Belltech SHACKLE KIT FITS 2.5inch LEAF SPRG - 6400 - BEL6400

The Belltech Shackle Kit (Part #6400) is a simple, economical solution for lowering the rear of your leaf-spring-equipped truck to achieve that clean, leveled stance. Designed to work with 2.5-inch leaf springs, this rear lowering shackle kit from Belltech delivers a no-nonsense drop in the 1–3 inch range, helping eliminate the factory rake and giving your truck a more aggressive, road-ready profile without a full suspension overhaul.

Key Features & Benefits

• Heavy-Gauge Die-Stamped P&O Steel Construction: These shackles are built from pickled-and-oiled (P&O) steel that has been die-stamped for consistent, repeatable dimensions — meaning you get a part that fits correctly every time and holds up under real-world truck use.
• Powder Coat Finish: The powder coat exterior protects against corrosion, road salt, and moisture, keeping the shackles looking clean long after installation.
• OEM-Quality Vulcanized Rubber Bushings: Belltech specs these shackles with vulcanized rubber bushings engineered to OEM standards, ensuring a smooth, rattle-free ride and a fitment that matches factory tolerances — no sloppy, worn-out feel right out of the box.
• 1, 2, or 3 Inches of Rear Drop: This kit gives you meaningful, adjustable lowering in the rear to correct the factory nose-up rake common on many trucks, improving aesthetics and handling balance.
• Economical Alternative to a Full Suspension Kit: If you want a leveled look without investing in a complete lowering kit, Belltech's shackle kit is one of the most cost-effective entry points into truck suspension modification.
• Fits 2.5-Inch Leaf Springs: Specifically engineered for trucks running 2.5-inch leaf spring width, ensuring proper seating and load transfer without improvised adapters or shimming.

Fitment

The Belltech #6400 Shackle Kit is designed for leaf-spring-equipped trucks with 2.5-inch leaf springs. Because Belltech produces multiple shackle kits for different leaf spring widths and drop amounts, it is critical to confirm your truck's leaf spring width before ordering. If your truck uses a different leaf spring width, or if you need a different drop profile, Belltech offers alternative part numbers (such as the 6401 for a 2 or 3 inch drop in a different application). Always cross-reference your specific year, make, model, and trim level — and verify your factory leaf spring width — before purchasing. If you are unsure which shackle kit fits your truck, contact our fitment team before ordering.

Frequently Asked Questions

What leaf spring width does the Belltech 6400 shackle kit fit?

The Belltech #6400 is specifically designed to fit 2.5-inch leaf springs. If your truck runs a different leaf spring width, you will need a different Belltech shackle kit. Confirm your factory leaf spring width before ordering.

How much will this kit lower the rear of my truck?

According to Belltech, this shackle kit provides 1, 2, or 3 inches of rear drop depending on the configuration, helping to level out the factory rear-high rake common on many pickup trucks.

Are the bushings included, or do I need to source them separately?

Yes — the Belltech 6400 kit comes with OEM-quality vulcanized rubber bushings already included, so you should have everything needed for a straightforward installation.

Is this a difficult installation for a home mechanic?

Belltech markets this as a simple, economical rear lowering solution compared to more involved suspension kits. That said, any suspension work involving leaf springs and shackles requires proper jack stands, torquing to spec, and an alignment check afterward. If you are not comfortable with suspension work, professional installation is recommended.
