Mahle MS LS Piston 377ci 4.070in Bore 3.622 Stroke 6.098 Rod 0cc 10.8CR w/Thermal Barrier - Set of 8

Mahle is a well-known name in engine components, especially for their focus on precision and performance. This set of eight Mahle MS LS pistons is built for GM LS engines displacing 377 cubic inches, offering a solid foundation for a serious engine build. They feature a 4.070-inch bore and are designed to work with a 3.622-inch stroke and a 6.098-inch connecting rod, resulting in a 10.8:1 compression ratio.

These pistons are forged from 4032 aluminum, a material chosen for its strength and durability under high stress. A notable feature is the thermal barrier coating (TBC) applied to the piston crown. This advanced coating helps to reflect heat away from the combustion chamber, which can lead to improved efficiency and reduced detonation risk. The pistons also have a 0cc combustion chamber volume, meaning they are designed to be relatively flat-topped, and they come with a 0.943-inch pin. Each piston weighs in at 501 grams, keeping rotating mass in check.

This set is intended for performance applications where precise engine building is key. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and compatibility with other engine components.
