MTNTK Polaris Matyrx Chassis Tunnel Coolers

IN STOCK & SHIPPING DAILY!! We love the new sled but Polaris did not make it easy to upgrade the cooling system on the Matryx chassis. If you have ridden the Matryx you know that it struggles on the trail and in marginal snow conditions to keep the engine cool. The factory cooler is located directly under the fuel tank and has no cooling in the back of the tunnel. That may be great for weight distribution and packaging, but the cooling magic happens in the back of the tunnel. With the new taller/flexible lug tracks the snow does not carry very well forward into the tunnel. This is good for forward motion, but it's not great for cooling if the cooler is located only in the front of the tunnel. The cooling heat exchanger has always been integral to the chassis on Polaris models, but the new model bridges the entire top of the tunnel and created no path to add additional cooling passages to increase the cooler size. This is a compromise in the design as the water does not flow properl
