Add Strength and Power to Your Pistons
Sealed Power Hypereutectic Pistons are built to exacting tolerances and feature an aluminum casting with an anti-friction skirt coating that is highly resistant to scuffing and wear. The Duroshield skirt helps improve fuel economy, doesn't require any additional clearance, extends piston life, and increases horsepower with less friction. These durable pistons operate with tight bore clearances and work perfectly with normal-range ring end gaps, making them great for street, bracket racing, and oval track applications.
