7″ Radius Arm System w/Coil Springs & Front Dirt Logic 2.25 Resi Shocks & Rear Dirt Logic Shocks – K3156DL



2014-18 Ram 2500 4WD

Fabtech’s new Coil Spring Suspension Systems for late model Ram 2500 trucks will provide a smoother on road ride than factory with the ability to handle heavy loads and rough offroad use.

As an industry exclusive Fabtech utilizes front coil springs with a straight spring design and patent pending angled lower mounts that produces a very smooth ride compared to stock. The factory springs are a high rate bowed style that naturally rides stiff with an overactive response to varying road conditions. Fabtech’s straight design has a lower spring rate that provides a smoother ride yet still retains the factory carrying capacity of the vehicle when required. No other Ram suspension system can offer this.

The Fabtech rear coil springs on 2500’s are a dual stage design. The first stage provides a supple ride quality when unloaded. The second stage provides the ability to handle factory carrying capacity loads when required giving the best of both worlds.

The combination of Fabtech’s front straight coil springs and rear dual stage coil springs will provide a noticeable ride quality improvement of the vehicle compared to stock.
