What material are these Mahle pistons made from?

These Mahle MS pistons are forged from 2618 aluminum. This alloy is chosen for its high strength and durability, making it well-suited for demanding high-performance engine applications.

What is the compression ratio achieved with these pistons?

With a 9.2cc dish volume and the specified bore and stroke, these pistons are designed to achieve a 13.3:1 compression ratio. This is suitable for high-performance naturally aspirated or boosted builds.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for the Chevrolet LSX 404 cubic inch (6.8L) engine. While they share characteristics with other LS engines, the specific bore, stroke, and compression height are tailored for this application. Always confirm fitment for your exact engine build.

Product Details

If you're building a high-performance Chevrolet LS engine, this Mahle MS forged piston set is designed for serious power. These pistons are specifically made for the 6.8L (404 cubic inch) LSX platform, featuring a 4.010-inch bore and a 4.000-inch stroke. The 1.110-inch compression height and 9.2cc dish volume contribute to a robust 13.3:1 compression ratio, ideal for naturally aspirated or forced induction applications where maximum power is the goal.

Mahle uses 2618 aluminum for these pistons, a strong and well-known material for high-performance forged pistons. This alloy offers excellent strength and durability under extreme cylinder pressures and temperatures. Each piston weighs in at 457 grams, helping to keep rotating assembly weight manageable while maintaining the necessary strength. The 0.927-inch pin diameter is standard for many performance LS builds, and the 6.125-inch rod length is also a common pairing. This set includes all eight pistons needed for a complete engine rebuild.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for significant horsepower gains and a reliable foundation for their LS engine, this Mahle piston set offers a well-built solution.
