About This Product

The SPARTAN Torsion-Flex Gooseneck Coupler is designed to focus on and increase the comfort of the driver. This innovative coupler utilizes TORSION-FLEX technology which isolates the truck from the trailer creating a much smoother, safer, and more enjoyable towing experience. 

The SPARTAN coupler is designed to be used with flatbed, utility, and enclosed gooseneck trailers, and is guaranteed to give you one of the best-cushioned rides on the market. Some 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 so 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.
