Product Details

JE Pistons 213111 is a high-performance forged piston set engineered from 2618 aluminum alloy for maximum strength and durability in demanding racing applications. This 8-cylinder dome piston set features a 4.145-inch bore diameter, 1.062-inch compression distance, and 0.927-inch pin diameter, designed for builders seeking optimal performance in Chevy, Ford, Mopar, and Buick racing engines.

Key Features:

  • Application-specific forgings ensure optimized, uniform crown thickness for consistent heat distribution and reliability
  • Contact reduction groove minimizes frictional drag for improved efficiency and power output
  • Accumulator groove increases top ring stability and sealing for better combustion control
  • CNC-machined side relief with lower support band provides additional skirt strength and reduced weight
  • Honed pin bores deliver precise pin fit and reduced friction
  • Double pressure-fed pin oilers ensure proper lubrication under extreme conditions
  • Wire locks included for secure piston pin retention
  • JE ProSeal piston rings included with each set for complete installation readiness

With over 60 years of racing piston manufacturing experience, JE Pistons delivers industry-leading quality and precision. Each set is carefully matched to ensure balanced rotating assemblies for smooth operation and maximum engine longevity. The 2618 alloy construction provides superior strength at elevated temperatures, making these pistons ideal for forced induction, nitrous oxide, and high-RPM naturally aspirated applications.

Love the pay with Amazon feature. Unbelievably fast shipping, great pricing on product. Excellent communication through the process. I'll be back!

Great price and fast shipping!

Best price I could find! Great customer service kept me informed through the whole order process to insure acuracy since it was being sent directly from the manufacture. Recieved my order in good time, right parts and no damage. Overall very satisfied and will be doing business again in the future.

Very competitive low prices and great product selection. Will definitely look to this vendor when purchasing automotive parts in the future.

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.
