What Are The Differences/Benefits Between Leaf Springs And Torsion Type Axles?


Majority of trailers have leaf-spring axles. However, torsion axles have been increasingly used due to their superiority in longevity, stability, and safety. Leaf springs provide cushion in a trailers suspension by attaching to axles with U-bolts. On torsion axle trailers, the cushioning function is built into the axle. Self-contained and sealed, torsion axles resist rust and corrosion better than traditional leaf spring axles. Torsion axle trailers lower the center of gravity of the load you are hauling, thereby providing more stability for the trailer, but if you have a flat tire a torsion axle requires a spare wheel before you are able to continue pulling the trailer. A torsion axle trailer also has the drawback of a low variable-rate, giving less flexibility when loaded or going over harsh terrain. Some experts say that leaf springs are the better option while torsion axles are the best option.
