Built for Ford Super Duty owners who want to run 35–37" tires without sacrificing factory ride quality, this 6-inch radius arm drop lift kit transforms your truck's stance while preserving suspension geometry. The kit includes precision-fit drop brackets, fabricated rear blocks, and a matched pair of M1 monotube shocks tuned for balanced on and off-road performance.

What's included

  • Radius arm drop brackets — Precision-fit to factory mounts, these maintain proper caster angle for correct handling and driveability while allowing the front to level with the rear.
  • Fabricated rear lift blocks — Stronger and longer-lasting than cast alternatives, designed with anti-axle wrap geometry to maintain stock ride quality.
  • Front CV driveshaft — Matches the truck's new suspension geometry and accommodates the increased ground clearance.
  • U-bolt kits (front and rear) — Factory-style fastening for secure component attachment.
  • M1 monotube shock pair (front and rear) — Valved for balanced performance on pavement and trails.
  • 6-inch coil spring kit — Works with the drop brackets to achieve the full lift height while preserving suspension angles.
