Description
High-Performance Lift Kit. The ReadyLIFT 4-Inch SST 2.1 Coil Spring Suspension Lift Kit with Falcon 2.1 Shocks enhances vehicle stance, performance, and capability by providing a 4-inch lift. It is designed specifically for 4WD diesel trucks to improve handling, comfort, and off-road ability while accommodating larger tires up to 37 inches. This kit gives owners increased ground clearance and aggressive styling without compromising ride quality.
Durable Construction And Finish. The system features high-quality 4-inch coil springs paired with vehicle-specific Falcon 2.1 monotube shocks, which are tuned for dynamic roll control and low-speed damping. All components, including radius arm and sway bar drops, are engineered to maintain proper suspension geometry and finished with robust coatings to withstand harsh environments and corrosion.
Installation. Installation requires moderate skill and typically takes around 6.5 hours without including alignment or wheel mounting. This bolt-on lift kit requires no structural modifications but may require minor trimming of the front valance to fit larger tires.
Application. Specifically designed to fit 2017-2022 4WD 6.7L Powerstroke F-350 Super Duty SRW diesel trucks. Tremor editions will not achieve the full 4-inch lift height. Not recommended for 2WD, gas-powered models, or vehicles with single cab configurations without validated fitment.
