What is the main benefit of the molybdenum coating on the piston?

The molybdenum coating on the forged piston helps to reduce friction and improve wear resistance. This means the piston should last longer under normal operating conditions.

Does this kit come with everything needed to replace the cylinder?

This kit includes the aluminum cylinder with a galvanic coating and a forged piston with a molybdenum coating. You will need to source other necessary gaskets and seals separately for installation.

Can this cylinder kit be shipped to California?

No, this product is not CARB approved and cannot be shipped to California due to emissions regulations.
