Product Details
If you're rebuilding a Chevy Small Block 400 and need a strong, reliable piston, this single piston from JE Pistons is a solid option. JE Pistons has been making performance engine components for a long time, and these pistons are built in the USA using 2618 aluminum, which gives them the high tensile strength needed for demanding applications.
This particular piston has a 4.155-inch bore and an inverted dome/dish design with a -26.80cc volume. The Forged Side Relief (FSR) design helps minimize friction and power loss by reducing skirt width, and some applications may include a skirt coating to further cut down on friction and noise. An accumulator groove can also be present to help reduce combustion gas pressure, improving ring seal for consistent power delivery.
Keep in mind that this piston is not CARB approved and cannot be shipped to California. It's designed for performance builds where durability and optimized power are key.
