Some trailers have Torsion axles and some have spring axles. What is the difference?
[BACK TO TOP] Spring axles have been around for about 200 years and are still widely used in small utility trailers and cheaper trailers of all kinds. They aren’t bad, but Torsion axles are better. Torsion axles ride smoother, have inherrent shock absorbtion qualities and have fewer moving parts, therefore less maintenance problems. An axle may come with a special lubrication system, such as Dexter Axle Company’s “E-Z LUBE” hubs, making lubrication far easier. They cost more, but only about $15-$20 per axle. A Torsion axle is a simple steel shaft mounted in rubber inside a steel tube. There is a trailing “arm” on each end of the axle with a normal spindle to mount a hub. It is a better idea that has become the predominantly used axle in better trailers.
