Mahle MS LS Piston Set 377ci 4.070in Bore 3.622 Stroke 6.098 Rod 0.943 Pin 0cc 10.8CR - Set of 8

Built from 4032 aluminum alloy, this Mahle MS LS piston set is designed for high-performance GM LS engines displacing 377 cubic inches. The pistons feature a 4.070-inch bore and a 3.622-inch stroke, working with a 6.098-inch connecting rod to achieve a 10.8:1 compression ratio with a 0cc piston dish. This specific alloy is chosen for its strength and thermal expansion properties, making it well-suited for demanding applications where reliability and performance are critical.

Each piston weighs 501 grams, contributing to a balanced rotating assembly. The 0.943-inch wrist pin diameter is a common size for many performance LS applications, ensuring good compatibility with aftermarket connecting rods. Mahle's expertise in piston manufacturing means these are well-made components intended to handle the stresses of performance builds, whether for street or track use. This set includes all eight pistons needed for a complete engine rebuild.

Please note that this piston set is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning. Ensure you consult with your engine builder or refer to Mahle's technical documentation for specific installation requirements and compatibility with other engine components.
