In order for you to realize more clearance under your trailer, using torsion axles with down degree angles will give you more clearance.

On a system that has a 10 degree up axle, the center line of the spindle to the bottom of the trailer frame is approximately .96 inches. That is based on a newer system. If you have an older system on your trailer that measurement may be much less.

For a 10 degree down you would have a difference of 2.08 inches. For 22.5 degree down, the difference would be about 3-1/3 inches, and for a 45 degree down torsion axle, the difference could be 5.28 inches.

If you know how much clearance you need for your trailer, you can use those numbers to give you the best fit for you. You should realize that raising the trailer for more clearance will introduce more trailer sway by raising the center of gravity.

We would definitely be able to upgrade to a higher capacity Leaf Spring or Silent Ride set up. That being said, we do not carry torsion axles, so we do not have a bolt on upgrade available. The axle #8327820-EB would upgrade you to 5,200 pounds per…

It is certainly possible for any axle to wear out enough over time to need replacing. Since the suspension is built into a torsion axle if the suspension part was to wear out pretty much the only solution would be to replace the axle. If the…
