HYPEREUTECTIC PISTONS
Hypereutectic pistons with anti-friction skirt coating are ideal for street, bracket racers and oval track. They are highly resistant to scuffing and wear. By combining the hypereutectic alloy with the permanent mold process, the piston is strong, lightweight, and thermally-efficient. These pistons run tighter piston-to-wall clearances, improving ring seal and longevity. Use 1.5mm, 1.5mm, 3mm Ring Set.

FORGED FLAT TOP PISTONS
Made from 4032 aluminum alloy for quieter operation and reduced piston to wall clearance. Up to 20 % lighter than traditional forged pistons that eliminate harmful stress concentrations for superior strength. Specifically designed for naturally aspirated or moderate nitrous applications. Use 1.5mm, 1.5mm, 3mm Ring Set.
