What is the difference between Torsion axles and spring axles?
Today, spring axles are widely used in small utility trailers and cheaper trailers of all kinds. Torsion axles are better- they ride smoother, have inherent shock absorption 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.
