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.

  • Replacement 25" Slipper Spring Needed for 3,500 lb Axle
    For your application I recommend using the 4-Leaf Slipper Spring w/ Hook End for 4,000-lb Trailer Axles # SP-230275. This measures 26-5/8" to the end of the spring but if you check out the attached photo you'll see that it will fit great with your 25" measurement. This is rated for a 2,000 lb axle and has a 2" width which are the only other things you need to check when choosing a replacement spring. Attached is a review video for you to reference. Please note that at this time (February...

  • Determine Axle Rating by Measuring to Get Correct 2 Inch Wide Leaf Slipper Springs
    In general, you can measure the diameter of an axle tube to get the rating, though it is more of a guideline and the only way to know for sure is by some identifying marker on the axle and contacting the manufacturer. However, since that isn't a possibility for you, then measuring the tube is the best option, just know that it isn't a 100 percent guarantee. Here are the general ratings: - 1,000 lb – 2,000 lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500 lb Axles: 2-3/8 inch diameter -...

  • Hanger Spacings for Trailer Suspension Hanger Kit AP216-H238 with 26-5/8 inch Slipper Spring
    When you use the Tandem-Axle Trailer Hanger Kit # AP216-H238 with the 4 Leaf Slipper springs part # SP-230275 the distance between the front hanger and the center hanger will be 30-1/2 inches, the distance from the center hanger to the rear hanger will also be 30-1/2 inches. This will put the axle centers at 36 inches apart.

  • Troubleshooting End of Slipper Spring Popping Out on 2023 Outlaw Gooseneck Flatbed Trailer
    The picture with the torn up bushing looks like the eye of your slipper spring. Is that correct? If so, it is coming undone and probably the reason you're having this problem. It should be enclosed and not look similar to the hook on the end of the slipper spring. Replacing your leaf springs will likely solve the issue. This is a new 2023 trailer so you also might want to check to see if the dealer is willing to cover any repairs. That isn't exactly normal unless you're grossly overloading...

  • 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...
