Product Details

The JE Pistons 312125 is a premium forged piston set designed for high-performance engine builds. Constructed from 2618 aluminum alloy for superior strength and heat resistance, these dome pistons feature a 4.070-inch bore diameter, 1.065-inch compression distance, and 0.927-inch wrist pin bore. This complete set includes 8 pistons for V8 applications.

Key Features:

  • Asymmetrical FSR (Forged Side Relief) design for optimized strength and reduced friction
  • 2618 aluminum alloy construction for extreme durability and thermal stability
  • Precision CNC-machined for exact tolerances and consistent performance
  • Enlarged skirt on major thrust side for enhanced stability under load
  • Reduced skirt on minor thrust side minimizes friction and weight
  • Dome top design increases compression ratio for improved power output
  • 4.070-inch bore diameter with 1.065-inch compression distance
  • 0.927-inch wrist pin bore diameter

JE Pistons' advanced forging process and modern design methodology deliver a lightweight yet incredibly strong piston that excels in demanding racing and high-performance street applications. The asymmetrical FSR design represents the latest evolution in piston technology, balancing structural integrity with reduced reciprocating mass for improved engine response and longevity.
