ReadyLIFT Suspensions 4" Coil Spring Lift Kit, designed to fit 2017-2022 Ford Super Duty F250/F350 Powerstroke trucks, now equipped with new Tubular Radius Arms. This kit comes with front and rear Falcon 1.1 Monotube series performance shocks, accompanied by their reliable front track bar relocation bracket, tubular radius arms, and rear fabricated blocks. This offers a compelling option for lifting F250/F350 Super Duty trucks to accommodate larger tires, with the coil spring system allowing for increased tire sizes and widths while providing enhanced ground clearance for a head-turning stance. Many enthusiasts consider this lift height the 'sweet spot' for Super Duty driving dynamics, allowing for maximum tire size while maintaining everyday practicality.

The Radius Arms are specifically designed to fix suspension geometry on lifted models. These heavy-duty arms are built to withstand the demands placed on Super Duty trucks, surpassing factory radius arms with added support gussets. Formed inward for additional tire clearance and the installation of oversized tires, these arms provide robust performance. The direct bolt-on design ensures a quick and easy installation process.

This optimal lift height allows for the fitting of tires up to 37" tall. The coil spring kit not only delivers an excellent ride but also enhances handling performance. The key components for improving the ride are the specially engineered coil springs paired with Falcon shocks and a track bar relocation bracket. Beyond being a mere lift kit, this is a comprehensive performance and ride-enhancing kit that promises to delight consumers with its on-road and off-road capabilities.
