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.
  • Testing fitting is highly recommended as tire manufacturer dimensions can vary significantly.

  • Construction: 2.125 inch 6061-T6 aluminum alloy shock bodies for high impact resistance and heat dissipation.

Very nice quality and appearance
Color: Beige
They were surprisingly stout and went together well. We had to return them because when we took them to where they would be used, they were too big to work in that location. Dang. But if we needed them in the future, I wouldn't hesitate to purchase them.

Good Multi-use Panels
Color: Grey
These panels were easy to assemble and stand sturdy. i will use them to block the sun when I am outside doing yard work in the heat. I'm sure I will find other uses for them too.

We threw it away
Color: Grey
This thing cannot stand on its own, the side bars bend since it is not sturdy enough to handle the material screens. After assembly, I was so mad at it, the pleasure of crushing it was better than returning it. I tryed to think of other ways to use it, but could not… i kept the screens, they are the strongest part of this thing. Very disappointing
