What is the main 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 stress compared to cast pistons.

Does this piston come with rings, pins, and clips?

This part number is for the piston only. Rings, wrist pins, and clips are typically sold separately and should be sourced to match the piston specifications.

Can this piston be shipped to California?

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