kit w/Radius Arm by Zone

Give your RAM 2500 Diesel the stance, strength, and performance it deserves with the Zone Offroad's ZOND154F / D154N, a 4" Radius Arm Suspension Lift Kit. Engineered for precision and durability, this system lifts the front 4" and the rear 2.5", delivering a leveled, aggressive look while maintaining excellent on-road comfort and enhanced off-road capability. Perfect for work, adventure, or daily driving, this kit transforms your truck without overcomplicating installation.

The system features heavy-duty, high-strength radius arms designed to improve handling, durability, and caster control. Progressive-rate coil springs provide a smooth, controlled ride across any terrain, while a forged drop pitman arm corrects steering geometry for predictable handling. Track bar relocation brackets ensure proper axle alignment, and you can fine-tune your ride with your choice of Zone Nitro or Fox 2.0 Adventure Series shocks.

Designed for standard travel, this kit eliminates the need for a transfer case indexing ring or crossmember, simplifying installation while maintaining reliability. Tested across North America’s harshest conditions, this lift kit offers the perfect balance of ride quality, toughness, and capability for RAM owners who demand the best.
