3.5t Al-ko off-road coupling is rated at 3500 kg. The Alko coupling offers a lower profile at the tow ball than most other off-road couplers.

The Couplemate 3500kg high shoulder tow ball is a good companion for use with this coupling.

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 heavy ground.
