Mahle MS Piston Set GM LS 383ci 3.905in Bore 4in Stroke 6.125in Rod .927 Pin -14cc 10 CR Set of 8

If you're building a high-performance GM LS engine, this Mahle MS Piston Set is a solid choice for your 383 cubic inch application. Mahle is a well-known name in engine components, and this set is designed to handle the demands of a performance build. These pistons are crafted from 2618 aluminum, a material chosen for its strength and ability to withstand high temperatures and pressures common in performance engines.

This set is engineered for a 3.905-inch bore and a 4-inch stroke, which combine to create the 383 cubic inch displacement. The pistons feature a -14cc dish volume, contributing to a 10.0:1 compression ratio when paired with the right cylinder heads and gasket combination. They also come with a 6.125-inch rod length compatibility and a standard .927-inch wrist pin diameter, making them a versatile option for many LS engine builds. Each piston weighs in at approximately 383 grams, which is a good balance for performance and reliability.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions and specifications to ensure proper fitment and assembly for your specific engine build. This set includes pistons for a complete 8-cylinder engine.
