BST BSSP Rear Leaf Spring Shackle Kit PAIR SET for 1999–2007 Ford Super Duty & Excursion — Pre‑fitted Bushings, Powder‑Coated

BST BSSP Rear Leaf Spring Shackle Kit 722-018 is a complete pair replacement set (left and right) that restores proper rear leaf spring connection for compatible 1999–2007 Ford Super Duty, Excursion and E‑series models.

This shackle kit comes complete with two shackles pre-fitted with bushings, two replacement spring bushings, four mounting bolts and four locking nuts so you can replace worn or damaged rear shackle hardware without sourcing individual parts. Each component is engineered to match the original equipment fitment and dimensions, using powder‑coated steel for corrosion resistance and long service life. Confirm fit with your vehicle year, model and trim before purchase.

What vehicles does this BST BSSP shackle kit fit?

The kit is designed for a range of Ford trucks and vans from the late 1990s through the mid‑2000s. Fitment covers both LH (driver) and RH (passenger) rear leaf spring locations on specified models and model years.

• 1999–2007 F-250 and F-350 Super Duty applications
• 1999–2004 F-450 and 1999–2002 F-550 Super Duty where applicable
• 2000–2005 Ford Excursion and 2003 E‑550 (check vehicle specifics)

How does this kit replace the original shackle hardware?

Each kit component is manufactured to match OE design and dimensions so installation is straightforward and aligns with factory mounting points. The kit replaces only the rear leaf spring shackle, not the entire spring assembly.

• Direct replacement for dealer part E5TZ-5K316-A / E5TZ5K316A
• Includes shackles with preinstalled bushings for easier fit-up
• All fasteners (bolts and locking nuts) supplied to complete both sides

What materials and finish are used for durability?

The shackles are formed from heavy‑gauge steel and receive a protective powder coat to resist rust and extend service life in road and weather exposure. Bushings are selected to match the original mounting geometry and provide proper articulation for the leaf spring eye.

• Durable steel construction for load stability
• Powder‑coated finish for corrosion resistance
• Replacement bushings to restore proper movement and reduce wear

What comes in the kit and what should I prepare for installation?

The kit contains all the essential parts to change both rear shackles; you’ll still need standard hand tools and proper jacking/supports to safely remove and reinstall the leaf spring hardware. Ensure the vehicle is supported securely and follow torque specs for mounting fasteners.

• Included parts: 2 shackles with bushings, 2 spring bushings, 4 mounting bolts, 4 locking nuts
• Recommended: jack stands, torque wrench, penetrating oil for old fasteners
• Verify correct part for your specific model and year before starting work

Who is this for: This BST BSSP Rear Leaf Spring Shackle Kit is intended for owners, mechanics and restoration shops servicing 1999–2007 Ford Super Duty trucks, Excursions and compatible E‑series vans who need a direct OE‑style replacement for worn or damaged rear spring shackles. It’s ideal when the original shackles show wear, bushings are degraded, or when replacing hardware during spring or suspension repairs.
