Trailer Coupling selection is crucial for all types trailers. If you are going to paint your trailer or parts then go for a painted coupling otherwise grab a galvanised one.

Override couplings can bend on the main shaft if the reversing lock is not engaged when reversing. So save yourself a few bucks and always engage the reversing lock on your override coupling and always use high tensile bolts when installing these couplings as they can be used under extreme load conditions.
