2017-2026 Superduty Progressive Add-A-Pack - 3" Lift (CS-FPAP-45-17)

Description

Designed and built in conjunction with Deaver Spring MFG, these Carli Add-A-Pack Leaf Springs eliminate the use of your lower overload leaf, giving you thinner gauge leaves that improve mobility of the springs, traction, predictability, and ride quality off-road and when you're hauling without compromising load capacity.

Part Number: CS-FPAP-45-17

Features

• Progressive design addresses the harsh rebound of the factory overload spring
• 3" lift provides slightly rear-high stance with 4.5" and 5.5" lifts
• Load capacity is maintained, and ride quality is improved

Notes

• 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 actually 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
