This Ark Electric Coupling 50mm 3500kg hooks a trailer with a 50 mm ball setup to a tow vehicle rated to 3500 kg. The gear suits caravans, box trailers or campers that sit near the 3000–3500 kg mark and use electric brakes. The built-in parkbrake arm ties into your existing brake hardware so the trailer stays put when you unhook after a 200 km highway run or a short tow to the local tip.
The coupling is rated to 3500 kg and shaped for standard 50 mm balls used across most Aussie tow rigs. The adjustable screw lets you dial in clamping tension across a few millimetres of ball wear, keeping the connection tight during 100 km/h travel. Steel construction and AS4177.3-2004 compliance keep it within Australian road rules. For anyone wanting solid towing gear that works trip after trip, this is a smart buy.

Q: What size tow ball does this Ark electric coupling suit?
This coupling is made for a 50mm tow ball. That is the standard size on most Aussie tow vehicles and towbars. Using the correct 50mm ball helps the adjustable screw bite properly. This keeps the hitch connection firm and helps reduce unwanted movement while towing.
Q: What is the maximum trailer rating for this coupling?
The Ark Electric Coupling is rated to 3500kg. Your trailer ATM and towbar rating must also be 3500kg or less. The lowest rating in your setup always applies. Staying under that figure keeps you within the intended working range of the coupling and local road rules.
Q: Does this coupling include a parkbrake function?
Yes, the unit incorporates a parkbrake mechanism. The lever is designed to connect to compatible trailer brake hardware. When set correctly it holds the trailer in place during stops. You should still use wheel chocks on slopes or loose surfaces as part of normal trailer practice.
Q: Can I lock this coupling when the trailer is parked?
The coupling includes a padlock facility. You can fit a suitable padlock through the provided point to help deter casual theft or tampering. A lock does not replace normal security steps like wheel clamps or parking in a secure area. It simply adds another barrier for anyone interfering with the hitch.
