The Carli Signature Leveling System, part number CS-FLVL-SIG-17, is an entry-level suspension upgrade for 2017-2022 Ford F-250 and F-350 Super Duty 4x4 diesel trucks. Designed for drivers who want improved ride quality, increased wheel travel, and a foundation for future suspension upgrades, this system provides a balanced combination of performance, comfort, and durability. The kit supports a 2.5-inch or 3.5-inch lift configuration depending on the selected leaf spring option, making it a versatile choice for daily driving, towing, and off-road use.
The system includes a front and rear shock package, linear-rate coil springs, brake line kit, bump-stop drops, caster-correction shims, and an adjustable track bar. Carli Signature Series shocks are specifically tuned by Carli to complement the suspension system, helping deliver controlled handling and a comfortable ride over varied terrain. Their corrosion-resistant construction is designed for long-term durability in demanding driving conditions, while the limited lifetime warranty provides added confidence for future upgrades and continued use.
Leaf springs are required and must be selected separately: CS-FPAP-LVL-17, CS-FFSP-LVL-17, or CS-FFSP-LVL-17-HD. With the appropriate leaf spring configuration, the system increases usable wheel travel to approximately 9 inches at the front and 13 inches at the rear. This suspension package fits 2017-2022 Ford F-250 Super Duty and Ford F-350 Super Duty 4x4 diesel models. Professional installation is recommended to ensure proper suspension geometry, alignment, and component performance.
