  • Manufactured from high-strength, T-5 heat-treated, 390 hypereutectic aluminum alloy
  • Allows a tighter fit and longer piston and ring life
  • 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
  • Each kit contains two pistons, pins, spiral-lock pin clips and Hastings moly rings
  • Replacement piston rings sold separately
  • KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instructions included with piston for correct piston clearance.
  • Due to the thermal conductivity and design of KB pistons, special attention is required to the top ring end gap. Please read instructions furnished with piston for correct ring installation.
