MTNTK Performance Tunnel Cut - Tunnel Shortening Kit MTNTK Performance is pleased to announce new for the 2020 snow season the MTNTK Performance Tunnel Cut – Tunnel Shortening Kit. As snowmobilers search for the ultimate in riding performance any modifications that decrease drag and improve handling in the snow are paramount. Reduction of drag at the rear of the sled by shortening the tunnel and or the snow flap is a current trend among the bravest to get the most out of their machine. By reducing the amount of the chassis that could potentially drag in the snow the sled handling is improved especially when performing advanced maneuvers on the hill such as side-hilling, and reentry turns especially in deep loose snow. The MTNTK Performance Tunnel Cut – Tunnel Shortening Kit allows owners of Polaris mountain chassis snowmobiles model years 2011 thru 2021 to perform the modification without welding. Currently Polaris uses a welded extrusion heat exchanger that doubles as the chassis tunnel support and structure. Any modification to this structure also modifies the cooling system and potential for leaks becomes evident. The MTNTK Performance Tunnel Cut – Tunnel Shortening Kit allow the customer to shorten the tunnel without the need for specialized welding or cutting tools and allows for a professional finished appearance, enhancing the snowmobile in the process. This kit was designed as a reasonable cost solution to shorten the tunnel on late model Polaris snowmobiles. The basics to installing the kit are as follows in a few simple steps: draining the coolant, cutting the tunnel off square with no complicated cuts, cleaning and deburring, installing the extrusion adapters with adhesive and cross over hose, installing the tunnel cap/ hose protector, and refilling the cooling system.
