This Mahle MS Piston Set is built for Chevy LS engines displacing 418 cubic inches. You get a complete set of forged pistons designed for a 4.080-inch bore and a 4.000-inch stroke, paired with 6.125-inch connecting rods and a .927-inch heavy-duty pin. These pistons feature a -5.8cc dish volume, resulting in an 11.2:1 compression ratio with a 4.000-inch stroke and a 4.080-inch bore. Each piston weighs in at 432 grams and is constructed from 4032 aluminum alloy.

Mahle is well-known for its engine components, and this piston set is no exception. The 4032 aluminum alloy is a strong choice for performance applications, offering good thermal expansion properties that help maintain piston-to-wall clearance as temperatures rise. This is crucial for preventing piston slap and ensuring consistent performance under demanding conditions. The included heavy-duty .927-inch pins are built to handle increased stress, making this set a solid option for rebuilt or performance-oriented LS engines.

When rebuilding your LS engine, selecting the right pistons is key to achieving your desired performance goals. This Mahle set is engineered for specific displacement and compression targets, so be sure it aligns with your build plans. Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to manufacturer installation guidelines for proper fitment and assembly procedures.
