Finally, consider the following when selecting a coupling:

  • Type of brakes used?
  • What is the maximum total loaded weight of the trailer planned to be?
  • Can I use a 50mm ball or do I need a ring-type attachment?

High Shoulder Tow Balls

Extreme angles can cause the Al-ko® off-road coupling to contact the tow hitch causing damage.

Consider a high rise tow ball to give extra clearance over the heavy ground.
