2003-2009 Ram 2500/3500 4x4 Diesel Full Progressive Leaf Spring Kit - 1in Lift

Why these springs

The rear springs on a heavy-duty truck are built for maximum load, which makes an empty truck ride harsh. Carli's rear leaf springs for 2003–2009 Ram 2500/3500 4x4 diesel change how the rear rides and sits, with 1″ of lift, and work with Carli's rear shocks and systems.

Who they're for

A good fit if you want a smoother rear ride or need the rear height to match a Carli front lift. Check the payload, air-ride and system notes below before ordering, since rear springs change how the truck carries weight.
