About this part

Product Details

Mahle is well-known for its high-performance engine components, and this MS Piston Set for GM LSX engines is no exception. If you're building a powerful 393 cubic inch LSX engine, these pistons are designed to handle the demands of a performance build. They are engineered to work with a 4.155-inch bore and a 3.622-inch stroke, fitting a 6.125-inch connecting rod with a 0.927-inch pin.

This set features flat-top pistons with a -5.8cc dish, contributing to a 10.5:1 compression ratio when paired with the correct cylinder heads and gasket combination. The pistons themselves weigh in at 491 grams, a consideration for engine balancing. They are constructed from 2618 aluminum, a strong and lightweight material commonly used in high-performance pistons for its durability under high temperatures and pressures. This material choice helps ensure reliability in demanding applications.

This set includes pistons for a complete 8-cylinder engine. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or a trusted mechanic to ensure these pistons are the right fit for your specific build and to discuss any necessary supporting components for optimal performance and longevity.
