S&S Cylinders for Evolution Sportster

Stock 3-1/2” bore cylinders by S&S made as strong as the famous Sidewinder big bore cylinders. Can be used as stock replacement for Evolution models and feature additional fin surface for improved heat dissipation and rigid casting for more reliable gasket seal. Oil return passages are stock for simple installation. We strongly recommend these jugs for stroker engines.
