2017-2022 Superduty 8.5" Lift Kit Falcon Shocks (49-27850)

The ReadyLIFT 8.5 inch Big Lift Kit for 2017-2022 Ford Super Duty Diesel trucks is a flagship suspension system that allows for the fitment of massive 38 to 40 inch tires. This kit features heavy duty radius arm drop brackets and a forged dropped pitman arm to correct suspension and steering geometry for a factory like feel. To handle the increased lift height, the system includes a transfer case clocking ring and a heavy duty transmission crossmember to optimize driveline angles, while Falcon 1.1 performance shocks provide superior damping and roll control.

Features

• Radius arm drop brackets maintain factory caster geometry for stable and predictable steering.
• Driveline Indexing System includes a transfer case clocking ring to optimize pinion angles and prevent vibration.
• Falcon 1.1 Monotube performance shocks are specifically tuned for the weight of the Super Duty diesel platform.
• Forged dropped pitman arm and track bar relocation bracket ensure accurate steering and centered axle alignment.
• Engineered front coil springs provide a full 8.5 inches of lift while maintaining a comfortable ride.
• Fabricated steel rear lift blocks and add-a-leaf components provide 7 inches of rear lift for a level stance.
• Heavy duty 3/16 inch plate steel front skid plate protects the differential and underbody components.
• Extended brake line brackets and sway bar drops ensure all components function safely at full articulation.

Notes

• This kit is designed for Ford Super Duty trucks equipped with the 6.7L Power Stroke Diesel engine.
• Professional installation is highly recommended due to the complexity of the transfer case clocking and geometry corrections.
• Vehicle alignment and headlamp aim must be adjusted following the installation for safety.
• Trimming of the front valance and inner fender liners will be necessary for 38 to 40 inch tire clearance.
