The Al-Ko AK 351 Profi ball coupling is a high-quality ball coupling for trailers with a permissible total weight of up to 3500 kg. Thanks to the maximum drawbar load of 350 kg, it offers additional stability and safety. The coupling is equipped with a safety indicator that reliably shows whether the connection has been made correctly. In addition, an integrated wear indicator makes it easy to check the condition of the coupling. It is suitable for tie rods with a diameter of 60 mm and can be securely fastened using two holes for M16 bolts with a hole spacing of 54 mm. Another feature is the preparation for a built-in lock, which provides additional theft protection.

Frequently asked questions about this product
Ball head on the towing vehicle: The new ball head has a diameter of 50 mm; the wear limit is 49 mm. Measure in several directions using a calliper — the ball wears down in an oval shape, and even a single point measuring less than 49 mm means it needs replacing.
Tow ball coupling on the trailer: Signs include noticeable play on the ball, rattling whilst driving, or a coupling that no longer engages properly. Many couplings have a wear indicator on the handle — if the pointer is in the red zone, it needs replacing.
Assess both together: a new coupling fitted to a worn-out ball will continue to rattle.
Lubrication: The ball and coupling wear out much faster if left dry. An important exception is anti-sway couplings: their friction linings must remain grease-free; in this case, only the ball is cleaned. Grease on the linings renders the anti-sway damping ineffective and ruins the linings.
A worn-out pair will be flagged during the annual general inspection. Replacement: Ball couplings and accessories.
