Features & benefits

  • Designed specifically for Gen 5 LT1 and LT4 Engines. To provide optimized performance durability
  • Includes high-quality wrist pins, and locks
  • Made 100% in the USA
  • Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
  • Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
  • Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
  • Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
  • Designed specifically for each engine and use application to provide optimized performance durability
  • Accumulator Groove: A specialty groove between the top and second ring provides added volume for blow-by gases. This helps reduce pressure between the rings, improving top ring seal and minimizing ring flutter at high cylinder pressures.
  • Double Pin Oilers: Deliver twice the amount of oil to the wrist pin as compared to the standard single pin oiler.
  • Pin Fit: The pin bore is precision honed to attain an exact pin clearance. Clearances typically range from .0003 to .0010 between the wrist pin and pin bore.
  • Skirt Coat: Skirt Coat reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
