Our take on the Stealth 66 Master Cylinder Assembly

The Stealth 66 is a replacement brake master cylinder assembly for 2019-and-newer Arctic Cat and Yamaha snowmobiles, including ZR, XF, M, Riot, Blast, Viper, Sidewinder, SXVenom and Mountain Max models. It is built around an anodized aluminum body for longer bore life, with an aluminum-caged reservoir and a translucent reservoir for checking fluid level. Stealth calls it the lightest master cylinder in the industry, which matters on a sled where every gram up front affects steering effort. It is a direct replacement for Arctic Cat 3602-290 and 3602-293 and Yamaha 8MY-F583T-10-00, and the kit includes the assembly and a pair of crush washers.
