If you need a straight-up tow ball for the daily or the touring rig, the Ark Chrome Tow Ball Long Shank 7/8 x 80mm 2.5t 50mm gives you a standard 50mm ball with a rated capacity of 2500kg. The 22.23mm diameter shank runs to 80mm long, so it works well with thicker tongues and common bolt-on hitches on utes and wagons.

The chrome plated finish covers the full 50mm ball and 80mm shank to handle road grime, spray and surface rust better than bare steel. The 22.23mm threaded shank suits standard nuts and washers, so swapping it onto an existing tow bar setup stays straightforward. With a 2500kg rating, it is a smart buy for camper trailers, box trailers and smaller caravans across typical Aussie highway and gravel conditions.

Q: What size coupling does this tow ball suit?

This tow ball suits standard 50mm trailer couplings. Most Australian box trailers, camper trailers and many caravans use a 50mm coupling head, so this ball will match those setups. Always check the stamping on your existing coupling to confirm it states 50mm before fitting. Using the correct size ball helps keep the connection stable under load.

Q: What size hole do I need in the tow bar tongue?

You need a 22.23mm or 7/8 inch hole in the tongue. The shank on this tow ball is 22.23mm in diameter, so it must pass cleanly through the mounting hole without excess play. If the hole is badly worn or oversized, replace the tongue before installing the new ball. A snug fit helps keep the hardware tight.

Q: Is the shank long enough for weight distribution plates?

The shank is 80mm long, which suits many thicker tongues and common bolt-on plates. Measure the total stacked thickness of your tongue and any plates to make sure the 80mm thread gives full nut engagement. You want several full threads showing past the nut when tightened. If your stack is thicker than this, consider a different tow ball.

Q: Can this tow ball be used off-road?

This tow ball is rated to 2500kg and built for general towing use, including unsealed roads within that capacity. Off-road work can add higher impacts, so keep trailer weight within the 2500kg rating and inspect the ball and nut regularly. Replace the tow ball if you see visible wear, deep scoring or deformation on the 50mm head.
