Product Details

The ReadyLift 4" Coil Spring Lift Kit w/Falcon Shocks And Radius Arms is made for the 2017-2022 Ford F-350 Diesel 4WD, giving it more ground clearance and room for larger tires.

ReadyLIFT Suspension now offers its first 4" Coil Spring Lift Kit for 2017-2022 Ford Super Duty F250/F-350 4WD Power Stroke trucks equipped with new Tubular Radius Arms. This kit, designated as 49-27421, comprises front and rear Falcon 1.1 Monotube series performance shocks, a front track bar relocation bracket, tubular radius arms, and rear fabricated blocks.

It provides an excellent solution for lifting F250/F-350 Super Duty trucks to accommodate larger tires, with the coil spring system enabling increased tire sizes and widths while enhancing ground clearance. This lift height strikes the ideal balance for Super Duty driving dynamics and maximum tire size while retaining everyday practicality. The newly designed Radius Arms address suspension geometry correction for lifted models.
