ReadyLIFT 2.5" Front Coil Spring Lift Kit For 20–25 Ford F-250/F-350 SD 6.7L 4WD

ReadyLIFT’s 2.5" Coil Spring Front Lift Kit (PN 46-20252) is built specifically for 2020–2025 Ford Super Duty F250 and F350 4WD diesel trucks. This system enhances ground clearance and provides a more aggressive stance while maintaining factory ride comfort. It supports 35" tires, or up to 37" with trimming, and includes model-specific components like brake line brackets, bump stop extensions, and sway bar frame mounts to preserve suspension geometry and handling. Ideal for retaining factory shocks, the kit installs easily and provides reliable on- and off-road performance.

Tremor models will achieve approximately 1.125" of lift instead of the full 2.5". Trucks equipped with the factory Onboard Scale system will require the optional Auto-Leveling Headlight Bracket (PN 67-23210). In certain cases, retaining the factory track bar bracket may be necessary if the axle is off-center. For trucks with a single vacuum hub, ReadyLIFT advises avoiding the use of caster eccentrics and instead recommends using radius arm drops or ReadyLIFT radius arms for best alignment and handling results.

For best results, use radius arm drops or ReadyLIFT radius arms
