Product Details

Fabtech’s new coil spring suspension systems for late-model Ram 2500 trucks deliver a noticeably smoother on-road ride than the factory setup while maintaining the strength needed to support heavy loads and handle demanding off-road conditions.

As an industry exclusive, Fabtech equips the front suspension with straight-design coil springs and patent-pending angled lower mounts. This innovative combination produces a far smoother ride than the OE bowed high-rate springs, which naturally feel stiff and overly reactive on uneven terrain. Fabtech’s straight coil design uses a lower spring rate to enhance comfort while still retaining the truck’s full factory load-carrying capability—a benefit unmatched by any other Ram suspension system.

The rear coil springs utilize a dual-stage design. The first stage offers a soft, compliant ride when the vehicle is unloaded, while the second stage engages as needed to support full factory load capacity, delivering the perfect balance between comfort and strength.

Together, Fabtech’s straight-rate front coils and dual-stage rear coils provide a significant improvement in overall ride quality compared to the stock suspension, whether driving on pavement or off-road.

Our patented Radius Arms feature a full tubular structure strengthened by dimple die side plates with an adjustable alignment cam at the axle to allow caster adjustment. Front spring lift options includes 6 replacement
