Mahle MS Chevrolet LS 5.3L 325cid 3.780in Bore x 1.324CH 3.622 Stroke 3.9cc 11.5 CR - Pist Set of 8

What you get in this box is a complete set of eight Mahle MS forged pistons, ready to go into your Chevrolet LS 5.3L engine. These aren't just any pistons; they're designed as a direct replacement assembly for the LT 5.3L DI engine, meaning they're built to fit right in and handle the demands of a performance rebuild or upgrade. Mahle is a well-known name in engine components, and this set is crafted from 4032 aluminum, a material chosen for its strength and ability to handle higher temperatures and pressures compared to cast aluminum.

Each piston in this set measures 3.780 inches in bore diameter, with a 3.622-inch stroke and a 1.324-inch compression height. They feature a 3.9cc dish volume, which contributes to an 11.5:1 compression ratio when paired with the right cylinder heads. At 474 grams each, they offer a solid balance of strength and weight for performance applications. The 0.943-inch pin size is standard for many LS applications, making integration smoother. These forged pistons are a strong choice if you're looking to build a more robust engine that can handle increased power and stress.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're planning a rebuild or performance build on your 5.3L LS engine, this set from Mahle is a well-built option that brings a good level of performance and durability to your project.
