The JE Pistons Piston Kit (Part Number 398756) is engineered for high-performance automotive applications, providing superior durability and precise performance. Crafted from 2618-T6 forged aluminum, these pistons feature an optimized grain flow for enhanced strength and reliability under demanding conditions. The forged construction ensures better resistance to thermal expansion and mechanical stress, making them suitable for both street and racing engines. This kit includes two pistons, premium ring packs, wrist pins, and wire locks, offering a comprehensive upgrade for your engine rebuild or performance enhancement.
Designed with performance in mind, the JE Pistons feature a skirt coating that reduces operating friction and minimizes wear over time, contributing to longer engine life. Offset pins are incorporated to reduce piston rock, which helps decrease operating noise and improve overall engine smoothness. The piston skirts are equipped with notches that provide optimal clearance at bottom dead center, preventing piston-to-valve contact and ensuring reliable operation. Additionally, the accumulator groove taps into combustion gases below the top ring, promoting a more consistent, positive ring seal for improved compression and power output.
Manufactured in the USA, JE Pistons are a trusted choice for enthusiasts seeking high-quality components that deliver consistent performance and durability. Whether you are building a high-performance street engine or a race-ready powertrain, this piston kit offers the features necessary to maximize engine efficiency and longevity.

Features:

  • Forged 2618-T6 aluminum construction for enhanced strength and durability
  • Skirt coating reduces friction and wear for longer engine life
  • Offset pins minimize piston rock and reduce noise during operation
  • Notches at the bottom of the piston skirt provide optimal clearance at bottom dead center
  • Accumulator groove improves ring seal and promotes consistent compression
