These devices were popular before the invention of tow ball scales. Tow ball scales enable owners to perfectly balance their caravans or campers.

A major part of balancing your rig is to level your rig with this adjustable tow hitch from Pro Series. Also, ideal for mounting load levellers.

This article shows you how to better balance your caravan thereby eliminating the need for load levelling devices.

The purpose of a drop ball mount after insertion into the tow ball mount is to raise or lower the towing height.

  • A low towing position causes the tow vehicle suspension to be pushed down during braking. As a result, reduced steering occurs.
  • Towing position pushes the suspension up, reducing traction on the rear wheels.
  • Invert the Hayman Reese® 50mm Adjustable Receiver to increase the height of Tow Ball.
  • Secure the adjustable mount into position on the tow vehicle with a hitch pin.

Both of these positions above are extremely dangerous.
