Keith Black Hypereutectic pistons are favored for their improved power and reduced scuffing. The unique design & manufacturing processes combine to produce a rigid piston, which will rock less in the bore improving ring seal. These T-5 heat treated pistons also offer reduced thermal expansion, which allows you to run tighter clearances and allows the piston rings to seal better and minimize blow-by.

- Fully machined crowns and valve reliefs
- Drilled oil drain backs
- Full floating wrist pins
- Triple wound spiral locks
- Reflective alloy allows 2% power increase
