Description

These heavy-duty rear lowering shackles are built for 1999–2026 Ford F-250, F-350, and F-450 trucks, including both 2WD and 4WD models. Unlike most lowering shackles on the market, these are manufactured from 1/4" laser-cut steel and DOM tubing for serious strength and long-term durability.

Each shackle uses a polyurethane bushing with a grease zerk and a heavy-duty zinc-plated inner sleeve. The longer shackle design can also allow the rear leaf spring to flex more freely, giving the truck a slightly softer ride feel.

Key Features

  • Fits rear of 1999–2026 Ford F-250, F-350, and F-450 trucks
  • Compatible with 2WD and 4WD models
  • Heavy-duty 1/4" laser-cut steel construction
  • DOM tubing for added strength
  • Polyurethane bushings with grease zerks
  • Zinc-plated inner sleeves
  • Three adjustable leaf spring mounting locations
  • Bolts in using OEM hardware
  • Payload capacity is not affected
  • Powder coated finish included standard
  • Manufactured in-house in the USA

Adjustable Rear Drop Amounts

These shackles feature three mounting holes, allowing the user to fine-tune rear ride height when used with OEM leaf springs.

Hole Position Approximate Rear Drop
Position 1 1/4"
Position 2 7/8"
Position 3 1.25"

Note: Aftermarket leaf springs may respond differently than OEM leaf springs.

Installation Notes

  • Installs at the rear side of the leaf spring only
  • May change leaf spring, axle, and pinion angle
  • Trucks with top-mounted overload springs may engage the overload sooner or differently
  • Pinion angle changes may cause vibration in some applications
  • Pinion shims may be required and are sold separately
  • Trucks with overload air bags may require mount modification or replacement
Important: These shackles lower only the rear side of the leaf spring. Always verify driveline angle, overload spring clearance, and air bag mount compatibility after installation.
