Mahle MS Chevrolet LS 5.3L 329cid 3.800in Bore x 1.324CH 3.622 Stroke 3.9cc 11.6 CR - Pist Set of 8

This product is a set of eight Mahle MS forged pistons designed for Chevrolet LS 5.3L (329 cubic inch) engines. You get the pistons themselves, ready to be installed as part of an engine rebuild or performance upgrade. These are drop-in replacement assemblies, meaning they are built to fit within the stock dimensions of your LS engine, simplifying the installation process compared to custom-machined components.

Mahle crafted these pistons from 4032 aluminum, a material known for its strength and thermal expansion properties, making it well-suited for high-performance applications. Each piston features a 3.800-inch bore and a 3.622-inch stroke, with a compression height (CH) of 1.324 inches. The dish volume is 3.9cc, contributing to an 11.6:1 compression ratio when paired with the correct cylinder heads and gasket combination. Weighing in at 482 grams each, these pistons are designed to handle the demands of a rebuilt or modified LS engine, offering a solid foundation for improved performance.

It's important to note that 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, especially when dealing with critical engine components like pistons. Ensure all related engine parts are within specification before installation to achieve optimal results.
