Product Details

The JE Pistons 173586 forged piston set delivers race-proven performance for nitrous oxide applications in high-performance V8 engines. Constructed from premium 2618 aluminum alloy, these pistons feature a 23-degree solid dome design optimized for increased compression and power delivery. Each set includes 8 matched pistons precision-machined to a 4.155-inch bore diameter with a 1.125-inch compression distance and 0.927-inch pin bore.

Key Features:

  • Application-specific forgings with optimized, uniform crown thickness for strength and heat dissipation
  • Contact reduction groove minimizes frictional drag for improved efficiency
  • Accumulator groove increases top ring stability and sealing under extreme cylinder pressures
  • CNC-machined side relief with lower support band provides additional skirt strength
  • Honed pin bores ensure precise fitment and reduced wear
  • Double pressure-fed pin oilers deliver enhanced lubrication to critical areas
  • Oil rail support included for improved ring seal and stability
  • Wire locks included with each piston

Designed specifically for nitrous oxide applications, these pistons incorporate JE's 60+ years of racing experience and engineering excellence. The 2618 alloy composition offers superior strength and resistance to detonation compared to standard hypereutectic pistons, making them ideal for forced induction and power-adder setups. Recommended ring set: J10008-4155-5 (sold separately).
