What's in the Box

Info

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.

For Chevy 400 c.i. (4.125" bore x 3.75" stroke).

  • 390 Hypereutectic alloy

This piston which is Keith Black part number KB168 uses 5/64" top and second rings and 3/16" oil rings. Those rings would be part number 9152187-A. Keith Black also makes piston that use 1/16" top and second rings and 3/16" oil rings which would be part number 9152187-C. You will need to either verify the part number of your pistons or measure the ring width that they require.
