Tow with Confidence: ADR-Approved Mega Adjustable Tow Hitch

The Couplemate™ CM529 is a Premium-Cast Mega Adjustable Tow Hitch, specifically engineered to be the most robust hitch on the Australian market. Designed to handle caravans and trailers up to a 3500kg ATM, this adjustable tow hitch receiver kit is a versatile and reliable way to tow a trailer or caravan.

Adjustable Tow Hitches allow you to have precise control over the height of your tow ball, which impacts the height of the drawbar when attached to the tow vehicle. This flexibility allows you to conveniently tow different trailers at different heights.

The ball mount head provides up to 90mm of drop and up to 190 mm of rise (centre of tow ball to centre pin). This is particularly useful for a range of towing applications, from low boat trailers to high-set camper trailers.

Updated Tow Heights CM529

The CM529 Adjustable Tow Ball Mount features a 190mm Rise and a 90mm Drop.

How does this compare to other Adjustable Hitches on the market? Most other tow hitches have a 114mm Rise and a 90mm drop, measuring from the centre pin to the tow ball plate.

When measured this way, the Couplemate™ CM529 offers a 140mm rise and a 140mm drop.
