Genuine ALKO Towball
This towball is manufactured by ALKO and machined to allow free articulation of the coupling head.
This ball should always be used if an ALKO stabiliser coupling is fitted to the trailer.
Please note that to ensure proper function of the ALKO stabiliser, all the paint on the 50mm ball should be removed using emery cloth or a similar substance. The ball is designed to be used dry and grease free.
