Zone Offroad D54 4.5" Radius Arm Suspension System 13-18 Ram 3500 6.7L Cummins 2013-2018 Ram 3500 6.7L Cummins 4x4

There's a big difference between your run of the mill "lift kit" and a legitimate "suspension system." This system from Zone definitely falls more in line with a suspension system as it takes into account all angles to not only lift your Cummins powered Ram, but also improve upon the performance of the suspension for an improved ride, on or offroad. With this kit, you'll be able to run up to 37" tires to separate your Ram from the crowd and allow you to venture anywhere!

Holding true to typical Zone form, this lift system is centered around two new massive radius arms to replace the factory arms. The new arms are fully boxed, internally gusseted and designed to bolt in the factory location while adjusting the suspension geometry for 4.5" to 6.5" of lift.

The arms utilize extra large, greaseable bushings at the frame and are designed to use the factory alignment cams at the axle. They are formed for maximum tire clearance. Lastly, they just flat-out look cool and are a nice upgrade from the standard radius arm drop systems.

In addition to the new radius arms, like other Zone Ram kits, this system gets progressive rate front coils, track bar relocation and steering correction. Out back there is a lift block and u-bolts to level everything out
