As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its range of Pro Series pistons. Pro Series® Piston kits feature purpose-built forging designs that reduce overall piston weight without sacrificing strength or durability. Internal and external strut braces significantly reduce stress on critical areas while ultra-flat ring grooves improve ring seal for better, sustained performance.

  • Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss
  • Engineered, forged and machined 100 percent in the USA
  • Je Pro Seal Rings Included
  • Low Friction Skirt
  • Hand Deburred
