What's in the Box

Keith Black Hyperutectic 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.

  • 390 Hypereutectic alloy
  • Fully machined crowns and valve reliefs
  • Drilled oil drain backs
  • Full floating wrist pins
  • Triple wound spiral locks
  • Reflective alloy allows 2% power increase
  • Quench dome technology minimizes deterioration
  • Zero deck quench designs
  • Lightweight wrist pins

For S/B Chevy 350 c.i. (4.000" bore x 3.48" stroke).
