Leaf springs are an integral part of your Truck suspension system. The leaf springs provide the attachment points for your truck’s axle, suspending it from the frame of your Truck. Each spring flexes to absorb road shock as you travel, allowing the axle to move somewhat independently of the rest of your truck. This helps to reduce wear and tear on the truck and also ensures a smooth ride.

Double-eye leaf springs attach to hangers that are welded onto your truck. One end of this spring will attach directly to the hanger with a suspension bolt. The other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem- or triple-axle truck, the shackle straps will be attached to the equalizer that connects multiple springs.

To mount this spring, you will need hangers, shackle straps, and suspension bolts. If you are simply replacing a spring, you may still have hangers welded onto your truck. You should, however, replace your shackle straps because they are usually the first component to wear out. You may choose to replace old suspension bolts as well. It is recommended that you replace the other leaf spring in your setup at the same time. Because springs can sag and elongate as they wear, this new spring may not exactly match the old one, and the alignment of your truck could be affected.

If you are fabricating a truck, you will need to purchase a hanger kit for installation. To determine the type of hanger kit that you need, you must know the specific type of leaf spring that you have, as well as your axle capacity. Depending on the hanger kits used with them, springs can be configured to work for single-, tandem- or triple-axle applications. Hangers and other suspension components can also be purchased separately if there isn’t a complete kit that works for your setup.
