Carli CS-F45-STR-05 4.5in Starter System | 2005-2007 F250/F350

The Super Duty Starter system is designed for people who want a suspension lift without the stereotypical ride-quality degradation associated with mass-produced “lift kits”. The IFP Bilstein 5100 shocks build quality is unmatched for their price point offer a nice boost in ride quality and carry a lifetime warranty through Bilstein.

The truck will sit 4.5” higher in the front and have more wheel travel thanks to the taller, Progressive Rate Coil Springs. Radius Arm Drop Brackets reset the pivot point and keep the travel linear for the best ride while Sway Bar Links or Drop Brackets reset the sway bar engagement point. Bump Stop Drops protect the shocks from over-compressing, the Adjustable Track Bar centers the front axle and Stainless Brake Lines firm up braking and ensure there is enough line for the newfound travel. To round off the front end, we include Caster Shims to tighten the steering.

The rear is outfitted with a Progressive Add-a-Pack. The 4.5” lift, Add-a-Pack equipped systems maintain payload capacity and are designed to work with trucks equipped with the factory 3-5/8” rear block. Super Duties equipped with a 2″ tall block from the factory will require the factory 3-5/8″ tall Block to achieve a leveled stance with the Add-a-Pack. Part Number: 7C3Z-5598-HB, 7C3Z-5598-JB

This system is considered entry level; however, it’s fully upgradeable and only requires an upgrade to one of our many signature tuned shock packages to be converted to one of the higher-end systems. This system was designed with the Progressive Add-a-Pack and should not be run with the Full Progressive Leaf Springs.
