Peterbilt 379 Leaf Springs, Hangers & Acc.

Peterbilt 379 Replacement Leaf Spring Kits

If you’re looking for a performance upgrade for your aging, classic Peterbilt truck, consider these parts. You can experience stronger load support across your axles and, similar to your semi truck’s shocks, impact absorption from uneven roads or bumps and potholes on the highway. A solid set of aftermarket leaf springs can also contribute to stronger turn control and dampening (inter-leaf friction). New leaf spring hangers can ensure secure attachment points to your Peterbilt 379 frame and allow for smooth transfer of load forces. For a complete front-end upgrade, consider adding related steering components. While we don’t offer complete Peterbilt 379 steering column rebuild kits, we do sell critical steering components like drag links, cross tubes, bushings, and tie rods.
