Brand new Wilwood snowmobile master cylinder. Universal fit the left side of any 7/8" handlebar. Features a 1/2" bore and 3/8-24 inverted brake line threads. Make sure your brake line fitting is the same thread or you may have to purchase an adapter from an auto parts store. Also has an injection molded handle with a three position parking brake. The beauty of this master cylinder is it has a split mounting clamp so you do not have to remove your grip to install it! Universal design so it will fit many Polaris, Arctic Cat, Ski-Doo and Yamaha snowmobiles with hydraulic brakes. *DOES NOT INCLUDE BRAKE LIGHT SWITCH
