From Carli Suspension

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 spring designed to maintain the factory load capacity while increasing mobility of the spring. Improved traction and predictability are immediately noticeable and as is a much-improved ride off-road and when loaded.

The 1″ lift provided by this pack matches to our 3″ front systems.
