1999–2007 Ford F-350 – 1 Inch Rear Leaf Spring Lowering Shackle Kit

If you're looking to fine-tune the stance of your 1999–2007 Ford F-350 Super Duty truck without compromising ride quality or load-carrying capacity, the 1-Inch Rear Leaf Spring Lowering Shackle Kit is the perfect solution. This kit is precision-engineered to drop the rear of your truck by a modest but impactful 1 inch, helping to eliminate factory rake, achieve a leveled stance, and improve overall aesthetics.

Ideal for both show trucks and workhorses, this rear lowering shackle kit is crafted from high-strength steel, coated for corrosion resistance, and includes urethane bushings for quiet, long-lasting operation. Whether you're building a street cruiser, a tow-ready hauler, or a SEMA-ready showcase vehicle, this kit delivers the performance and dependability Ford truck owners demand.

Key Features and Benefits

Achieve a Leveled Stance

From the factory, Ford’s heavy-duty trucks often sit higher in the rear to accommodate hauling heavy loads. However, many truck owners prefer a level or slightly raked appearance. This 1-inch rear drop shackle gives you just enough rear-end drop to level out the stance, without affecting suspension geometry or over compressing the leaf springs.

* Retain Factory Ride Quality

This kit is engineered to maintain factory ride comfort and handling, unlike more aggressive drop setups that require re-arching or flipping leaf springs. Since only the shackle is being modified, there’s no need for shock extenders or custom bump stops with a 1-inch drop.

* Perfect Starting Point for a Custom Build

Thinking about a complete lowering kit down the road? This shackle kit can be used as a first-stage modification before adding hangers, drop leaf springs, or other suspension components. It integrates seamlessly into a staged lowering plan.

* Bolt-On Installation

No welding or fabrication needed! This direct bolt-on kit uses your existing frame mounts and leaf spring eyes, making it an ideal DIY project. Most installations can be completed in under 2 hours using basic tools and a floor jack.

* Premium Construction

This isn’t a budget kit—it’s built to last. Features include:

• Laser-cut heavy-gauge steel construction

• Durable black powder coat finish

• High-performance polyurethane bushings for quiet, long-life operation

• Zinc-plated hardware included

• Designed to meet or exceed OEM specs

Compatibility

This shackle kit is specifically designed to fit:

* Will not fit F-250 or F-150 trucks due to frame and leaf spring dimension differences. For those applications, check out our full range of F-Series Lowering Components.

Why Lower Your Ford F-350 with Shackles?

Even a subtle 1-inch drop can make a big difference in both style and drivability. Whether you’re trying to match the rear height to a front drop or simply reduce the "nose-down" look, this kit delivers a cost-effective, minimally invasive method of achieving your ideal stance.

Plus, because the Ford F-350 features rear leaf springs, lowering shackles are a safe and proven solution. Unlike cutting coils or removing leafs (which compromise load rating), shackles preserve strength and geometry.

• Show Trucks – Improve your profile without needing a full drop kit

• Towing Vehicles – Maintain towing capacity and leaf spring arch
