The SPARTAN Torsion-Flex gooseneck coupler is designed with the comfort of the driver as the number priority. This revolutionary coupler utilizes TORSION-FLEX technology which isolates the truck from the trailer creating a much smoother, safer, and more enjoyable towing experience. The SPARTAN is designed to be used with flatbed, utility, and enclosed gooseneck trailers and it will give you the best-cushioned ride on the market. Hotshot customers who tow flatbed gooseneck trailers on a daily basis have reported fuel savings and decreased tire wear. The SPARTAN coupler is taller than a standard coupler, and it is important to measure the distance from the bottom of your current coupler to the retaining pin. If clearance is an issue, the PEGASUS model may be a better option. This unit is designed for lower profile trailers such as horse, race, or any other low clearance gooseneck trailers.
