How To Fix Uneven Ride On 6x12 Single Axle Enclosed Trailer

Question

Question:

Hello. I just bought a 6x12 single axle enclosed trailer for work. I’m a carpenter and did a build out for all my tools and one side is leaning a little lower than the other where there aren’t many tools. Is it possible to replace the leaf spring on the heavier side with a more heavy duty one? Or is there some kind of kit to add to the trailer to accommodate the uneven weight load on the single axle?

Hello Kenneth, thanks for reaching out. There are a few ways to address the issue you are having with your enclosed trailer. The first and easiest way to fix the issue is to simply add more weight to the light side of the trailer. Really anything to weigh down one side a bit will help. I have seen people do this with sand bags, cinder blocks or really any heavy material. This way you can fix the uneven ride without having to modify the trailer or replace any parts.

Another option is to use a trailer helper spring like the SumoSprings Trailer Helper Springs # TSS-107-40. These are made for axles rated between 3,000 and 5,000 lbs, so please verify that your axle meets this specification. These are progressive springs meaning they get more firm as more weight is added. This will help add support to the low side and even things out.

It may be possible to add a stronger leaf spring to one side, but this is not something I can really recommend doing. This could cause the trailer to ride funny, it could create sway issues also. This is not something we ever try doing so some of the results are unknown at this point. Leaf springs really should always be equal on both sides.

Thank you Jesse. That’s very helpful information. So for the summo springs, would they be installed to both sides of the axle?

@KenS It is one spring on each side, and installation depends how your axle is set up. If the axle is sitting on top of the leaf spring pack or "underslung" as we call it, the sumo springs install on the side of the axle closest to the shackle. For axles that sit underneath the leaf spring or "overslung" axles, the springs install directly on top of the axle. Your axle is likely underslung since that is way more common, so that will use part # TSS-106-40. Just confirm that your axle is rated between 3,000 and 5,000 lbs and that your spring pack is 1-3/4" wide. Take a look at the video in this link:

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Hey Jason, it's pretty common for replacement leaf springs to be slightly shorter than what they replace as springs tend to stretch/flatten overtime as they wear out so while you are on the right track 3/4 of an inch is a bit too much of a…

Hey Eli! The first thing you want to do is make sure you have brake flanges on those axles. You also need to take a look at the axle tags and find the axle capacity. More than likely they're 3,500 lb axles so I'll answer based on that. If you…

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…
