ReadyLIFT Suspension is pleased to announce A new Super Duty Suspension System. We are now shipping our 4 Inch Coil Spring Lift Kit, the new 4 Inch lifts features front and rear Falcon 2.1 Falcon shocks. This kit is designed to improve stance, performance, and capability and features everything necessary to clear larger wheels and tires. With vehicle-specific performance-tuned Falcon 2.1 dampers on all four corners, these lift kits provide a better-than-factory feel. Falcon Performance Shocks improve performance and comfort regardless of the terrain. The versatility of these systems makes them ideal for daily driving, off-road excursions, and tow/haul duties. 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.
