BCF has you covered for all things trailers, as well as everything Boating Camping and Fishing. The vast majority of trailers have a jockey wheel, but have you ever taken much notice of it? There are only really 2 mounting options for them - either welded on, or more commonly bolted. Ark Jockey Wheel U Bolts are designed to fit around the draw bar of your trailer and bolt through the holes on your jockey wheel mounting plate. These zinc-plated 75mm x 50mm U Bolts come complete with spring washers and nuts.
