The Mahle MS Piston Set for GM LS engines is engineered for high-performance applications, specifically designed for 6.0L and 6.2L flat top configurations compatible with LS3 and L92 style rectangular port heads. Each piston features a 4.03-inch bore diameter, providing robust power and durability for your engine rebuild or upgrade. The set includes eight pistons, each with a 3.622-inch stroke, 6.125-inch connecting rod length, and a 0.927-inch wrist pin diameter. With a compression ratio of approximately 10.2:1, these pistons are optimized for performance and efficiency, making them a reliable choice for street or strip applications.
Constructed from high-quality 4032 aluminum alloy, the Mahle pistons are designed to withstand the rigors of high-performance engine operation. They feature a flat top design with a -4.3cc dish volume, helping to achieve the desired compression ratio and engine characteristics. The pistons are lightweight at approximately 441 grams each, contributing to reduced reciprocating mass and improved throttle response. Mahle's precision manufacturing ensures consistent quality and fit, making installation straightforward and reliable.
These pistons are not carb-approved and require acknowledgment of this status before use. They are classified under automotive parts and are suitable for professional engine builds. As a non-CARB compliant component, they are intended for off-road, racing, or other applications where emissions standards are not mandated. With a Prop 65 warning, users should handle these components with appropriate safety precautions. Designed for enthusiasts and professionals seeking durable, high-performance pistons, the Mahle MS set is an excellent choice for maximizing the efficiency and power output of GM LS engines.
