Introducing the Mountaintech Crossover A Arm Kit! Developed in response to customer demand, this kit has the same design features as the Mtn and Trail kit but comes in at 41" wide and 2" forward. Designed specifically to retain trail performance and at the same time offer better off trail manners. 41" wide for trail riding but kicking the spindles forward 2" really helps off trail manners because it makes the sled behave as if it has a narrower front end. This kit has been on the snow for almost a year now, but is now officially available.
