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.

6 spring showed up loose in a cardboard tray. No cover, no tape, no label. UPS driver didn't even know if everything was there. It was by some luck.

See what our Experts say about this Universal Group Trailer Leaf Springs
- Troubleshooting End of Slipper Spring Popping Out on 2023 Outlaw Gooseneck Flatbed TrailerThe 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...

- Replacement 28-1/2" Slipper Spring for 4,100 Pound Karavan Boat Trailer With 6,000 Pound AxlesLeaf springs typically flatten over time so that 28-1/2" measurement was likely a bit shorter originally unless you already accounted for that. Although they probably didn't shorten a full 1-7/8" you will be able to use the 4-Leaf Slipper Spring w/ Hook End # SP-231275 as a replacement. This slipper spring measures 26-5/8" long, 1-3/4" wide, and has a 5,000 lb capacity. I realize it does not match your axle capacity, but you're limited by the trailer capacity of 4,100 lbs so this is more...
view full answer... - How to Choose Correct Replacement Slipper Spring for 1981 Daily Boat TrailerBy slider leaf spring, I'm assuming you mean a slipper spring. To recommend a suitable replacement, I'll need to know the capacity of the axle (this can be determined from the wheel bolt pattern, the diameter of the axle or from the reference numbers from the inner and outer wheel bearings. Getting an accurate measurement of the spring length is important as well, because the springs can flatten out over time. Is the measurement you took from the center of the eye to the very end of...

- Can I Remove a Leaf From the Bottom of a 4-Leaf Slipper SpringEh, yeah, don't do that. The weight capacity of the leaf spring will definitely be affected but it will be reduced to an unknown capacity so if you were to remove a leaf from say part # SP-231275 that has a 5,000 lb capacity then you would essentially be playing with fire when it comes to that leaf spring working properly. You need to keep the leaf springs completely intact and make sure they match whatever other leaf springs are on your trailer, plus whatever you do to one side of an...
view full answer... - How to Pick the Right Replacement Leaf Spring for my TrailerThe actual weight of the load isn't important when determining what springs you'll need- you will actually need to go by the axle capacity paired with the type of spring and its's length. For your 5000-lb axle, your single spring capacity will need to be at least 2500-lbs- but you'll also need to know whether or not they are double eyed or slipper springs, and how long they are (roughly, since worn springs will be slightly longer when measured eye to eye). As far as springs we have available...
view full answer... - Do you have a spring that is 24 center to center and a reverse curve and closed eye?We do not have a spring that fits that specifically. In our 3 leaf springs we have two that are closed eye on one end and reverse curve on the other. The # SP-039275 measures 30" center to end of spring and the # SP-178275 measures 22-3/4" center to center. If you are able to go up to the 4 leaf spring we have # SP-231275 which measures 24-5/8" center to center. If you want to go the 4 spring route the added capacity of the 4 leaf would bring you up to 2,500 lbs per spring which will...
view full answer... - Recommended Slipper Spring Suspension for 10,000 Pound TrailerFor Slipper Springs to install on your trailer that will have a maximum load of around 10,000 pounds, I recommend either the 5-Leaf Slipper Spring w/ Hook End for 6,000 pound Axles # e67SR or the 4-Leaf Slipper Spring for 5,000 Pound Axles # SP-231275, depending on the actual axle capacity for your trailer. Then for a hanger kit, which will work for either of the Slipper Springs mentioned above, I recommend the Tandem-Axle Trailer Hanger Kit for 2 Inch Slipper Springs # AP216-H202. This...

- Hangers to Use with Slipper Springs SP-231275Since the springs part # SP-231275 are 2 inches wide the hanger kit part # HAP-105-00 that you referenced would work great.
view full answer... - Slipper Spring for 5,000 lb Trailer AxleThe amount of leaves on a slipper spring won't really be an issue. As long as the length and capacity is correct you'd be good and not need to worry about how many leaves you have. For a 5,000 lb axle slipper spring that measures 26-5/8 inches you'd want the part # SP-231275.
view full answer... - How to Determine Axle Spacing on a 5,000 lb Tandem Axle TrailerThe exact axle spacing will depend on the hanger kit and leaf springs you are using. For example, for a trailer with two 5,000 lb axles, we recommend using hanger kit, # APT6SE, and 4-Leaf Slipper Springs for 5,000 lb Axles, # SP-231275. The spring length and equalizer length will play a big role in determining axle spacing. The hanger kit comes with a 12 inch long equalizer and the 5,000 lb slipper springs are 24-5/8 inches long. For this combination, the distance between the front hanger...

- Leaf Spring Replacements Compatible With 10K Trailer With Dual AxlesFor your replacement leaf spring on your 10K trailer with dual axles, you will want a spring rated at 2,500 lbs capacity or more so the 2 springs that attach to your axle will not limit your trailer capacity. For instance we have the 4-Leaf Double-Eye Spring for 5,000-lb Trailer Axles - 25-1/4" Long # e44SR or the 4-Leaf Slipper Spring w/ Hook End for 5,000-lb Trailer Axles - 26-5/8" Long # SP-231275 each rated for 2,500 lbs. The measurements of your current springs will also be an...
view full answer... - Recommended Hangers for Slipper Spring SuspensionThe 4-Leaf Slipper Spring w/ Open Eye End for 4,300-lb Trailer Axles - 26-1/4" Long # e33SR is a 1-3/4 inch wide spring, so I recommend using the Single-Axle Trailer Hanger Kit for 1-3/4" Slipper Springs # APS3SE for these springs if you have a single axle trailer. If you have a tandem axle trailer, you will want to move to 2 inch wide springs like # SP-231275 and use a kit like # APT6SE.
