Upgrade your high-performance engine with the JE Pistons Piston Kit, designed for superior durability and precise performance. Crafted from 2618-T6 forged aluminum, these pistons feature a construction that ensures better aligned grain flow and higher tensile strength, making them ideal for demanding applications. The forged build enhances durability and reliability, even under extreme conditions, providing confidence in your engine's longevity. The kit includes two pistons, premium ring packs, wrist pins, and wire locks, offering a comprehensive solution for rebuilds and upgrades. Made in the USA, JE Pistons is renowned for quality and precision engineering.
The pistons incorporate skirt coatings that reduce operating friction and wear, extending component life and improving efficiency. Offset pins minimize piston rock and reduce operating noise, contributing to smoother engine operation. Notches on the skirt allow for optimal clearance at bottom dead center, preventing piston contact and ensuring proper movement within the cylinder. An accumulator groove taps into combustion gases below the top ring, promoting a more consistent and positive ring seal, which enhances overall engine performance and power output.
Designed for a 4.260-inch bore and a 4.500-inch stroke, these pistons feature a compression ratio of 12.0:1, suitable for high-performance builds requiring elevated compression. The pistons are equipped with M8 hardware for secure installation and reliable operation. Whether you're building a race engine or upgrading your street performance, these JE Pistons provide the durability and precision necessary for optimal engine performance and longevity.
