What is the purpose of the accumulator groove?

The accumulator groove, found on some applications, helps reduce pressure from combustion gases. This can prevent ring fluttering and improve ring seal, leading to more consistent power output from your engine.

What benefits does the skirt coating offer?

The skirt coating, when applied, reduces friction and wear on the piston skirts and cylinder walls. This not only helps prolong the life of the components but also contributes to reducing operating noise from the engine.

Are these pistons suitable for street use or only racing?

These pistons are forged from 2618 aluminum and feature designs like FSR to optimize performance and durability for high-demand applications. While they can be used in street performance builds, their construction is geared towards handling significant stress.

Product Details

Forged from 2618 aluminum, these JE Pistons are built for serious performance in your 350 SBC engine. This set includes eight pistons, each featuring a .450 dome and designed for a 4.020-inch bore. The 2618 aluminum alloy provides the high tensile strength necessary for demanding applications, ensuring these pistons can handle the stress of high-performance builds.

JE Pistons brings over 75 years of experience to the table, and these pistons reflect that expertise. They incorporate a proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

Every aspect of these pistons, from forging to machining, is done in the USA. This ensures a high level of quality control and supports domestic manufacturing. They are specifically designed for the 350 SBC engine and its typical use cases, optimizing both performance and durability. While these pistons are designed for high-demand performance, please note they are not CARB approved and cannot be shipped to California.
