If you're building a high-performance GM LSX engine and need a solid set of pistons for a 366 cubic inch displacement, this Mahle MS Piston Set is a strong contender. These pistons are designed for a 4.010 inch bore and feature a 1.304 inch compression height, working with a 3.622 inch stock stroke and a 6.125 inch rod. The 0.927 inch wrist pin diameter is standard for many performance LS applications.

Mahle uses 2618 forged aluminum for these pistons, a material known for its strength and durability under high stress, making it ideal for boosted or naturally aspirated performance builds. This set is engineered to achieve a 9.9:1 compression ratio with a -5.8cc valve relief volume, which is a popular target for many street and track performance LS engines. Each piston weighs in at 443 grams, contributing to a well-balanced rotating assembly. 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. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning to ensure optimal performance and longevity of your build.
