03-13 Dodge Ram 2500 / 03-18 Ram 3500 Diesel Progressive Add-A-Pack 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 add-a-packs for 2003–2013 Ram 2500 and 2003–2018 Ram 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.
