ReadyLIFT Suspension now offers its first 4" Coil Spring Lift Kit for 2017-2022 Ford Super Duty F250/F350 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/F350 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. These heavy-duty radius arms are engineered to withstand the rigors expected from Super Duty trucks and surpass factory radius arms with added support gussets. Their inward formation allows for increased tire clearance and the installation of oversized tires, all through a direct bolt-on design that ensures quick and easy installation. This optimal lift height accommodates tires up to 37" in height, delivering an exceptional ride and handling performance. The key components for improving your ride include specially engineered coil springs, Falcon shocks, and track bar relocation. This combination transcends a mere lift kit, offering both enhanced performance and ride quality on and off-road. The ReadyLIFT 4" Coil Spring lift kit for 2017-2022 Ford Super Duty trucks also includes model-specific brake line extension brackets, proven bump-stop extension brackets, and new front sway bar frame mount extension brackets to maintain the factory sway bar's correct position. If you seek a rugged appearance and a smooth yet controlled ride, the new Super Duty 4" Coil Spring Suspension Kit System is your answer.
