The following guide shows How to Measure Trailer Axles. One of the most common questions from customers buying new trailer axles is “How do I measure my axles?”  

How to Measure Trailer Axles

Measuring your axles isn’t tricky, but it does depend on the type of axles you have. The two most popular types of trailer axles are spring and torsion.

Measuring Spring Axles

When measuring spring trailer axles, you must be familiar with the hub face, the spring center, and the overhang.  Obtaining the hub face measurement involves measuring the space between the outside faces of the hub.  To identify the hub faces, look for the outer part the wheel connects to and the bolts extend from. The space between your hub faces is your hub face measurement.  Spring axles also require you to measure the spring center. The spring center is the measurement from the center of one spring to the center of the other. The last measurement you will need for your new trailer axles is the overhang measurement. To measure the overhang, you need to measure the space between the hub face and the spring center. 

We suggest watching the video guide below for more information on measuring spring trailer axles.


Measuring Torsion Axles 

For the most part, measuring torsion axles follows the same process as measuring spring axles. You’ll still need to obtain the hub face measurement.  However, since torsion axles don’t have springs, you won’t need the spring center measurement. You’ll still need to measure the overhang, but it’ll be taken a little bit differently. Instead of measuring from the hub face to the spring center, the overhang for torsion axles measures the space between the hub face and the outside of the mounting bracket.

How to Measure Trailer Axles – Other Considerations

There are a couple of other things to consider when taking measurements for new axles. Load Capacity: You’ll want to identify the maximum gross vehicle weight rating (GVW) so you know how much your new axle will need to support. Track Length: To precisely measure your track length, measure the distance from one hub face to the other. Essentially, you want to determine the distance between the center of one tire to the center of the other.
