Carli Add-A-Pack Rear Leaf Springs - 2017-23 Ford F250/F350 4×4 - 3in Lift

With this Carli Add-A-Pack rear leaf spring kit, you get a six-leaf progressive mini-pack, a 2-inch block, bump stop drops, U-bolts, and all the necessary hardware to get the job done. This system is designed specifically for the 2017-2023 Ford F250 and F350 4x4 trucks, aiming to smooth out the ride by addressing the harsh rebound often felt from the factory overload springs.

The factory overload springs are typically a single, thick leaf that doesn't flex with the rest of the spring pack. Carli replaces this with a thinner, progressive six-leaf pack. This updated design means the spring rate becomes much more predictable, leading to a smoother engagement and disengagement as the suspension works. While the overall load capacity of your truck remains the same as determined by the factory springs, the way the rear suspension handles bumps, especially medium to large ones, is significantly improved. This results in a more comfortable ride and better traction.

This kit provides a 3-inch lift, which will give your truck a slightly rear-high stance when paired with a 4.5-inch or 5.5-inch lift system. It’s a well-built modification that focuses on refining the rear suspension's performance for everyday driving and hauling.
