DESCRIPTION

KB PISTONS Super Duty Piston

Engineered for durability and precision, the KB PISTONS Super Duty Piston delivers race-proven strength and quiet, reliable operation for high-performance and heavy-duty applications.

Key Features

  • Anodized top ring groove and crown for improved wear resistance and heat protection.
  • Line2Line abradable skirt coating applied to a total thickness of 0.003" for a ZERO initial fit — the coating hones in for a tight, quiet running clearance.
  • Round wire locks for secure ring retention under extreme conditions.
  • Premium Hastings ring package: 1.2mm / 1.2mm / 3.0mm Steel Nitride top ring with a Ductile Napier second ring for superior sealing and longevity.
  • Forced wrist pin oiling to ensure reliable lubrication and reduced wear at the pin bore.
  • M8 version specifics: flat top 1.2cc, compression height 1.083", and valve pockets sized to accommodate 1mm oversize valves.

Benefits

  • Enhanced thermal and wear protection for extended service life.
  • Noise reduction and improved running clearance right out of the box.
  • Optimized ring sealing and oil control for consistent performance.
  • Designed for high-stress environments and precision engine builds.

Choose the KB PISTONS Super Duty Piston for a balance of strength, precision, and race-ready reliability.
