Howards Cams Inverted Dome Pro Max 2618 Forged Race Pistons Chevrolet Big Block V8 Mark IV - 856027123-1

Howards Cams Inverted Dome Pro Max 2618 Forged Race Pistons

Looking to boost your Chevrolet Big Block V8 Mark IV’s performance? The Howards Cams Inverted Dome Pro Max 2618 Forged Race Pistons are crafted to deliver exceptional strength and reliability on the racetrack. These pistons are designed for serious racers who demand nothing but the best from their engines.

Performance-Driven Design

The secret to the Pro Max pistons lies in their forging process. Made from high-quality 2618-T61 billet aluminum, these pistons are not just any ordinary components. They undergo heat treatment and aging, resulting in a robust design that withstands extreme stress. Unlike standard pistons, which may contain up to 1% silicon, the Pro Max pistons feature minimal silicon content, ensuring they maintain their shape under high RPMs and pressure.
