4" 2025-2027 Ram 3500 4WD (w/Gas Engine) Lift Kit (w/Radius Arms) by Zone

The Zone Offroad ZOND176N / ZOND176F 4-Inch Suspension Lift Kit for 2025-2027 Dodge Ram 3500 4WD diesel trucks is a complete radius arm suspension system that increases ground clearance, tire clearance, and overall suspension capability while maintaining controlled on-road handling. The system combines progressive-rate front coil springs, heavy-duty replacement radius arms, a front track bar relocation bracket, sway bar links, brake line brackets, rear lift blocks, extended U-bolts, and matched front and rear shocks. Rear lift options include 2-inch blocks with overload springs, 2-inch blocks without overload springs, 3-inch blocks with overload springs, or 3-inch blocks without overload springs. ZOND176N kits use Zone Nitro Series front and rear shocks, while ZOND176F kits use FOX 2.0 Adventure Series front and rear shocks.

Heavy-duty fabricated radius arms form the foundation of the front suspension system and are engineered to correct caster geometry at the increased ride height while providing the strength required for the heavy-duty diesel platform. Progressive-rate front coil springs support the additional weight of the Ram 3500 diesel while delivering controlled suspension response across changing road and trail conditions. A front track bar relocation bracket helps re-center the axle beneath the truck, supporting proper steering geometry and alignment, while extended sway bar links and brake line brackets accommodate the taller suspension configuration.

At the rear, high-strength fabricated lift blocks provide either 2 or 3 inches of additional ride height depending on the selected stance. Separate block configurations are available for trucks equipped with factory overload springs and trucks without overload springs, allowing the rear suspension hardware to match the original leaf spring setup. Longer U-bolts secure the lifted rear suspension, while matching rear shocks provide consistent damping performance from front to rear. The 4-inch suspension system provides clearance for up to 37-inch tires with properly configured wheels.

The ZOND176N configuration includes Zone Nitro Series front and rear shocks featuring nitrogen-charged twin-tube construction and 10-stage velocity-sensitive valving for responsive damping during daily driving, towing, and recreational off-road use. The ZOND176F configuration includes FOX 2.0 Adventure Series front and rear shocks with 2-inch steel monotube bodies, internal floating pistons, 5/8-inch hard chrome-plated shafts, high-flow pistons, and application-specific valving. With four rear block configurations and two complete shock packages, the ZOND176N / ZOND176F system can be matched to different factory spring setups, desired rear stance, and suspension performance requirements.
