What is the compression ratio achieved with these pistons?

These Mahle MS pistons are designed to achieve a 9.7:1 compression ratio when used with a 4.125-inch stroke crankshaft and a 6.125-inch connecting rod.

What material are these pistons made from?

The pistons are forged from 2618 aluminum, a strong and heat-resistant alloy commonly used in high-performance engine components.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for 416 cubic inch LSX applications with a 4.005-inch bore. They are not a direct fit for all LS engine variants and require specific bore and stroke combinations.

Product Details

These Mahle MS pistons are forged from 2618 aluminum, a strong material chosen for its ability to handle high performance and heat without deforming. They're built for LSX engines displacing 416 cubic inches, with a 4.005-inch bore and a 4.125-inch stroke. The -20cc dish volume, combined with a 6.125-inch rod length and a 0.927-inch pin, helps achieve a 9.7:1 compression ratio, making them a solid choice for builds where you want a bit more power than stock but still need to run on pump gas.

Mahle is a well-known name in engine components, and this set reflects their focus on reliable performance. Each piston weighs in at 390 grams, which is a reasonable weight for a forged piston of this size and strength. The 4.005-inch bore is a common size for 416 stroker builds, often achieved by boring out a factory 6.0L block. The included 0.927-inch pins are standard for many performance LS applications, and the 6.125-inch rod length is also a popular choice for this displacement.

This set includes eight pistons, ready for your next engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your new engine.
