Carli 08-10 Ford F250/350 SD Progressive Add-A-Pack

The Carli Progressive Add-A-Pack is designed to improve rear suspension performance by replacing the factory overload leaf with a six-leaf progressive spring pack. This upgrade eliminates the harsh engagement of the factory overload while maintaining the truck’s original load capacity.

By utilizing thinner, progressive leaves, the system delivers a smoother, more controlled ride and better absorbs medium to large bumps. The result is improved ride quality, enhanced traction, and more predictable suspension behavior both on and off-road.
