Mahle is a well-known name in engine components, often supplying parts for original equipment manufacturers. This expertise translates into their aftermarket performance parts, like this Mahle MS Piston Set designed for GM LS engines. If you're building a 370 cubic inch LS engine, these pistons are engineered to handle the demands of a performance build, offering a solid foundation for increased power and reliability.

This set features pistons with a 4.030-inch bore and a 3.622-inch stroke, designed to work with a 6.125-inch connecting rod and a 0.927-inch pin. They have a 12cc dish volume, which results in a 12.0:1 compression ratio when used with a typical LS head and gasket combination. The pistons themselves are forged from 2618 aluminum, a strong material known for its durability and resistance to expansion under high temperatures, making them suitable for boosted or high-compression naturally aspirated applications. Each piston weighs in at 477 grams, contributing to a well-balanced rotating assembly.

This piston set is sold as a complete set of 8, ensuring you have everything needed for a full engine build. Please 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.
