JE Pistons SBC INV DOME -28CC Set of 8 Pistons

When you're building a high-performance small-block Chevy engine, the pistons are a critical component. This set from JE Pistons includes eight individual pistons, each forged from 2618 aluminum. This material is chosen for its high tensile strength, which is essential for handling the demands of performance applications. These pistons are designed with an inverted dome shape, creating a -28cc volume, and feature a 4.165-inch bore size. They also come with a 0.927-inch pin diameter and a 1.125-inch compression distance.

JE Pistons brings over 75 years of experience to their forged racing pistons, and these are no exception. They are engineered, forged, and machined entirely in the USA, ensuring a high level of manufacturing control. A notable feature is the proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, saving weight in the process. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set is designed specifically for each engine and use application, aiming for optimized performance and durability. It's important to note that these pistons are not CARB approved and cannot be shipped to California. They are intended for use in high-demand performance engines where durability and consistent power delivery are paramount.
