Product Details

The ReadyLift 4" Coil Spring Suspension System w/Falcon MAX3.3 Shocks And Radius Arms is made for the 2023-2026 Ford F-250 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!

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.
