Description
Crankcase pressure management directly impacts engine reliability and performance—excessive blow-by reduces seal integrity and contaminates your oil. The S&S Cycle Breather Gear delivers superior scavenging efficiency with an elongated pocket design that maximizes suction, keeping your crankcase at optimal pressure during high-rpm operation. Whether you’re running stock displacement or a built motor, this upgrade prevents oil leakage, extends component life, and maintains consistent performance across the power band.
