Product Details

JE Pistons 243314 is a premium forged racing piston set engineered from 2618 aluminum alloy for high-performance engine builds. This 8-piston set features a dome-style crown design with a 4.610-inch bore diameter, 1.060-inch compression distance, and 0.990-inch wrist pin diameter. Designed for serious racing applications, these pistons deliver exceptional strength and durability under extreme combustion pressures and temperatures.

Advanced Engineering Features:

  • Application-specific forgings provide optimized, uniform crown thickness for consistent heat dissipation
  • Contact reduction groove minimizes frictional drag between piston and cylinder wall
  • Accumulator groove design increases top ring stability and improves sealing performance
  • CNC-machined side relief with lower support band adds critical skirt strength
  • Precision-honed pin bores with double pressure-fed pin oilers ensure proper lubrication
  • Wire locks included for secure pin retention

Each set includes JE ProSeal piston rings specifically matched to these pistons. All JE Pistons sets are weight-matched for perfect balance and smooth operation. With over 60 years of forging expertise, JE Pistons remains the trusted choice for Chevy, Ford, Mopar, and Buick racing engine builds.

They have the best prices and fast shipping too.

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.

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.
