How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

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.
