Carli Add-A-Pack Rear Leaf Springs 2011-16 Ford F250/F350 4X4 2in Lift

The Carli Progressive Add-A-Pack is engineered to improve rear suspension performance by eliminating the harsh rebound associated with the factory overload spring. Designed specifically for Super Duty trucks, this system replaces the lower overload leaf with a mini progressive 6-leaf pack, delivering a smoother and more controlled ride both on and off-road.

By maintaining factory load capacity while significantly improving spring rate progression, this upgrade enhances ride quality, traction, and overall suspension predictability. When paired with a Carli Suspension System, it effectively absorbs medium to large impacts for a more refined driving experience.
