Product Details

The ReadyLift 4" Coil Spring Suspension System w/Falcon MAX3.3 Shocks And Radius Arms is made for the 2017-2022 Ford F-350 4WD.

ReadyLIFT Suspension is pleased to announce a new Super Duty lift kit. We are now offering our first 4" Coil Spring Kit including Tubular Radius Arms, Falcon Dual Steering Stabilizer and the new Falcon 3.3 piggyback shocks. This gives Super Duty owners an excellent alternative for lifting their trucks to fit larger tires. The coil spring system allows for increased tire sizes and widths along with providing improved ground clearance on a head-turning stance!

This optimum lift height allows for up to 37" tall tires. The coil spring kit delivers a great ride and handling performance! The key ingredients to improving Super Duty ride and handling are the new, specially engineered coil springs teamed with Falcon 3.3 shocks and a track bar relocation bracket!
