What is a Leaf Spring Trailer Axle?

There are two main types of trailer axles: Spring axles and torsion axles. Spring axles are the most popular axles used on trailers today.

A leaf spring trailer axle is made up of a series of slightly curved metal strips that are called “leaves” that sit on top of each other in several layers.

The curve in the metal leaves is designed to absorb the bumps of the road.

Advantages of Leaf Spring Trailer Axles

InexpensiveSpring axles are less expensive because of the ease of parts availability, shipping, and installation.

Easy to install – The simple design of spring axles doesn’t require welding to install. They are shipped with the springs and components already attached to the axle, so it just needs to be fastened onto the mounting brackets with bolts.

Easy Maintenance – If something breaks on a spring axle, it can be replaced, unlike the torsion axle where the entire axle has to be replaced if one thing breaks.

Better tire wear – Tires will wear evenly because spring axles usually have a built-in equalizer. This helps with spreading the load evenly as well, which is important on multi-axle trailers


Wear faster – The way spring axles are designed with metal-on-metal can cause them to wear out faster, which leads to more frequent repairs.

Rougher ride – Spring axles will give a bouncier ride, especially with an empty load, compared to torsion axles
