The unsung hero of the Carli suspension lineup, the Signature Series suspension system packs an unbeatable improvement in ride quality per dollar spent. The heart of this system is the custom spec Carli Signature series shocks. These shocks are made by Carli with vehicle specific valving profiles, ti-nitride coated shafts, zinc plated and clear coated bodies, and included shock boots. In this system, they're paired with Carli's vehicle specific coils, which are available in both diesel and gas specs for 2017 and newer Ford Super Duty trucks.

This system levels the truck, increases front wheel travel to 9" and dramatically smooths ride on road and off road. To support that height and wheel travel increase, Carli includes a host of the highest quality USA made supporting parts like their stainless brake lines, caster shims to address caster specs, and their in house designed track bar. Carli's track bar centers the axle at the new ride height utilizing a stronger suspension/steering link to prevent death-wobble and improve overall tracking and steering feel.

While it isn't mandatory to add a rear option, we do recommend the add a pack for F-250 trucks to eliminate the factory block, and improve ride quality on large impacts without sacrificing payload. If you don't add a rear Carli leaf spring option, certain 2020+ F-250s may need a taller rear block to sit level depending on the trim package. We recommend this block for trucks with a two piece driveshaft and this block for trucks with a one piece driveshaft.
