Note: To ensure proper axle alignment and suspension performance, leaf springs should always be replaced in pairs.


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


Slipper leaf springs attach to hangers that are welded onto your trailer. The eye of this spring will attach to the front hanger with a suspension bolt. The hooked slipper end of the spring will slide into the rear hanger. If you have a tandem- or triple-axle trailer, the slipper end will slide into the equalizer that connects multiple springs. The shape of the slipper end of a leaf spring may vary slightly due to differences among trailer manufacturers. Because of this, it's important to check your leaf spring's slipper end before purchasing a replacement spring.


To mount this spring, you will need hangers, a suspension bolt, and possibly a spring keeper bolt, depending on the design of the rear hanger. If you are simply replacing a spring, you may still have hangers welded onto your trailer, but it would be wise to replace the bolts as they can experience wear. It is also 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 trailer could be affected.


If you are fabricating a trailer, 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.

The spring capacity is 2,000 pounds and axle capacity is 4,000 pounds. A few length measurements that we want to go over with you real quick. Measuring from the center of the eye to the end of the spring, that's going to give us a measurement of around 26 5/8". Then, from the center of the eye to the top of the curve right here or the bend, that's going to give us a measurement of about 24 5/8".

  • Upgrading Tire Size and Suspension on a Homemade Hovercraft Trailer
  • The wheels that are currently on your tires are 3-3/4 inches wide, but the width of the actual tire (section width) will be greater. The section width of your 4.80/4.00-8 tires is 4.6 inches. Moving up to a 6 inch wide, 10 inch diameter wheel like the Kenda 205/65-10 Tire and Wheel Combo 4 on 4 Bolt Pattern, # AM3H460, will have a section width of 8.07 inches. This will bring the tire approximately 1-3/4 inches closer to the trailer frame leaving a 1-3/4 inch gap. This will be plenty...
