03-18 RAM 2500/3500 PROGRESSIVE ADD-A-PACK, 1" LIFT

The 5-Leaf Progressive Add-a-Pack Rear Springs replace the lower overload leaf on the factory spring pack (the 1″ thick leaf that doesn’t follow the contour of the rest of the pack) with 5 thinner gauge leaves designed to maintain factory load capacity while increasing spring mobility. Improved traction and predictability are immediately noticeable, along with a much-improved ride both off-road and when loaded.

• Replaces lower overload spring
