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.


Double-eye leaf springs attach to hangers that are welded onto your trailer. One end of this spring will attach directly to the hanger with a suspension bolt. The other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem- or triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs.


To mount this spring, you will need hangers, shackle straps, and suspension bolts. If you are simply replacing a spring, you may still have hangers welded onto your trailer. You should, however, replace your shackle straps because they are usually the first component to wear out. You may choose to replace old suspension bolts as well. It is 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.

Having the exact replacement leaf springs for our trailer was a game changer. Excellent quality, doing the job just fine.

Super fast shipping. Perfect replacement, bolted right up. We replaced the 3500 lb. springs with the 4000 lb. springs, works great, raised it up slightly and it's less bouncy.




by:

I ordered the Dexter Heavy Duty Suspension Upgrade Kit and a set of leaf springs for my travel trailer, and they arrived in 1 box in 5 days (counting the weekend days) from Missouri to Maine. Very impressive especially for free shipping (over the $xx minimum). They were an exact match for the originals and fit perfectly.




by:

I ordered the springs a couple days after I ordered the Morryde CRE 3000. The Springs got here a couple days before the Morryde. Very fast shipping.
I have yet to pull the trailer, but I feel like this upgrade will save me down the road..
Thanks




by:

Good springs, delivered on time , exact fit, will use e trailer again in the future




by:

Perfect fit. My old springs were rusted at the eye and broke, which is why I needed to replace. Due to trailer overload. These springs are performing well in the last year. Great quality!




by:

Works well the my trailer .




by:

So far so good... nice to have a few extra hundred pounds capacity compared to 3500 springs.

I called customer service and worked with William B. He was patient and listened while i described problem and sent pictures to him for review and advice. He took time to search forums and find out specifications of the boat trailer which happened to be quite old. Helped solve a challenging problem and called me back quickly when had some questions about my order. he also sent me an email about the status of the order and let me know when it shipped. I was very impressed with the customer service. I ordered several size options and etrailer was great to work with. The trailer was for a boat MasterCraft Prostar 205 from '90s and wasn't able to measure the springs correctly because it was 3 hours drive away. Thanks for great service.




by:

Good quality and value for the price. 1 year later, showing minor rust on the leaf ends and at the bands. A coat of paint before installation might be a good idea if you're worried.

I would use a thin coat of lithium grease to prevent rust on a product like this. Here are more tips attached in this help article:

by:

The springs fit great. The bushings for the MoRyde fit perfectly inside. Great Fit for my 2600RB




by:

an inexpensive way to beef up your suspension. best to get at least 2 of these before you really need them, easily stored somewhere either in tow vehicle or trailer storage. had one break on my trailer and it cost me $200 to have one fabricated and installed which is more than 6 times the price of one here.




by:

Great replacement for worn parts.




by:

Just what I expected awsome product




by:

They have been great for several hundred miles so far.

Had a broken spring on my 16 year old trailer. Found correct parts to replace all 4 springs and hardware in one place. Everything fit and worked great at reasonable prices.




by:

Exactly as advertised worked great!

Purchased a Leaf Spring - my boat trailer just like new!




by:

I bought 4 of these to replace the deformed springs on our 2013 travel trailer that were damaged in a frightening traffic incident in June. I opted for these 2,000 lb. springs versus the 1,750 lb. OEM replacement units since the fit was equivalent and I wanted to ensure sufficient sustained clearance inside the wheel wells. I had no difficulty removing the nylon bushings and installing the bronze ones from the upgraded Dexter suspension kit which I also purchased, and the springs fit perfectly. I'd have given them 5 stars, but they weren't individually boxed so they each suffered some scuffing during shipment which has already resulted in a few premature rust spots appearing.




by:

appear to be quality springs - promptly shipped. Went on without a hitch as part of a complete tandem axle trailer overhaul. I had ordered these at the same time that I placed an inquiry about a previous order to another company regarding a brake kit - received these at my door before receiving an email response from the other company!! Later learning, after making a phone call to the other company, that my brake order was not in stock and would be 2-3 weeks for shipping. Decided to cancel other order and buy the brake kit from etrailer - received it within 4 days. Great customer service - will go straight to etrailer for all my replacement parts in the future. Lesson learned!




by:

Fast and the perfect fit for my bass tracker boat trailer.




by:

Bolted right on!




by:

I'm So glad I found etrailer.com ! When the leaf spring broke on my lawn service trailer , I didn't know where to turn. etrailer.com Was very helpful and the Price was Great! I ordered them and They arrived Monday! I was very Impressed, what with it being the Holidays and all. My Husband was able to change them out and now greenie and I are back to work. Thank you for your Great service!

  • Does the Shackle Angle have to be the Same Angle on both Sides of my Trailer Suspension
    Most likely you are fine and the difference in angle is due to the trailer sitting higher on one side than the other. I would still verify that the spring hangers are the same distance apart on both sides of the trailer, and that none of the other trailer components are not worn out. For the 3-Leaf Spring # SP-220275 that you referenced the recommended distance between the hangers is 25-3/4 inches

  • Will these Leaf Springs work for my Tandem Axle Boat Trailer?
    To make the proper recommendation for your trailer we will need to know the weight capacity of the trailer axle or axles, and the three measurements on our trailer leaf springs page, see the link (scroll down to Replacing Springs Section). The Trailer Leaf Spring 1750 lbs, 3 Leaf, item # SP-220275 may work on your trailer, but if the weight capacity is too low or high you will have reduced towing performance and possibly an unsafe condition.

    The 60/40 measurement to use when initially placing axles is from the center of where the ball fits into the coupler to the very back of the trailer.

  • Can 1 Independent Axle be Added to a Single Axle Trailer
    I think that the best solution is to replace the axle on your trailer with a higher capacity one. Otherwise you would likely have to relocate the axle it has now before adding a new one because the spacing between the axles has to be conducive for supporting weight and safety. This means suspension hangers would also have to be relocated by cutting them off and welding on new ones. Going with a higher capacity axle and installing it in the same place as the old axle would solve all those...

  • Where to Start When Trying to Determine Axle Placement on a Boat Trailer

  • Can a Tandem Axle Trailer Be Built with the Axles Mounted Independently of Each Other
    There are certain axles that can be mounted independently of each other on a tandem axle trailer. Torsion axles and Timbren Axle-less systems fit the bill because they mount independently. Leaf spring axles though would require spacing the axles too far apart and that would cause tire wear problems. The biggest issue would be the front axle tires dragging on the ground (scrubbing) when turning because of the increased distance between axles. Torsion axles and Timbren systems can be mounted...

  • How to Determine Where Suspension Should Be Installed When Building Tandem Trailer
    When installing trailer suspension you will need to completely mock up the axle to make sure you have the correct tongue weight. One concern is you saying that you are converting the trailer with this new suspension. Changing suspension and adding an axle will not increase the load carrying capacity of the trailer. The best way to install your system is to put the suspension all together and clamp it in place with the rear shackles at a very slight angle rearward when the trailer is lowered...

  • Can Heavier Rated Leaf Springs than Needed be Used on a Trailer
    If the leaf spring part # SP-220275 that you referenced matches up dimensionally to what your trailer has and has a capacity that is 400 lbs more than needed it would work just fine. Having a bit extra capacity for the leaf springs would not cause an issue at all. At worst it may cause the trailer to bounce a bit more unloaded.

  • Why Are Leaf Spring Bushings Narrower Than the Springs
    The bushings aren't designed to extend past the edge of the spring. When the shackle bolts are tightened, they're not meant to be drawn down so tight that the spring hanger or shackle is in contact with the side of the spring eye. That's why the spring/shackle bolts will typically have the knurling on one end, so they're locked into place.

  • Making Sense of Trailer Leaf Spring Capacities
    Trailer leaf springs like # SP-220275 have 2 ratings. One rating is for the spring itself, in this case 1,750 pounds for SP-220275. The other rating is the capacity of the axle it would go on. So for spring SP-220275 it would go with a 3,500 pound axle. So to recap, the spring itself is rated for 1,750 pounds for use on a 3,500 pound axle (when using a pair of springs per axle). I have included a link to our help article on double-eye spring suspension for you.
