Parts Needed to Change Trailer Suspension from Underslung to Overslung

Question

Question:

I recently built a large deck over flatbeb/ dump trailer out of an old tandom axel travel trailer chassis. I added in 2x6 tubing and remounted the equalizers, but there still is very little room between the top of the tires and the bottom of the deck on the trailer. Currently, the leafsprings and axels are under-slung. Can I change these to over-slung to give some more clearance? If so what part/ conversation kit do I need?

Yes! We have exactly what you need to move your axles so that they are under your leaf springs.

If you have 2-3/8" diameter axles use part # K71-384-00 or you can use part # K71-385-00 for 3" diameter axles. These will raise your trailer equivalent to the diameter of your axle plus the height of the leaf spring stack.

Trailer manufacturers don't usually keep a record of parts like these that they install at the factory, so I cannot be sure as to the exact length of the shackle strap that would have come originally on your trailer. With this in mind, a…

Moving a trailer axle from being overslung to underslung really isn't a big ordeal. It's basically just welding on a new spring seat on the other side of the axle and then using the hardware upside down. We sell kits for this. The…

You can mount trailer axles above or below the leaf springs. The difference is just the amount of ground clearance that the trailer would end up having. The biggest advantage with the spring below the axle (trailer will be lower) is that you would…

Technically, a trailer rated for 10,000 lbs can have 5 lug hubs. They are most common on 3,500 lb axles but can be used on the rare 4,000 lb axles as well. You could have a gooseneck or 5th wheel trailer with the 10,000 lb capacity and tandem axle 5…

It's definitely possible to upgrade a trailer's axle rating to a higher rating by just swapping the axles. To pick out the correct axle you'll need to measure the distance between the hub faces and the spring seat centers and you'll…

We do have a couple of bolt-on spring hangers #CE14017G and #CE14016G but they are designed for slipper springs and not double-eye springs like #e77SR. Its not likely that professional welder would charge that much. You might be able to find one…
