49-23421 | ReadyLift 4 Inch Suspension Lift Kit With Falcon 1.1 Shocks and Radius Arms (2023-2024 F250, F350 Diesel)

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 and Falcon Dual Steering Stabilizer, #49-23421. The new 4” lifts include front and rear Falcon 1.1 Monotube series performance shocks with our venerable front track bar relocation bracket, tubular radius arms or radius drops, and rear fabricated blocks. 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!  Many consider this lift height the ’sweet spot’ for Super Duty driving dynamics and maximum tire size while maintaining everyday usefulness.

The all-new Radius Arms are designed to correct the suspension geometry on lifted models. These new radius arms are heavy duty and are built to handle the use and abuse demanded out of Super Duty trucks. The new radius arms hold up to the abuse and surpass the factory radius arms and support gussets. The arms are formed inward, allowing for additional tire clearance, and providing the ability to install oversized tires. The direct bolt-on design promotes quick and easy installation.

With the help of Falcon steering dampers in the 49-23421, ReadyLIFT’s new Dual Steering Stabilizer provides superior truck stability which is crucial for any solid front axle vehicle equipped with oversized-sized tires. Falcon steering stabilizers allow for more confident handling over the road and in challenging terrain. They reduce bump steer and improve steering feed contributing to overall truck comfort and security thanks to the increased truck maneuverability and control.

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 1.1 shocks and a track bar relocation bracket! This combination is more than just a lift kit, this is a performance and ride-enhancing kit that will really delight consumers with how well it rides and performs both on and off-road.
