Pistons and Piston Rings

Compressing the air/fuel mixture and dealing with the explosive forces inside an engine’s cylinders isn’t a job for weak parts. That’s why Chevrolet Performance pistons are premium quality and factory-tested to withstand the rigors of high-performance street and competition engines. Chevrolet Performance pistons are available in a variety of compression ratios and bore sizes. They’re sold individually, unless otherwise specified, and wrist pins are included.
