Product Details

The JE Pistons 217240 is a professional-grade forged piston set engineered from 2618 aluminum alloy for high-performance racing applications. This 8-piece set features a 23-degree dome design with a 4.000-inch bore, 1.250-inch compression distance, and 0.927-inch pin diameter. Designed to fit engines with 3.480-inch and 3.500-inch stroke configurations, these pistons deliver the strength and reliability demanded by serious engine builders.

Key Features:

  • Application-specific forgings with optimized, uniform crown thickness for maximum durability
  • Contact reduction groove minimizes frictional drag and improves efficiency
  • Accumulator groove increases top ring stability and sealing performance
  • CNC-machined side relief with lower support band for enhanced skirt strength
  • Honed pin bores with double pressure-fed pin oilers for superior lubrication
  • Wire locks included with each matched set

Each JE Pistons set is precision-matched to ensure balanced performance across all cylinders. For optimal results, use with recommended ring set J10008-4000-5. Backed by over 60 years of racing piston expertise, JE Pistons continues to set the standard for Chevy, Ford, Mopar, and Buick performance engines.
