Description

Accumulator Groove, Smooth Crown Finish, Pin Fit, and Skirt Coat. Sport Compact, Import and European Pistons are engineered, forged and machined 100% in the USA

Features & benefits

  • Forged in the USA using 2618 aluminum, yielding tensile strength and minimal thermal expansion
  • Designed specifically for BMW S50B32 Engines. To provide optimized performance durability
  • 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
  • Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
  • Made 100% in the USA
  • 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.
  • Smooth Crown Finish: Deburs all areas around the valve pocket and dome area, to reduces stress risers and prevent hot spots.
  • 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
