Lazy axles are a popular combination for a 750kg trailer.

Axles without brakes are manufactured in a variety of sizes from 39mm Round for a small box and jet ski trailers up to 3t for farm trailers.

750kg is the limit for unbraked axles. Larger axles up to 3t are available to be used on farm applications. An example is a 6t tandem axle with no brakes.

39mm round axles are at their maximum rating and cannot be upgraded.

Furthermore, the addition of Landcruiser wheels de-raters 39mm round axles by 20%. Therefore the new rating of a 39mm round would be 600kg.

When considering an upgrade to a box trailer, brakes will be required on at least one axle.
