Is This for You?

This kit is for the 2009–2013 Ram 2500 4WD diesel owner who wants 6 inches of lift with FOX 2.0 damping. This is the DS-generation Ram 2500 diesel platform. If you have a 2014 or newer Ram 2500, stop here — different platform, order SKU 1660FS or 1660FPE. If you have a 2008 or earlier Ram 2500, stop here — order SKU 680FS or 681FS for 2008, or SKU 236FS/266FS for 2003–2007. If your Ram 2500 is gas, stop here — different kit required. Does not fit Ram 3500.

The Result

6 inches of front lift via diesel-tuned coil springs and geometry-correct radius arm correction brackets, with matched rear lift via replacement leaf springs and a 4-inch axle block — engineered for the 2009–2013 Ram 2500 diesel platform. The truck clears larger tires, sits aggressive, and maintains consistent geometry under diesel towing loads. FOX 2.0 shocks deliver improved damping over factory at this lift height.

Wheel & Tire Fitment

At 6-inch lift on the Ram 2500 diesel platform, typical fitment runs 37–40-inch tires depending on wheel offset and backspacing. Confirm maximum tire diameter and wheel specs with your wheel/tire supplier before ordering.
