ReadyLIFT Suspension is pleased to announce exciting a series of all-new premium suspension systems for the Ford Super Duty.  We are now shipping our 4” Suspension systems with 2.1 Falcons or 3.3 Falcon shocks. The first 4” kits come with our front monotube Falcon 2.1 shock and rear adjustable 2.1 tow haul shock. The second premium kit (available soon) includes front and rear 3.3 Fast Adjust Dampers offer a wide range of adjustability for specific terrain and/or handling characteristics with two separate knobs to tune to your preference finished with premium tubular radius arms.  This gives Super Duty owners a superior 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 available all-new Radius Arms are designed to correct the suspension geometry on lifted models. These new radius arms are heavy-duty and built to handle the use and abuse demanded of Super Duty trucks. They hold up to the abuse and surpass the factory radius arms and support gusset specifications. The arms are formed inward, allowing for additional tire clearance and the ability to install oversized tires. The direct bolt-on design promotes quick and easy installation.

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 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.
