Product Details

The JE Pistons 182032 is a high-performance forged piston set engineered from 2618 aluminum alloy for demanding racing and high-horsepower applications. This 8-piston set features a 23-degree dome design with a 4.165-inch bore diameter, 1.000-inch compression distance, and 0.927-inch pin diameter, making it ideal for custom engine builds requiring precise specifications and maximum durability.

Key Features:

  • Application-specific forgings provide optimized, uniform crown thickness for improved heat distribution
  • Contact reduction groove minimizes frictional drag and parasitic power loss
  • Accumulator groove increases top ring stability and sealing performance
  • CNC-machined side relief with lower support band adds critical skirt strength
  • Honed pin bores ensure precise pin fit and reduced wear
  • Double pressure-fed pin oilers provide enhanced lubrication to wrist pins
  • Wire locks included for secure pin retention
  • Oil rail support included for proper ring support

JE Pistons has led the forged racing piston industry for over 60 years, delivering proven performance for Chevy, Ford, Mopar, and Buick engine platforms. Each piston set is carefully matched for consistent weight and dimensions. Recommended ring set: J10008-4165-5.

Great price and quick communication. Can't beat them.

All seems great. Had item in stock as on there website and it was shipped quickly.

awesome product came in fast and very pleased with the website keep up the good work guys! thanks! high recommended.!<br>

Ordered my car accessory on 8/2, shipped on 8/3 and will be delivered on 8/4. Best prices online, great service, product in stock, and fast delivery. Nice Job & Kudos to Autoplicity!

Grea price: better than recreation or outdoor chains' sale price. Snafu with shipping, paid for 2-day but got std. Cust service happily refunded the shipping charge so I'm happy.

I shopped around a little first and Autoplicity had the best price on a wideband sensor and gauge. When I needed a fuel pressure regulator too, I found their price was the best so I ordered both from them. Great prices and fast deliver!
