Parts Needed to Convert Overslung Trailer Axle to Underslung

Question

Question:

I have a 2005 Fleetwood Scorpion S1 pop up camper. The trailer was overslung when I bought it a few years ago I am not sure if that is standard and I find that makes loading toys onto the deck and climbing into the trailer more difficult than I would like. What would be needed to change this trailer to an underslung setup?

We have kits for that but you would need to know the diameter of your axles to determine which kit you would need. If the axle diameter is 2-3/8 inch which is common for 3,500 lb axles the kit you would need is the part # K71-384-00. If instead you have 3 inch diameter axles you'd want the part # K71-385-00.

If your U-bolts are still in good shape you could reuse them. You would just need a new spring seat designed for your diameter axle. I attached a link to a page that has all of the spring seats we carry. If you select your axle diameter from the…

Answer 10

You are indeed right to think this way. When picking out the appropriate leaf springs for your custom built trailer you will want to choose them based on what the actual loaded weight of the trailer will be. Just make sure that the leaf springs have…

A trailer can bounce if there is not enough weight on it. You see this particularly with utility trailers that are empty. The tire and wheel size would not automatically cause a trailer to bounce though usually you see smaller tires on smaller…
