2.5" 2017-2026 Ford F450 4wd (w/Diesel Engine) Signature Series Lift System by Carli Suspension

This Carli Suspension CS-FLVL-450-SIGKIT-17 2.5-inch front leveling system for the Ford F450 4wd diesel models is a high-quality kit that will lift the front end while also improving ride quality and suspension performance.

This leveling system features 2.5-inch lift front coil springs with a slightly reduced multi-rate for better ride comfort. Paired with the coil springs are Carli Signature Series shock absorbers. These shocks use a 2" diameter body with Zinc plating and a clear coating for corrosion resistance. An internal reservoir with a 5/8" diameter hardened steel chrome-plated shaft is also featured. 

To keep the front axle centered properly an adjustable front track bar is included. In typical Carli fashion this bar has features that are not found in other track bars. This includes 3/8 inch DOM construction that allow for use of a 1" x 7/8" FK bearing heim joint with a huge 1" shank.

Required Sway Bar Selection—While Carli does not include a front sway bar correction in this kit, it is required to install this lift kit properly. The drop bracket kit works great as a more economical solution. However, for truck owners wanting a HUGE improvement in ride quality, the Carli Torsion Sway Bar is your solution and is an amazing upgrade. It is designed to allow the front suspension to move more freely without giving up control.
