Here's a walk through of some of the differences between the geardown kits offered for the polaris axys chassis. I can't say for 100% but I believe they will each fit the new Mattyx RMK sleds as well. the footage was shot a few months back now and I have had the opportunity to run the TKI setup. All I have to say is that from customer service, to fit and finish, to performance- TKI is the brand to go with! Tom and the rest of the crew at TKI are some of the best in the business that I have had the pleasure of dealing with! I never had a single issue with my setup this year and it pulled hard! Check out TKI CNC to fully understand what I'm talking about!
