The Vertex 23391B is a forged replica piston kit designed for enhanced performance. It features a 13.5:1 compression ratio and is constructed from durable 2618 aluminum. The piston skirt is coated with Molybdenum Disulphide for faster break-in and increased longevity.

This kit includes the piston, rings, wrist pin, and circlips, making it a comprehensive replacement or upgrade for your engine. All Vertex pistons undergo a T-5 hardening and tempering cycle for added strength.
