What material are these pistons made from?

These Manley pistons are forged from domestic 2618 alloy. This material is chosen for its superior strength and performance characteristics, making it well-suited for demanding engine applications.

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

The cam and barrel profiles on the piston skirts are designed to manage piston movement within the cylinder bore. This helps to reduce noise and wear on the cylinder walls while still contributing to overall engine power.

Are these pistons compatible with all LS engines?

These pistons are designed for a specific bore size of 4.185 inches and a dish volume of -18.00cc. While they are for Chevrolet LS engines, you must verify that these specifications match your particular engine build and intended compression ratio.
