What material are these pistons made from and why is it important?

These pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and ability to withstand the high stresses and temperatures found in performance engines, contributing to overall durability and performance.

What is the significance of the cam and barrel skirt profiles?

The cam and barrel profiles on the piston skirts are designed to optimize the piston's movement within the cylinder. This design helps to generate substantial power while minimizing wear on the cylinder walls, promoting a longer engine life.

Are these pistons legal for sale in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.
