The Ark Bolt On Stem Adjuster is galvanized to be able to deal with the harsh salt water punishment that our trailers have to deal with from year to year. It comes standard as a 3-inch, 75mm long bracket with a bolt included. Designed to be fitted to your trailer to enable the addition of rollers, or even skids, these will help you adjust your trailer exactly as you need to. Due to our great range of rollers, skids, bearings, BCF have everything to keep your boat going on and off the trailer as easily as possible.
