These Mahle MS cast performance pistons are built with a 4.095-inch bore and a 3.898-inch stroke, designed specifically for GM 6.6L Duramax diesel engines. They feature a 17:1 compression ratio and a dish volume of -41.8cc, which is crucial for achieving optimal performance and power gains in modified or high-performance applications. Each piston weighs 896 grams, indicating a well-built component designed to handle the stresses of a powerful diesel engine.

Mahle has engineered these pistons with a 6.417-inch rod length compatibility and a 1.951-inch compression height, ensuring proper fitment and geometry within the engine. The 1.358-inch pin diameter is standard for many heavy-duty diesel applications. This set includes all eight pistons needed for a complete engine rebuild, making it a solid option for anyone looking to upgrade their Duramax's internal components for increased power and durability. The cast construction offers a good balance of strength and weight for performance builds.

When rebuilding your Duramax, consider that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or a trusted mechanic to ensure these pistons align with your specific build goals and to confirm all necessary supporting components are accounted for during your rebuild.
