Breather valves that regulate crankcase pressure on Big Twin and Sportster engines, keeping oil leaks down and the motor breathing efficiently. We stock S&S, MCS, and Jims, covering Twin Cam, Milwaukee-Eight, Evolution, and Shovelhead. You'll find OE-spec replacements as well as high-performance valves that improve oil separation. Keeping the crankcase ventilation right protects your gaskets, seals, and overall engine life — cheap insurance on an air-cooled V-twin.
