BST BSSP Rear Leaf Spring Shackle Kit for Ford Super Duty & Excursion 1999-2007 — Pair with Bushings & Hardware

BST BSSP Rear Leaf Spring Shackle Kit 722-018 is a complete pair replacement for the left and right rear leaf spring shackles designed to match original equipment fit and restore proper suspension alignment on compatible 1999–2007 Ford Super Duty and Excursion trucks.

This kit supplies the two rear shackles, replacement bushings and all mounting hardware you need to replace worn or damaged shackle assemblies. Manufactured from durable steel with a corrosion-resistant powder coat finish, the components are engineered to meet the form and function of the OE parts (replacing dealer part numbers E5TZ-5K316-A / E5TZ5K316A). The kit fits both driver (LH) and passenger (RH) sides and is intended strictly as a direct shackle replacement—not a complete spring assembly.

Which vehicles and years will this shackle kit fit?

This BST BSSP shackle kit is built to fit a range of late‑1990s through mid‑2000s Ford heavy trucks and the Excursion. Always verify fitment against your vehicle’s exact year and trim before purchasing.

• Compatible models include Ford Excursion (2000–2005) and F‑250/F‑350/F‑450/F‑550 Super Duty ranges spanning 1999–2007 depending on model.
• Also referenced to part numbers E5TZ‑5K316‑A, 1C3Z5776BA and internal code 722‑018 for cross‑checking.
• Fits left (driver) and right (passenger) rear leaf spring shackles only.

What comes in the kit and what will I need to install it?

The kit contains both shackles pre‑assembled with bushings plus extra spring bushings and all required fasteners, so you can swap the shackles without sourcing additional parts. Basic hand tools and a safe way to support the vehicle are required for installation.

• Included: 2 shackles with bushings, 2 spare spring bushings, 4 mounting bolts and 4 locking nuts.
• Materials: heavy‑gauge steel construction with powder coat for rust resistance.
• Installation needs: jack and stands, socket set, torque wrench, and routine safety precautions.

How does replacing the shackle help vehicle performance?

Worn shackles and bushings allow excessive movement at the spring eye, which causes uneven ride, noise, and alignment shifts. Replacing only the shackles returns the intended pivot point and reduces play without replacing the full spring pack.

• Restores correct rear suspension travel and pivot alignment.
• Reduces clunking, squeaks and irregular axle movement when driving.
• Extends life of the leaf springs by maintaining proper loading geometry.

Are these shackles the same as original equipment parts?

Yes—this kit is designed as a direct replacement matching the design and dimensions of the original shackles for the specified Ford models. It replaces the OE dealer part numbers and is intended to perform like the factory component.

• Direct replacement fit and mounting points mirror OE specifications.
• Cross‑references: E5TZ‑5K316‑A, E5TZ5K316A and 1C3Z5776BA to confirm compatibility.
• Manufactured under quality control standards to ensure consistent performance.

Who this is for: This shackle kit is aimed at owners and mechanics of late‑1990s to mid‑2000s Ford Super Duty trucks and Excursions who need a cost‑effective suspension repair. Choose this set if your vehicle shows rear suspension play, noisy spring mounts, or you are replacing worn bushings but do not require a full leaf spring replacement. Always confirm vehicle fitment with your VIN or the garage fitment tool prior to ordering.
