Blue Ox 750 lb Kit Spring Bars BXW4006 14-5276

750 lbs. Spring Bar Kit. If you switch trailers, do not buy a new hitch, just buy the bars. All head assemblies for SwayPro models are the same, but interchangeable spring bars allow an increase or decrease in capacity for proper towing. Beveled ends lock into place with a spring pin without grease for clean use and storage.
