Product Details

JE Pistons 207486 is a precision-engineered forged piston set manufactured from aerospace-grade 2618 aluminum alloy for superior strength and heat resistance in high-performance racing applications. This 8-piston set features a flat top design with a 4.187-inch bore diameter, 1.630-inch compression distance, and 1.156-inch wrist pin diameter.

Key Features:

  • Application-specific forgings engineered for optimized, uniform crown thickness to reduce weight while maintaining structural integrity
  • Contact reduction groove minimizes frictional drag for increased horsepower and efficiency
  • Accumulator groove increases top ring stability and sealing performance for improved compression
  • CNC-machined side relief with lower support band provides additional skirt strength and prevents skirt collapse
  • Precision-honed pin bores ensure proper pin fit and reduced wear
  • Double pressure-fed pin oilers deliver consistent lubrication to wrist pin
  • Wire locks included for secure wrist pin retention
  • JE ProSeal piston rings included with each set for optimal sealing performance

JE Pistons has been the industry leader in forged racing pistons for over 60 years, delivering proven performance for Chevy, Ford, Mopar, and Buick racing engines. All JE pistons are sold as precision-matched sets to ensure balanced rotating assembly and consistent combustion characteristics across all cylinders.

They have the best prices and fast shipping too.

awesome parts dept.

Great prices and FAST shipping!! Definitely will buy products here again!

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
