These Keith Black hypereutectic piston and ring kits include pistons made from 390 alloy and heat-treated to T6 standards, which makes 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.

Ring Placement

Summit RacingSummit Racing Verified Purchase

Lowering the bottom two ring grooves relative to the pin, reduces the available piston support area for pressed in rod pins. 636 to 638 gms.
