The Carli Suspension 2" Progressive Add-A-Pack Leaf Springs CS-FPAP-05 improve drivability with the new lift kit in your Ford F-250/350 Super Duty. The lower overload leaf is removed and is replaced with thinner gauge leaves. The OEM. load capacity is maintained while improved ride is achieved.
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. The engagement and disengagement of the spring becomes quite a bit smoother increasing both ride quality and traction. As the "wall" was removed, the rear may sit lower with a heavy load BUT it will ride better loaded.
If Pairing to 4.5" System: Super Duty Trucks equipped with a 2" tall block from the factory will require the factory 3-5/8" tall Block to achieve a leveled stance to a 4.5" kit with the Add-a-Pack.
Factory Block Part Number: 7C3Z-5598-HB, 7C3Z-5598-JB
If Pairing to 2.5" System: Super Duty Trucks equipped with a 3-5/8" tall block from the factory will require the factory 2" tall Block to achieve a leveled stance to a 2.5" kit with the Add-a-Pack.
