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 flat 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.

- Quantity Included On The 3-Leaf Slipper Spring with Radius End # e99SRThe 3-Leaf Slipper Spring w/ Radius End # e99SR comes with one single spring. You will have to purchase two to complete the axle. This spring has a measurement of 24-5/8 inches from center of spring eye to center of spring eye. The spring is for a 1,500 pound axle capacity. It has a sturdy steel construction and the nylon bushings are included. I attached a review video link below.
view full answer... - How to Verify The 3-Leaf Slipper Spring # e99SR Will Replace the Spring on the Trailer. To verify the 3-Leaf Slipper Spring # e99SR will fit your trailer you will need to take the weight off your current leaf spring so you can compare it with the measurements. Please see the image below to know where to measure and know the lengths A, B and F could be different depending on how much the spring sags. This leaf spring is 1-3/4" wide. A: 11" B: 22-3/4" C: 24-5/8" D: 12" E: 14-1/2" F: 4" If you find your measurements are different please let me know what you find so I can...

- Should Leaf Springs on Trailer Sit Totally LevelIdeally the leaf springs sit as level as possible. If they are going to angle at all you would want the front maybe a little higher than the rear but perfectly level is the most ideal. I would recommend using the mounting holes that allow it to sit totally level.
view full answer... - Does Trailer Need to be Jacked Up to Measure Leaf Spring for ReplacementJacking up the trailer frame to get the load off of the leaf spring is needed to get accurate dimension of spring for replacement. It would seem unlikely that your spring would be 24.5 inches if when there's a load it's 26 inch but you never really know. You will also need to know the axle capacity of your trailer as well.
view full answer... - Can I Replace Leaf Springs With Lower Rating For Better Ride QualityYes, you can swap from the 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # e99SR to the 2-Leaf Slipper Spring w/ Radius End for 1,000-lb Trailer Axles - 24-5/8" Long # e36SR to help reduce how much shock is being transferred to your trailer frame. My only caution going this route is to make sure you don't overload the leaf springs since you're reducing their weight rating. Attached is a review video for you to check out.
view full answer... - What Info is Needed to Pick Out Replacement Trailer Leaf SpringThe amount of leaves isn't actually that important when picking out replacement leaf springs. What you really need is the axle capacity and the length of the old springs. With that info you can know what you would need. For example our most popular option is the part # e54SR which is for a 3,500 lb axle and is 25-1/8 inches long.
view full answer... - Does 3-Leaf Slipper Spring w/ Radius End Require a Bushing for Rear of SpringFor the 3-Leaf Slipper Spring w/ Radius End # e99SR you only need the bushing on the one end, the other end will either sit over a bolt or will fit into a hanger like part # 115706S. If you have a double-eye spring on your trailer then you'll need something like the 25-1/8" Long 3-Leaf Double-Eye Spring # e66SR instead. Attached are some videos for you to check out as well.
view full answer... - How Much Distance Should I Have Between The Tire And The Trailer Frame?I can certainly point you in the right direction. I will start by saying that our "rule of thumb" is that we want at least 1" of clearance between the tire and the trailer frame. With the hub face currently at 48", you will want to go with an axle that is at least 50" hub face, if not a bit longer. 54" would be acceptable, but we would not want to go longer than that. Unfortunately, we do not offer any axles that will be close to this size. Our shortest round tube axle is 60" hub face....

- Is There Difference in Quality Between 1,500 lb 3-Leaf Slipper Spring e99SR & SP-178275There really is not any type of quality difference between the two slipper springs: - 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # e99SR & # SP-178275 They both have the same measurements, steel construction, and nylon bushing in the spring eye. I'd honestly go with the least expensive option to save yourself some money. Also, I do recommend new bolts when mounting springs, the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079.
