Progressive Add-A-Pack - 1" Lift

Manufacturer description: 17-26 FORD F250/350 4X4 PROGRESSIVE ADD-A-PACK - 1" LIFT

From Carli Suspension

These packs are designed to eliminate the incredibly harsh rebound of the factory overload spring they replace helping to tame the medium to large bumps when paired with a Carli Suspension System. The Progressive add-a-pack replaces the lower overload springs on the factory pack. This is the 1″ thick leaf that doesn’t follow the contour of the rest of the pack. In removing this spring “wall” and replacing it with a mini progressive leaf pack, the capacity of the truck remains unchanged, as it’s determined by the factory springs, while the progression of the rear spring rate becomes substantially more predictable.
