Carli 2.5" 2017+ F450 Signature Level System
2017-2024 Ford F450 SuperDuty Signature System
The Carli SignatureLeveling System was designed for people seeking a leveled vehicle with more performance and ride quality than a generic spacer lift. The included, front, Carli Signature Series Shocks are longer to accommodate the extended travel. When designing the shocks, Zinc plating, Clear Coat for corrosion resistance and quality bushings were a must; finished off with boots to protect the shafts, we back them with a limited lifetime warranty to ensure their quality is as unbeatable as their ride quality at this price point.
The truck will sit 2.5” higher in the front and have more wheel travel thanks to the lighter rate Carli Coil Springs. 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 and a fabricated, High-Clearance Bump Stop Drop to keep the springs clear from the contacting the factory bump stop. The front Sway Bar Geometry will need to be addressed with your choice of a Sway Bar Drop Bracket (more economical, maintains the factory Sway Bar End Links) or our Extended Sway Bar links with relocation brackets – a FAR more robust option. For those seeking the most possible ride quality, we offer our full replacement Torsion Sway Bar that lightens the most neglected spring rate – the factory sway bar. From the Torsion Sway bar upgrade, one can expect a far more compliant feel and increased articulation with only slightly more body roll.
Wheel and Tire: Factory Wheels SHOULD NOT be run with oversized tires. They’re known to rub the radius arm, sway bar and most concerning – Brake Lines. Factory tires and factory wheels will work without issue but we DO NOT recommend running oversized tires on factory wheels. On our 3.5” Ford Systems, we recommend 17”-18” wheels, no more than 9” wide with 5.5” of backspacing with Carli Fabricated Radius Arms or 5” Backspace with factory arms; 5” will require a bit more trimming. Tires, 37×12.5” will fit with some trimming; 35” will likely fit without trimming. The more rubber, the better the small bump compliance will be at proper inflation pressures. The ride will firm up as you go larger in wheel diameter. For more details, see our article on wheel and tire selection and tire pressures:
