Mahle MS LS Piston 376ci 4.065in Bore 3.622 Stroke 6.098 Rod 0cc 10.7CR w/Thermal Barrier - Set of 8

If you're building or rebuilding a GM LS engine, specifically a 376 cubic inch application, Mahle's MS LS Piston Set is a solid choice for serious performance. These pistons are designed to handle the demands of a high-performance engine, offering a robust foundation for your build. They feature a 4.065-inch bore and are engineered to work with a 3.622-inch stroke and a 6.098-inch connecting rod, providing a 10.7:1 compression ratio with a 0cc piston dish volume. This specific setup is ideal for those looking to achieve a balance of power and drivability in their LS engine.

What sets these pistons apart is the inclusion of a thermal barrier coating on the crown. This advanced coating helps to reflect heat away from the combustion chamber, which can lead to improved engine efficiency and durability under load. The pistons themselves are constructed from 4032 aluminum alloy, a material known for its strength and resistance to expansion, making it well-suited for high-performance applications where tight tolerances are crucial. Each piston weighs in at approximately 498 grams, contributing to a well-balanced rotating assembly. The pin diameter is 0.943 inches, a common size for performance LS applications.

This set includes eight pistons, enough for a complete V8 engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a successful installation, always refer to the manufacturer's detailed specifications and recommended assembly procedures to ensure optimal performance and longevity of your engine build.
