Description

JE Pistons offers 400 small block 23-degree dome top pistons for a wide range of applications, including many Chevy vehicles from 1967 and up. These single replacements are forged using 2618 aluminum, yielding high tensile strength needed for high-demand performance. The pistons are designed specifically for each engine.

Additional details:

* Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin
* Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
* Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power

As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its wide range of premium forged pistons for domestic applications. JE pistons are designed for each specific engine and racing application to provide the ultimate combination of durability and performance. From dirt track to drag strip, JE Pistons' performance is proven in victory lane time and time again.
