6" MAX3.3 coil spring suspension system with four Falcon 3.3 monotube shocks, tubular radius arms, and a Falcon dual steering stabilizer for the 2023-2026 Ford Super Duty F-250/F-350 Power Stroke diesel 4WD.

ReadyLIFT expands its industry-leading Super Duty lineup with the 6" MAX3.3 Coil Spring Suspension System, engineered for customers demanding premium ride quality, larger tire fitment, and daily drivability. Specially engineered coil springs pair with Falcon 3.3 Fast Adjust piggyback shocks for terrain-tuned, on-the-fly compression adjustability. Heavy-duty tubular radius arms correct suspension geometry and withstand Super Duty abuse, and the Falcon dual steering stabilizer adds control and confidence with oversized tires on the solid front axle. Installation is bolt-on with no cutting, welding, or fabrication required.
