Frequently Asked Questions

What size leaf springs do I need? The first step would be to measure your existing leaf springs. You can then confidently match the springs to your trailer. Refer to our How-to guide below for more information:

How to Measure Leaf Springs

Does upgrading leaf springs increase towing capacity? This is a question that comes up a lot. The answer is both yes and no. Trailers are rated based on their weakest component, which is usually the bearings.

Will longer shackles lift my trailer? Yes, longer shackle plates will increase your trailer’s ride height. We offer two lengths of shackle plates suitable for 45mm springs with 63mm centre and 75mm centre holes. It is important to note that the increase is quite minimal and is not the most effective way to increase height.

You will likely see gains of around 5-8mm by increasing your shackle plate length. For alternative ways to improve the height of your trailer, please call us on 07 3348 3822, and the team would be happy to discuss the most appropriate method for you.

Should trailer leaf springs be replaced in pairs? We recommend replacing both springs to avoid any height difference across either side of the axle. A brand-new spring will always have a stronger camber than an old, worn spring, and if the difference is significant, it will result in additional weight being placed on the older spring. This is not ideal.
