05-07 Ford F250/350 4x4 Progressive ADD-A-Pack

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 2005–2007 Ford F-250/F-350 4x4 change how the rear rides and sits, 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.
