What is the benefit of the galvanic coating on the cylinder?

The galvanic coating on the aluminum cylinder helps improve its wear resistance. This means the cylinder should hold up better over time and under normal operating conditions.

Does this kit include everything needed for a cylinder and piston replacement?

Yes, this Athena kit is designed as a complete cylinder kit. It includes the aluminum cylinder with its coating and a forged piston with molybdenum coating, ready for installation.

Can this cylinder kit be used on a California-registered vehicle?

No, this part is not CARB approved and cannot be shipped to California. You should verify local emissions regulations before purchasing if you are in California.
