Keith Black Hypereutectic Piston Kit For Harley Shovel Head

Keith Black Pistons are crafted from high-strength 390 hypereutectic T5 aluminum alloy for superior strength and a tighter fit!

Features:

  • High-strength, T-5, heat-treated, 390 hypereutectic aluminum alloy
  • Diamond-machined pistons are held to plus or minus one gram weight and less than one-half-thousandth-inch (.0005") tolerances from piston to piston
  • KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal
  • Each kit contains two pistons, pins, spiral-lock pin clips and Hastings moly rings

Specs:

  • 3.498" stock size
  • 8.3:1 compression ratio
