03-13 RAM 2500/3500 PROGRESSIVE ADD-A-PACK, 3" LIFT, DIESEL

Carli 5-Leaf Progressive Add-A-Pack Rear Springs – 4″ Lift

The 5 leaf progressive add-a-pack rear springs replace the lower overload leaf on the factory leaf spring pack (1″ thick leaf that doesn’t follow the contour of the rest of the pack) with 5 thinner gauge leaf springs designed to maintain the factory load capacity while increasing mobility of the spring. Improved traction and predictability are immediately noticeable, as is a much-improved ride off-road and when loaded.

The 4″ lift provided by this pack matches to our 6″ front systems.
