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.

These six leaf double eye 24 7/8" leaf springs worked perfectly replacing the ones on my 40 foot Big Horn 5th Wheel. They fit exact as you can see in the photo attached. You might also notice the Provider trailer tires that I also bought at etrailer - Great tires, they'll carry the load. I was amazed that all four leaf springs came in a heavy duty cardboard box, the UPS Ground guy got his workout! This is the second set of springs I've order from etrailer and both orders came quickly and on time as promised. Etrailer.com helps you follow the shipping route as they move to your location - great help! I'll definitely use them again.


Comments
Its been a year now and the leaf springs have got their workout. Weve taken about 5 trips over this past year, one over 2400 miles, and the springs have held up well! Trailer is still balanced and tracks true. Im very pleased with them.

Bolt in replacement for my broken spring, installation of the springs was easy and took about 20 minutes a side. I have had these in for over 10,000 miles no issues. I would recommend to not use the nylon bushings. I replaced them with bronze bushings for longevity. I am pleased with the parts and the service from etrailer.

Still going strong, we put on another 8K or so miles on the trailer no issues.

I had quite a run of issues with spring replacements. The original springs flattened out. So I tried some 8000lb springs which didn’t work at all. They were 3/4” to long and that didn’t work. So then I ordered some springs on line and installed them and about 3500 miles later one of them broke. They were 1/2” longer than the originals. I ordered the 24 7/8” springs from etrailer and installed them last summer and made my cross country trip to Florida from Oregon. So far they are holding up and functioning properly. I do wish there were some 24 7/8” springs with one more leaf in them. I am considering installing some type of air bags to give the suspension a bit more support.

Working well with our 2018 GD Solitude 310 in conjunction with the Moryde CRE3000. Night and day difference between this and the Dexter EZ-Flex suspension and junk leaf springs our camper came with. These leaf springs are riveted together. Not clipped together like the Dexter ones that failed on us.

Placed my order on Thursday at 8 AM. Order was received on Friday at 3:30 PM. The lady that took my order was friendly and answered all my questions. I ordered 4 PR6 ,3500 lb. springs with U-bolt kits for 6000 lb . axles. The old set up had 3000 lb springs, 1 main leaf had broken and 2 were almost straight. I had 7/16 difference in center line measurements from side to side. After installing the new springs and U-bolts the center line measurements are within 1/32 side to side. I will tell everyone about your company. Great service and products. etrailer.com is the place to go.

This suspension kit was perfect for my Forest River Wolfpack. If you have a 40' camper you need this. It raised the rear height giving more of a level pull, stiffer turns, better off-road less roll and less bounce in the camper when setup. All campers are junk quality, so do yourself a favor and upgrade your suspension.

Horrible quality parts! Poor customer service after the sale! The were very helpful until I bought the parts. I bought these springs and wet bolt kit because the bushings were wore out in my two year old fifth wheel camper, and the play in the suspension was letting the tires rub the frame. The new parts fixed that problem. It towed better than it did when it was new. But after about 5 thousand miles, these poor quality springs are now splayed out and making a lot of noise. I emailed and called etrailer and they said it's a big problem and I shouldn't be pulling it, but it's a problem with the trailer alignment not their parts. This was never a problem until I put the new etrailer parts in less than a year ago. My tire wear is very good (If the alignment was bad, my tires would show it). My measurement of the axle alignment appears good as well. I believe it is a poor product they will not stand behind. The brackets that hold the springs together are very thin and poorly made. I am very disappointed with etrailer!


Comments
The Leaf Springs are junk. They splayed horribly since new, I went back and forth with etrailer and it went nowhere. When I sold the trailer last summer, they were starting to look flat already. Very disappointed in the springs. I wish I would have bought a better quality. Also very disappointed in etrailers customer service on this one. I havent bought any trailer parts from etrailer since.

Product was as described. Swapping out original 5200 LBS sagging springs on my 2005 Wanderer Wagon toy hauler to carry quads, a 4 seater UTV and "lift" slighty to avoid continuing to scrape off plumbing. Won't be overloading but wanted that extra capacity to keep the trailer sturdy so not to sway a lot and to hopefully keep the height up. I will be flipping the axles in the future but for now its up to the springs. Part appears to be very sturdy / well made and of good quality (wish these were US made though). These are not installed yet. I just received the product last night. I will be replacing my spring hardware soon to the grease able pieces. Especially after seeing the nylon bushings. To me this seems to be the only possible weak point. Seem thin. This is my 2nd or so purchase from etrailer and just with customer service alone I will MOST definitely be purchasing again. As well as recommended etrailer to friends. Josh D

Springs have been installed and make the trailer feel more sturdy. Didnt give much lift as I hoped but that was wishful thinking. Will probably use these same springs on my flatbed car trailer as well. I would recommend these to anyone.

Installed a set of these on my 38' toy hauler on the passenger side because the frame was bent and twisted the springs then was fixed. Make sure you retighten the u-bolts after a few miles. 1st spring fell apart by the center bolt coming out after about 1800 miles losing 2 leaves. Put old spring back on. 2nd spring came apart after about 4000 miles with center bolt nut coming off and losing 2 leaves. Put old spring back on. This time re-tightened both springs after a few miles. Good to carry spare parts with me and the tools to fix! Put another 10,000 before reaching home. Going to order another set as backup. So remember to tighten enough and check after a few miles.

I purchased these springs for a Belmont machine trailer that I broke a spring on, I replaced all 4 springs the quality is better then OEM. I am very happy I just installed them today the biggest issue I had was when I watched the installation video it showed a much smaller single axle trailer on a lift as well. I was going to make a video on the procedure I used after I struggled with some of the bolts on the first one I found a much easier way as I have dual axles I jacked the trailer up, put a jackstand under the axle lossened the two eye bolts then took off the 4 nuts for the u brackets. Then the eye bolts came off and bam done.. I had to cut two bolts so I suggest you buy spare bolts when doing this job I had a hell of a time finding a local place that carried the exact size. Overall great product etrailer has never let me down!

First the Good- The 4 leaf springs and mounting hardware that I ordered for a custom trailer set up arrived quickly and with all the correct equipment. It was with the free shipping so it took about 5 business days to reach me. That was over all amazing for half the cost over local retailers in my home area. So the good was better then good... down right amazing even. Now the not so good- I am not trying to be picky but I received 2 boxes with a total of 4 leaf springs and 2 hanger kits and some mount plates. 1 box was perfectly packaged with plenty of stuff inside to maintain accountability of all items inside. The other box was a train wreck with 2 of the leaf springs half out of the box. Leaving the paint all scratch up. Again in the hanger kits that I order 1 box was perfectly packaged while the other one was just thrown in together making it difficult to account for all items. Overall I am happy with the products I ordered I know that leaf springs are not dainty, fragile things. So I am not too concerned about the integrity of them. However I would recommend to etrailer.com to improve on packaging so items do not get lost or damaged in the future.

Arrived quickly. Although the box took a beating everything was in it. Would have been nice if shackle bolts were included. Had to run to [retailer] for those. They are holding up well under my 36' toy hauler 5th wheel that the women insist on over loading every time we go anywhere.

Received my leaf spring today. Packed very securely and in good condition. I plan to carry it as a spare in case one breaks on me. Thanks for the upgraded shipping. Much appreciated. I would really like to upgrade all four leaf springs from 3500 to 4000lb but I did not see them on your website. Do you have those available?

  • How to Determine Correct Replacement Leaf Springs for 7,000 lb Axle
    I can give you some guidance on how to determine the correct replacement leaf springs, and you are right that replacing all four of them at the same time is a good idea. What you'll need to do for double-eye springs (which is what I assume is on your 2017 Keystone Fuzion) is measure from the center of one eye to the center of the other eye and get a match as close as you can. Just take into account that the springs may have elongated a bit over time. For example, the only double eye...

  • Replacement Leaf Springs on my 2016 Forest River 27RR
    With those measurements in mind and the fact that your camper has a Gross Vehicle Weight Rating (total max weight of camper, gear and water loaded) of almost 9,000 lbs you have one solid choice. Using the 4-Leaf Double-Eye Spring for 6,000-lb Trailer Axles part # SP-221275 offers the 25 1/8" eye to eye you want and uses the same 9/16" bolt size. These springs are rated for 3,000 lbs. each so in total they will give you 12,000 lbs. of capacity. Now your camper is only rated for 8,940...

  • Could Replacing Older Trailer Leaf Springs Gain Additional Height to Trailer
    Most likely your springs are sagging a bit if they are over 10 years old. Since it's a good idea to replace those anyway that's probably a good place to start. In the 7,000 lb capacity we only have one size of 24-7/8 inches as part number # SP-198275. Even going with a new set of 6k springs will be an upgrade. For that we have a few lengths like part # SP-111275 which is 25-1/4 inches long, # SP-053275 which is 26 inches long, or part # SP-221275 which is 25-1/8 inches long.

  • Can 24-7/8" 7000lb Leaf Springs Replace 25-1/4" Leaf Springs On 2015 Grand Design Solitude?
    As long as the current leaf springs on your 2015 Grand Design Solitude 305RE with 7000lb axles are 25-1/4" long with no weight on the spring, then the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles - 24-7/8" Long # SP-198275 would be the correct replacement. It is pretty typical for springs to stretch as they wear, so being 3/8" short will not cause an issue. I included a video of the # SP-198275 for you to take a look at.

    A 7,000 lb trailer spring can be used on a 6k rated axle but you should note that this will not give you more capacity. A trailer setup is only rated as high as it's weakest component. So while you may have 7k of spring rating with the # SP-198275, you would still only have 6k of axle rating.

    Most likely the measurement is 25-1/8 inch as that is a common size.

From front to back your hangers for that 20-3/8 inch spring like # SP-169275 will be 24-3/4 on center then 29 inches on center and finally 24-3/4 inches on center. This will put each of the 3 axles 28-1/2 inches on center. I've attached a photo to assist. This is all based on 7-3/4 inch curved equalizers and 2-5/8 inch long shackle straps. These are found in the Triple-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4"...

  • How Much Clearance is Needed Between Trailer Axle and Trailer Frame
    Since your axle is mounted on top of the leaf spring you will want between 2 and 2-1/2 inches between the top of the axle and the trailer frame. You will also want 3 inches of clearance between the top of the tire and the fender. Check out the FAQ article on trailer suspension I attached also.
