About this part

Product Details

Mahle is a well-known name in engine components, particularly for their piston designs. This Mahle MS Piston Set is built for GM LSX engines displacing 428 cubic inches, offering a solid foundation for a performance build. If you're looking to rebuild the heart of your LS-based vehicle, these pistons are a key component to consider for improved power and efficiency.

These pistons are forged from 2618 aluminum, a strong material chosen for its durability under high stress, which is crucial for performance applications. They feature a 4.065-inch bore and are designed to work with a 4.125-inch stroke and a 6.125-inch connecting rod, using a .927-inch wrist pin. The dish volume is -5.8cc, resulting in a compression ratio of 11.4:1 when paired with the right cylinder heads. Each piston weighs 427 grams, contributing to a balanced rotating assembly. This set includes eight pistons, enough for a complete V8 engine.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, ensure proper installation according to Mahle's guidelines, which typically involves precise machining and assembly techniques for high-performance engines.
