Fox 2017-2024 Ford F-250/F-350 Super Duty 4-6in Lift Rear 2.5 Performance Series Smooth Body IFP HTO Shock

Upgrade your Ford Super Duty with the Fox 987-24-021 rear shock designed for 4-6 inch lift kits on 2017-2024 F-250 and F-350 models. This 2.5 inch smooth body shock with Internal Floating Piston (IFP) extends wheel travel for off-road capability while delivering precise valving for on-road stability and reduced sway. Race-developed components ensure consistent damping in harsh conditions.

Key Features

  • Extended Travel Design: Increases drop-out travel in most applications to handle rough terrain without bottoming out
  • Performance Valving: Tuned specifically for Ford Super Duty ride dynamics offering connected feel and less body roll on pavement
  • Fade-Resistant Construction: Aluminum body dissipates heat four times faster than steel plus race-proven main piston and true IFP separating oil and gas
  • Smooth Body Technology: 2.5 inch diameter aluminum reservoir reduces harshness and provides 12.27 inches of travel (extended 30.05in compressed 17.78in)
  • Durability Built In: Torture-tested corrosion-resistant finish fully serviceable for long-term reliability in extreme environments

Product Notes

  • Confirm your lift height is 4-6 inches before purchase for proper fit
  • Shocks arrive pre-assembled and nitrogen-charged ready for install
  • Handle with care during transport to protect eyelet mounts

Installation Notes

  • Professional installation recommended.
  • Requires existing 4-6in suspension lift kit on vehicle
  • Eyelet-to-eyelet mounting with 0.50in diameter bushings included
