Will an Over-Under Conversion Kit Fit a Trailer with a Square Axle

Question

Question:

My camp trailer has square tubed axles. Can the kit you stock be used? From the images of the kit, it appears that the kit is for a round tubed axle.

The over under conversion kits like # K71-385-00 only work on round axles. What you can do depends on why you need to raise the trailer. If you need more clearance under the trailer you can replace the leaf spring hangers with longer ones. You have to increase the height equally for all hangers. For example if you go up 2 inches on the front hanger, all hangers must also go up 2 inches.

Raising the height of the trailer can change the ride quality and will make the center of gravity higher leading to the increased likelihood of sway. I have included a link to the hanger main page for you.

If you want to raise the trailer because the tow vehicle is taller and you cannot tow the trailer level you will just need a ball mount with the proper drop. I have included a link to our FAQ article that explains how to measure for the correct drop. I have also included a link to the ball mount main page for you.

Answer 1

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…

I don't see any issue with installing an axle flip kit on a drop axle aside from the shape of the axle as we only offer kits for rounds axle, the Dexter Trailer Springs Over-Under Conversion Kit part #K71-384-00 or part #K71-385-00.

Answer 3

Because a suspension is not static but is meant to articulate, going with longer shackle links won't provide the clearance you're looking for. The best course of action would be to raise the fenders to provide the proper clearance. At the…

Answer 4

You can convert your drop axles to get more height by attaching your leaf springs to the top of the axle. The height you gain will be the thickness of your leaf springs and the diameter of your axle. For example, if your leaf springs are 1-1/2 inches…

Answer 5

We have 2 inch square U-bolt kits like part #CE23103 which you could use, but we don't have spring seats for this axle size. So you would have to remove the spring seats on your axle and weld them on the other side and you'd be have an…

Answer 6

What I recommend, if the trailer has round axles, is an over-under conversion kit. For 3 inch round axles use #K71-385-00 and for 2-3/8 inch round axles use #K71-384-00. This of course will only work if the leaf springs are mounted to the bottom of…

Answer 7

Moving your axles below the leaf springs will certainly give you additional height on your trailer. I can also tell by the picture that you have plenty of room between the tires to go with a taller wheel/tire setup as well. Since you have square…

Answer 8

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…

I do have a few ways for you to lower a camper but it will largely be dependent on what type of suspension you have, leaf springs or torsion. If you have leaf springs and they are positioned above the axle tube, you can flip them with the Dexter…

I have a solution for you, but your 205/65-10 tires similar to the #AM3H390 are going to be the largest size we have available in tire that fits on 10" wheels. In order to get larger tires you would need to go up to a 13" wheel. If…

Answer 11

The tire size 205/65-10 is a suitable replacement for the old tire size 20.5x8-10. I have not heard of a 20.5x8-10 tire mounted on an 8 inch wide rim. Your actual rim width should be 6 inches and the tire itself should be 8 inches wide. A 205/65-10…
