Springs, Caravan, Trailer

Springs for Caravan, Campers and Trailers – 45mm and 60mm wide

Leaf springs for caravan and trailer models are designed to cushion the loads from your camper or caravan and successfully absorbing bumps you encounter.

Some Crucial Information On Caravan And Trailer Suspension

Leaf spring suspension for caravans and trailers aren’t all the same. These can vary even when made by the same manufacturer.

For example, Jayco and Coromal leaf spring suspension vary from model to model.

Locating the spring type apt for your needs is easy. However, we’ll need some information first; this will help us identify the correct parts immediately.

  • Length measured from eye-to-eye or eye-to-slipper.
  • Number of Leaves.
  • The thickness of each leaf.
  • Measurement of the centre bolt.

We carry the standard 45mm and 60mm-wide springs. We also stock other widths that are a little harder to get.

Common Caravan And Trailer Suspension Issues

Breakages occur in two places:

  • Rupture near the eye and
  • where the centre bolt goes through the leaves.

Broken suspension at the eye is usually a sign of overloading. In this case, you’ll need to upgrade to a heavier spring.

If your mechanic does up your fish plate incorrectly, your spring will break at the centre bolt. Do not tighten u-bolt nuts up with a rattle gun.

When the fish plate has more tension on one side than the other, the spring is unevenly balanced. You’ve likely loaded more weight on one side of the spring than the other. The result is a break right down the middle.

The fix, turn the fish plate upside down and tighten it by hand. Take care you don’t bend the fish plate. Retighten after 200 km.

Upgrade begins replacing Broken Caravan Suspension.
Wrong Hanger Location causes Suspension Problems.
