2017-2023 Powerstroke Rear Add-A-Pack Leaf Springs w/ 1" Lift (CS-FPAP-LVL-17)

Fits

Note: Progressive Add-A-Pack is NOT recommended for an F350

This 5-leaf progressive add-a-pack replaces your lower overload leafs in the rear with 6 thinner gauge springs that improve mobility of the springs, traction, predictability, and ride quality off-road and when you're hauling without compromising load capacity. Effectively eliminating the harsh rebound incorporated with factory springs.

Part Number: CS-FPAP-LVL-17

• Progressive design addresses the harsh rebound of the factory overload spring
• Includes bump stop drops, U-bolts, and hardware
• Pairs to Carli Leveling Lifts provides a ½-inch to 1" high rear stance
• Eliminates the factory block

• When it comes to the F350, the main spring pack in the rear is already quite stiff and does not compress much unless under load. As a result, installing the Add-A-Pack on an F350 may make the rear suspension stiffer, potentially even stiffer than the stock setup. For this reason, the Progressive Add-A-Pack is not recommended for an F350. To achieve optimal ride quality, we highly recommend installing Carli Full Replacement Leaf Spring Packs.
