These hypereutectic Speed Pros are perfect for stock to moderate performance rebuilds. Silicone aluminum alloy allows them to run with tighter clearances, less friction, and increased sealing. Higher strength compared to regular cast pistons. Duroshield coating on piston skirts delivers longer life and reduced friction.
