F250 / F350 2017-2024 Ford 4WD (Diesel engines w/3.5"-4.0" axle tube) 3" Full Progressive Rear Leaf Spring Kit by Carli Suspension

These Carli CS-FFSP-17 Full Progressive Rear 3 inch Leaf Springs for the F250 / F350 are manufactured by Deaver Spring Mfg, in exclusive partnership with Carli Suspension. This innovative design offers a significantly more predictable and comfortable ride, with only a minor decrease in standard 3/4-ton load capacity. Unlike factory leaf spring packs, which typically feature 2-4 heavy main springs and an unyielding lower overload, our solution consists of a 9-Leaf main pack and a 3-Leaf overload, providing a more progressive spring rate. This results in a smoother unloaded ride, increased suspension travel, and impressive load-bearing capabilities as the rear end compresses, engaging all the springs.
