Product Details

JE Pistons 181965 is a high-performance forged piston set engineered from 2618 aluminum alloy for serious racing and high-boost applications. This 8-piston set features an 18-degree dome design with a 4.030-inch bore, 1.250-inch compression distance, and 0.927-inch pin diameter. Designed to fit 3.480-inch and 3.500-inch stroke crankshafts, these pistons are ideal for small block Chevy and similar performance builds.

Key Features:

  • Application-specific forgings provide optimized, uniform crown thickness for strength and reliability
  • Contact reduction groove minimizes frictional drag for increased horsepower
  • Accumulator groove enhances top ring stability and sealing performance
  • CNC-machined side relief with lower support band adds skirt strength and durability
  • Honed pin bores ensure precise fit and reduced wear
  • Includes double pressure-fed pin oilers and wire locks for complete installation

JE Pistons are sold as precision-matched sets to ensure balanced performance. Recommended ring set: J10008-4030-5. Backed by over 60 years of racing piston expertise, JE Pistons delivers championship-proven quality for Chevy, Ford, Mopar, and Buick performance engines.

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

Autoplicity beat every other price online! Easy ordering process!!

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Found what I needed at an unbeatable price, easy purchase! No issues

The correct product that I ordered, and easy to find through there web site.thanks
