Doing a track extension on a 12 600 144 to a 155 stock polaris track. Then I got to thinking why not throw a 156 X 3'' on if it will fit for better performance. Does anyone know if there is enough clearance in this tunnel for it to fit? It has the same bulkhead and tunnel as the 144 assault so not sure if it will work. I am going to 660 it next year so thinking might as well put the bigger track on if I can now even though it may lose some track speed this year. Thanks in advance.
