Mahle MS GM 6.6L L5P 4.075in Bore 3.898in Stk 6.417in Rod -41.2cc 15.9 CR w/Thermal Barrier Set of 8

If you're rebuilding the heart of your GM 6.6L Duramax L5P engine, Mahle's MS Piston Set is a solid choice for performance and durability. These pistons are built to handle the demands of a rebuilt diesel engine, offering a significant upgrade over stock components. They are designed with a 4.075-inch bore and a 3.898-inch stroke, working in harmony with a 6.417-inch rod to optimize your engine's performance.

Mahle has engineered these pistons with a -41.2cc dish volume, contributing to a 15.9:1 compression ratio, which is crucial for efficient diesel combustion. A notable feature is the thermal barrier coating applied to the piston crown. This advanced coating helps to reflect heat away from the combustion chamber, reducing temperatures and protecting the piston from extreme heat stress, which is especially important in high-performance diesel applications. Each piston weighs in at 942g, a well-built component designed for longevity.

This set includes eight pistons, ensuring you have everything needed for a complete engine rebuild. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
