How to Install Lippert Correct Track II on Trailer Without Adding Height to Trailer

Question

Question:

This looks like a great thing, and I would love to install it, as my triple axle 5th wheel wears the inside tread off on the left tire of the rear axle. The tire on the right side of that axle is fine. I have been told that the only way to align my camper is by bending the axles, unless you install the correct track. Unfortunately, my 5th wheel is 13-3inch tall when loaded and on the road. Adding an extra 2inch would make it too close for comfort under the 13-6inch bridges. Do you know of any alternatives?

You've got a pretty tall trailer! And I totally understand not want to be just an inch below the height of bridges. Your current height is scary enough...

So what we need to do is come up with a way to lower your suspension so that we can offset the additional height (2 inches) that the Lippert Correct Track II # LC87320 would give your trailer. Are your axles above or below your leaf springs? If they are below the springs you can move them to be above the springs and that will lower the trailer a few inches (basically the thickness of your axle), so that you can install the Correct Track and have it not be too tall.

The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under Kit, # K71-384-00. These kits can be installed without welding but the manufacturer strongly recommends having the new spring seat tacked in place on the other side of the trailer axle.

Some refer to this process as "flipping the axles," but since axle has a slight bow to it you can't just flip them and reinstall them under the springs using the same spring seats. You have to install new spring seats on the opposite side of the axle so that it can be moved below the spring.

If this isn't an option for you I would recommend you find a shop that near you that can do trailer alignments and have them see what they can do.
