JE Pistons LS1 SBC 15 DEG FT Set of 8 Pistons

If you're rebuilding the heart of your 1997-2004 Chevrolet Corvette for serious performance, a set of JE Pistons is a solid choice. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them the high tensile strength needed for demanding applications where stock parts just won't cut it. JE Pistons brings over 75 years of experience to the table, engineering these specifically for the LS1 engine to give you the best blend of durability and performance.

What sets these apart is JE's proprietary Forged Side Relief (FSR) design. This advanced forging minimizes friction and power loss by reducing skirt width, and it also saves weight with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps control combustion gas pressure to keep your rings seated properly and maintain consistent power. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, leading to quieter operation and longer life. Every piston is machined 100% in the USA, ensuring you're getting a well-built component ready for the track or the street.

This set includes eight flat-top pistons, each with a 3.905-inch bore, a 1.050-inch compression distance, and a 0.927-inch pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, always refer to the manufacturer's installation instructions and recommended assembly procedures.
