50mm Drop Tow Bar Receiver Hitch Kits 3.5t | Trailers, Caravans & Campers

A tow bar receiver hitch kit is a set of components that allow you to attach your trailer or caravan to your tow vehicle.

Couplemate™ Trailer Receivers are made from Solid Cast Iron, improving the connection strength between your trailer and tow vehicle.

Over time, cast steel products are superior to fabricated/welded products. Welded ball mounts and hollow receivers can distort under off-road conditions and shock-loading events on the highway. When inverted, hollow hitches are at a greater risk of deforming.

Couplemate™ recommends that all off-road couplings use a solid cast receiver hitch. This includes:

Key BenefitsAustralian Made and Owned.

  • Stronger connection between your trailer and tow vehicle.
  • It can be safely inverted to obtain additional height.
  • Long-lasting product that will withstand tough towing conditions.
  • Purchases directly support the Australian economy.

The Couplemate™ Trailer Receivers are one of the last trailer hitches on the market to be Australian-made. The receiver shanks are cast in Sydney, drilled and machined in our Brisbane warehouse.

What is a Tow Bar Receiver Hitch?

Your tow ball receiver is the bar in your tow vehicle and connects to your trailer coupling, usually by a tow ball or a tow pin.

Hitches are designed with different towing capacities, making choosing the right one based on your requirements crucial. Ensure that your trailer weight is not higher than your towbar rating (e.g. if your tow rating is 3.5t, then the rating of your hitch must also be 3.5t).

For more information on the different kinds of trailer hitches, read our article: “Choosing the Right Hitch: Guide to Tow Ball Receivers.”
