What is the primary benefit of a forged piston over a cast piston?

Forged pistons are made by shaping aluminum under extreme pressure, which creates a denser, stronger grain structure. This makes them more resistant to deformation and failure under high heat and pressure compared to cast pistons.

Can I buy a complete set of these pistons?

This product listing is for a single piston. You will need to order the correct quantity of pistons for your specific engine build, typically one for each cylinder.

Are there any restrictions on shipping this piston?

Yes, this piston is not CARB approved and cannot be shipped to California due to emissions regulations.
