What is the compression ratio with these pistons?

These pistons feature a -4.5cc dish and are designed to achieve an 11.6:1 compression ratio when used with compatible LT1, L86, or LT4 cylinder heads. Always verify with your head chamber volume for precise final compression.

What material are these pistons made from?

The Mahle MS pistons are forged from 2618 aluminum. This material is chosen for its high strength and ability to withstand the stresses of performance engine builds.

Are these pistons suitable for daily driving?

These pistons are designed for high-performance applications and are not CARB approved, meaning they cannot be shipped to California. While durable, their primary design is for enhanced power and stress handling in performance builds.
