Breather Valves Spacers

The spacers that set correct clearance and alignment for crankcase breather assemblies on Big Twin and Sportster engines, giving a proper seal and the airflow the breather needs to control oil mist and crankcase pressure. We stock S&S and MCS, covering Twin Cam, Evolution, and Milwaukee-Eight. Precision-machined to tight tolerances — small parts, but they prevent leaks and keep the breather working as designed during a service or build.
