The Mahle MS Piston Set (Part Number: mhl930224510) is engineered specifically for GM LS engines with a 366 cubic inch displacement, offering precise compatibility with LS3 and L92 style rectangular port heads. Designed for high-performance applications, these pistons feature a 4.01-inch bore diameter and a 3.622-inch stroke, providing optimal fit and durability for demanding engine builds. The set includes eight pistons, each weighing approximately 7.3 ounces, made from high-quality 2618 aluminum alloy for excellent strength-to-weight ratio and thermal stability. The pistons are designed with a 0.927-inch pin, a compression height of 1.314 inches, and a combustion chamber volume of -12.1cc, ensuring proper piston-to-head clearance and compression ratio for enhanced engine efficiency. The Mahle pistons are not carb-approved and require acknowledgment of carburetor restrictions, making them suitable for specific racing or performance applications. These pistons are a critical component for builders seeking reliable, high-performance components, and are compatible with late-model LS variants. Constructed to meet strict manufacturing standards, they offer durability and consistent performance in high-stress environments. Whether upgrading an existing engine or building a new one from scratch, the Mahle MS Piston Set delivers precision, strength, and performance for your GM LS engine project.
