What Is a Trailer Shackle?
Shackles are a vital component of a trailer’s suspension system. These components help to provide stability and support for a variety of different trailer types.
They are available in a variety of shapes and sizes, and they can come with a range of different attachment methods. In this article, we’re going to take a look at some of the most common types of shackles used on trailers.
Leaf Spring Shackles
Leaf springs are a vital part of any truck or SUV’s suspension system, as they help to center the axle and support the weight of the vehicle. However, they cannot do their job without a shackle to allow the leaf spring length to change accordingly during suspension travel.
Shackles are located at the rear end of each leaf spring, and they help to link the spring to the frame of the vehicle. This enables the leaf spring to flex and move when the vehicle is being bumped or tossed around on rough roads, making it easier for your vehicle to ride smoother.
While shackles are not the most visible parts of your suspension system, they are important for keeping your leaf springs in place and ensuring they work properly. They can cause a number of problems if they become worn out or damaged, so it’s best to replace them when they’re necessary.
The eye of a shackle is where it meets the main leaf of the spring, and this angle will determine the overall droop travel of a spring. The longer a shackle, the more likely it is to droop inward or outward as the suspension moves.
When a shackle reaches this limit, it stops drooping and begins to compress, thereby reducing the maximum distance the spring can travel under the suspension. This is why shackles use rubber or polyurethane bushings to allow the spring to twist in response to the bolts that hold it in place.
If you’re in the market for new shackles, General Spring offers a variety of options to choose from. We also have kits to help you upgrade your old, worn out shackles to more durable ones.
While shackles aren’t the most visible parts of your suspension system, you can tell when they are worn out or damaged. They can cause a number of problems, including a harsh ride, leaning to one side and broken springs. Additionally, they can cause odd noises as the springs flex and move, which can be an indication that something is wrong.

Non-greaseable bolts are a cheaper option, but they can also break down and become brittle more quickly. This is especially true if you drive on dirt roads or gravel, which can erode the threads of your shackle bolts over time.
