Sentinel Hayes Brake Snowmobile Mount Kit - #34454. This mount kit only works with the Sentinel hand guards! Only 1/2" of space is needed near your handlebar grips to accommodate the mounting brackets. Unique design allows you to fit the brake side mounting bracket in place of your existing top clamp. All parts are aluminum for lightweight strength and durability. For snowmobiles with large control clusters, look at using Tri-Mount Kit - 34269 which mounts past the bend in the handlebars. Fits: Arctic Cat '12-'16; Polaris Axis '15-'16; Yamaha SR Viper '13-'16.
