LS-Series Pistons and Piston Rings

Premium-quality hypereutectic aluminum alloy pistons are used on most production LS engines (the LS9 supercharged and the CT525 use forged aluminum). They are lightweight, durable and promote quieter operation. Chevrolet Performance offers production and oversized pistons for many applications. They’re sold individually, unless otherwise specified. Check the accompanying chart for part numbers, specs, sizes and applications.
