Mahle MS Piston Set GM L92/LS3 377ci 4.070in Bore 3.622stk 6.125in Rod 0.927 Pin 2cc 10.8CR Set of 8

Built from 4032 aluminum alloy, these Mahle MS pistons are designed for high-performance GM L92 and LS3 engines displacing 377 cubic inches. The 4.070-inch bore size is a key measurement for achieving this displacement, working in conjunction with the 3.622-inch stroke and 6.125-inch connecting rod length. This combination is crucial for building a robust engine capable of handling increased power demands.

The 2.0cc valve relief volume is specifically engineered to work with the piston's 10.8:1 compression ratio, ensuring efficient combustion and power delivery without excessive detonation. Each piston weighs in at 496 grams, a carefully managed weight that contributes to the engine's overall balance and responsiveness. The 0.927-inch pin diameter is standard for many performance applications, offering a strong connection point for the connecting rod.

This set includes all eight pistons needed for a complete engine rebuild. Mahle is a well-known name in engine components, and these pistons reflect their commitment to well-built parts for serious engine builds. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper fitment and assembly procedures.
