The ReadyLIFT 8.5 inch Coil Spring Lift Kit for 2017-2022 Ford Super Duty Diesel trucks is a comprehensive performance overhaul designed to accommodate up to 40 inch tires. Featuring heavy duty tubular radius arms and a transfer case clocking ring, this system ensures that caster and driveline angles remain within optimal parameters. The inclusion of Falcon 1.1 performance shocks and a track bar relocation bracket provides a stable, confident driving experience, making it the ultimate choice for a high profile, heavy duty build.

Features

• Heavy duty tubular radius arms correct caster geometry and are formed inward to allow for maximum tire clearance.
• Driveline Indexing System (DIS) includes a transfer case clocking ring to optimize driveline angles and eliminate vibration.
• Falcon 1.1 Monotube performance shocks are specifically tuned for the weight and dynamics of the Power Stroke diesel engine.
• Forged dropped pitman arm and track bar relocation bracket ensure accurate steering response and centered axle alignment.
• Engineered front coil springs provide a full 8.5 inches of lift while maintaining factory ride comfort.
• Fabricated steel rear lift blocks and add-a-leaf components provide a leveled stance and retain towing capacity.
• Sway bar drop brackets and bump stop extensions ensure all suspension components function safely at full articulation.
• Extended brake line brackets allow for full travel without putting tension on the factory hydraulic lines.

Notes

• This kit is engineered specifically 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 radius arm replacement.
• Vehicle alignment and headlamp aim must be adjusted following the installation for safety.
• Significant trimming of the front valance and inner fender liners will be necessary for 38 to 40 inch tire clearance.

Compatibility Notes

• Fits 2017 to 2022 Ford F250 and F350 Super Duty 4WD Diesel trucks.
• Specifically designed for Single Rear Wheel (SRW) models only.
• Not compatible with gasoline powered trucks, 2WD models, or Dually (DRW) configurations.
• Tremor models will gain less than the stated 8.5 inches of lift over their factory height.

Tire Fitment

• Maximum Tire Diameter: 38 to 40 inches (depending on wheel offset and trimming).
• Recommended Setup: 38x13.50 tires on a 10 inch wide wheel with a -18 to -24 offset.
