JE Pistons Small Block Chevy 400 4.155in Bore 10.80cc Dome - Single Piston - Left

Forged from 2618 aluminum, this JE Pistons single piston is built to handle the demands of a high-performance Small Block Chevy 400 engine. JE Pistons has been making forged racing pistons for over 75 years, and these are engineered and machined right here in the USA for durability and optimized performance.

This specific piston features a 4.155-inch bore and a 10.80cc dome, designed to work with your engine's specific setup. It also includes JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. Depending on the application, some pistons may also feature a skirt coating to further reduce friction and wear, and an accumulator groove to help reduce combustion gas pressure, improving ring seal for consistent power delivery.

This is a single piston, identified as the 'Left' piston in the part number. If you're rebuilding or upgrading your Small Block Chevy 400, this well-built piston is a solid option for performance and longevity.
