2618 Alloy: High strength. Will not shatter like hypereutectic or cast pistons.

Strong, strutted skirt is specially designed to run at as little as .003" clearance, with excellent skirt wear and minimal noise or rock.

Radiused valve pockets for detonation resistance and increased flow around valves.

Anti-detonation grooves help keep the top ring groove free of carbon.

Nitride steel 1.5mm top, 1.5mm napier 2nd, and nitride 3.0mm oil rings for better oil control and reduced friction for more horsepower.

Pressure groove for enhanced ring seal.

Heavy duty chrome moly pins and spirolox.

Brush domes require minimal deburring by the engine builder.

Wiseco ArmorGlide skirt coated for lower friction, reduced noise, and superior life.
