The JE Pistons Part Number 398727 piston kit is designed for high-performance engine builds, offering superior durability and precision. Crafted from 2618-T6 forged aluminum, these pistons feature a grain flow structure that ensures better alignment and increased tensile strength, making them ideal for demanding applications. The forged construction enhances overall durability, allowing the pistons to withstand the rigors of high-stress engine environments.
The piston design incorporates a skirt coating that reduces operating friction and wear, contributing to longer engine life and improved efficiency. Offset pins are included to minimize piston rock and reduce operating noise, resulting in smoother engine operation. Notches on the skirt provide optimal clearance at bottom dead center, preventing interference during piston movement. An accumulator groove atop the piston helps to tap into combustion gases below the top ring, promoting a more consistent seal and enhancing overall performance.
This kit includes two pistons, premium ring packs, wrist pins, and wire locks, offering everything needed for a complete installation. Made in the USA, the JE Pistons kit is engineered to meet rigorous quality standards and deliver reliable, high-performance results for racing or street applications.
