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.

helpful and great at their job. I can tell they all enjoy helping us out here fix our trailers and get them back on the road quickly and safely. Now I have to get back to work to get my leaf springs back on !

  • Can I Switch From 5-Leaf Slipper Springs to 7-Leaf Springs?
    You can switch from a 5-Leaf # e74SR to a 7-Leaf # e37SR as long as you are replacing all your leaf springs. Do note the 7-leaf springs are going to be roughly 3/4" taller so you may also need taller U-Bolts like the # MR66ZR which are 7-3/4" tall.

  • Replacement Springs for Sanibel 3500 with Dual 8000-lb Dexter Axles
    Since you have 8000-lb axles, we know that they will use slipper springs and I can narrow your options down to 2 different sized replacement springs for your Sanibel 3500 5th Wheel. In order to choose the right one you'll need to determine the length of the spring. You can measure the length of the spring from the center of the eye on one side to the end of the spring. If you have 29-1/2" long springs you will need # e46SR . If you have 26-5/8" long springs you will use # e37SR. Keep in...

  • Replacement Spring Hangers And Suspension Components For 8,000 lb Axles
    I can certainly point you in the right direction on a few of the parts you will need. Unfortunately we do not carry a 20-3/4" long equalizer, so we do not have any kits that would accommodate that hanger size and axle spacing. We do have a few hanger kits for 2" wide slipper springs like the # H202. This comes with 4-1/4" tall front hangers, 3-1/2" tall center hangers and 5-1/4" tall rear hangers. We do not have any hangers that are 7" tall. We do have the Wet equalizer bolt # TRFA71063,...

  • Will 7-Leaf Slipper Spring Work If It's 1/4" Shorter Than Current Leaf Spring
    It isn't uncommon for leaf springs to expand a little over time as they start to wear down and flatten out. Since your leaf spring measures 26-7/8" that's only 1/4" more than the 7-Leaf Slipper Spring w/ Hook End for 8,000-lb Trailer Axles # e37SR which is perfectly normal so you'll be good to go in those regards. As a rule, whatever happens to one side of the axle needs to happen to the other side of the axle to keep everything operating and wearing smoothly so you definitely want to...

  • U-Bolts For 3-1/2 Axle to Mount 8-Leaf Trailer Springs
    The Replacement U-Bolt w/Nuts # 11-65 will fit the 7-Leaf Slipper Spring # e37SR. This u-bolt has a 3-1/2" opening inside the bolts. It is 8" long from the inside of the u-bolt to the end of the threads. The U-Bolt Plate # 117581 will work with both these springs and u-bolts to secure the parts together.

  • How to Determine Correct Replacement Slipper Springs for Triple Axle Trailer With 8,000 lb Axles
    I can help you determine exactly what you need to replace the suspension in your triple axle trailer, although we don't have any type of database which has each part for each year, make and model of trailer that would tell us exactly what you have on your trailer, which means you'll need to do a bit of pretty simple measuring. Since you have a triple axle trailer, with three 8,000 lb axles you will need slipper springs for that axle capacity, for which we have two of that capacity. To...

  • Are Double Eye Leaf Springs Rated For 8,000 lb Axles
    Thank you for that detailed information and what I can tell you is that when choosing leaf springs, the actual number of leafs isn't the most important thing, the weight rating and center-eye to center-eye measurement is what you need to know. I have added a cut out from the help article on double eye trailer suspension which I highly recommend reading. We do not carry double eye springs rated for 8,000 lb axles and there is no way for us to know the rating of your currently installed...

  • Leaf Springs for 8K-Rated Axle
    We do offer both double-eye and slipper-type leaf springs for many axle weight ratings. You can see all of these leaf springs on the page I linked for you. In the 8K axle capacity we offer two slipper-type springs. Part # e39SR is a 6-leaf slipper spring that is 29-1/2-inches long. Part # e37SR is a 7-leaf spring that measures 26-5/8-inches. Both are 2-inches wide. Please note that leaf springs tend to stretch when they are worn so the length of the old spring you remove may measure...

  • Recommended Triple or Quad Axle Suspension for Trailer Build
    Since you are building a trailer I first want to state that using quad axles isn't ideal. It will cause tire scrub as there becomes too broad an axle base for the trailer to track as nicely. That is why most trailers will use tandem or triple axles as needed for load capacity. If you just want to add the 4th axle for overbuild reasons it will bite you as you will need to replace tires more often. Most of the professional semi flat bed trailers that have the quad axles are for transporting...

    I would be more than happy to help you get everything together that you need for the suspension on your gooseneck trailer for your tiny house! It sounds like you're needing the Dexter Trailer Axle w/ Electric Brakes - E-Z Lube - 8 on 6-1/2 Bolt Pattern - 95" - 7,000 lbs # 8327834-EB which has a hub face measurement of 95" and a spring center measurement of 80".

  • What Would Cause the Front Eye on my Slipper Springs to Unwind or Loose its Shape
    The load or hitch height would not affect the front spring eye. For it to come unwound or loose its rounded shape there has to be some kind of rearward force pulling it out of round. This would shift the front axle effecting the equalizers and the tire spacing. The best bet here is to replace that front set of slipper spring and inspect it regularly to determine when the damage has occurred. We carry a good selection of slipper springs like the 7-Leaf Slipper Spring w/ Hook End for 8,000-lb...
