Keith Black hypereutectic piston and ring kits include pistons made from 390 alloy and heat-treated to T6 standards, making them 30 percent stronger than ordinary untreated hypereutectics. Their 100 percent CNC-machined crowns, high upper compression-ring location, gas-accumulator groove, drilled oil returns, and spiral-lock retainer grooves make these pistons outstanding for performance applications. On top of that, they have a lightweight, rigid-rib skirt design that stabilizes the piston in the bore. To complete the install, the Keith Black hypereutectic piston and ring kits feature OE-quality piston rings manufactured from ductile iron, and the compression rings have moly facings for extra durability. They'll seal mild to high-compression engines, help to protect against oil blowby, and feature standard ring end gaps for an easy installation.
