If you're building a high-performance GM LSX engine for serious power, a solid set of pistons is where you start. This Mahle MS Piston Set is designed for 408 cubic inch LSX applications, giving you the foundation for a potent powerplant. These pistons are crafted to handle the demands of performance builds, ensuring reliability when you push your engine hard.

Mahle uses 2618 aluminum for these pistons, a well-known material for its strength and durability under high temperatures and pressures. This set features a 4.030 inch bore and a 4.000 inch stroke, paired with a 6.125 inch rod and a .927 inch pin. The dish volume is -5.8cc, which, when combined with the specified components, results in a 11.6:1 compression ratio. This compression level is ideal for naturally aspirated or forced induction builds aiming for significant horsepower gains. Each piston weighs in at 423 grams, contributing to a balanced rotating assembly for smoother operation and reduced stress on your engine's internals.

This set includes eight pistons, all the hardware needed for installation, and is ready to be fitted into your LSX block. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures to ensure optimal performance and longevity of your new engine build.
