2023 Ford Super Duty 4.5" Complete Suspension Systems with Gas & Diesel Specific Applications
.jpg)
The ICON Vehicle Dynamics presents our comprehensive array of 4.5" Complete Suspension Systems for 2023 Ford F250 & F350. ICON has optimized spring rate, ride height and valving to the specific needs of the gas and diesel engine versions of these trucks. The Systems are arranged in 9 Stages with variations for Gas or Diesel Coil Spring or Coilver Conversion, along with two optional upgrades for our Radius Arms and/or rear leaf Expansion Packs, for a total of 78 different system configurations to meet virtually any budget or performance goal.
Please read through the following information to learn more about Stages 1 through 9 and their variations
ICON SUSPENSION SYSTEM STAGES
Stage 1 through 8 Suspension Systems for Ford Super Duty feature upgraded, ICON-engineered dual rate front coil springs to provide 4.5 inches of front end lift-height and superior performance over stock, without using coil spring spacers (Stage 9 is only available in Coilover Conversion variation). Basic kits include radius arm drop brackets, rear leaf spring blocks and extended brake lines. Kits are available for either Gas or Diesel equipped trucks to optimize performance based on the difference in engine weight.

To fully realize the suspension performance potential of these trucks, ICON Coilover Conversion Systems delete the stock coil spring and shock configuration in favor of ICON 2.5 VS Series Coilovers to achieve better travel, damping and suspension system packaging.
4-LINK FRONT SUSPENSION SYSTEMS
Stages 6 and up are available with ICON's 4-Link Front Suspension System, including our heavy duty 4-link bracket kit along with upper and lower links with on-the-vehicle adjustability.

UPGRADE: EXPANSION PACK SYSTEMS
ICON's FSD Expansion Pack is a desirable upgrade to any of the Stages. This kit modifies the stock rear leaf springs to provide suspension height without lift blocks, and with superior rear suspension performance.

NOTE: All components of these Stages are also offered individually.
Suspension System Stages
STAGE 1 SUSPENSION SYSTEMS
ICON Complete Suspension Systems for Ford Super Duty begin at Stage 1, featuring ICON Dual Stage Front Coil Springs and 2.0 Series Shock Absorbers (or 2.5VS Coilovers on Coilover Conversion Systems). Rear shocks are ICON 2.0 Series Internal Reservoir Shocks. This basic kit provides 4.5" of front-end lift while improving ride and handling over stock.
