Mahle MS Piston Set BBM 499ci 4.375in Bore 4.15in Stroke 6.76in Rod 0.990 Pin -8cc 11.4 CR Set of 8

What you get in this set are eight Mahle forged pistons, ready to be installed in your Chrysler Big Block engine. These pistons are specifically sized for a 499 cubic inch displacement, featuring a 4.375-inch bore and a 4.150-inch stroke. They come with a 6.760-inch rod length compatibility and a 0.990-inch pin diameter, designed to work with your chosen connecting rods. Each piston has a dish volume of -8.1cc, which helps achieve a compression ratio of 11.4:1 with the specified cylinder head volume. These are constructed from 4032 aluminum, a material known for its strength and durability in high-performance applications.

Mahle has engineered these pistons for serious engine builds. The 4032 aluminum alloy offers good thermal expansion properties, which means they can handle the heat and stress of a powerful engine without excessive expansion or seizing. This material choice contributes to a well-built piston that can last. The dish volume of -8.1cc is a key spec for tuning your engine's compression ratio, allowing you to dial in performance for your specific needs, whether it's for street use or more demanding track applications. The included 0.990-inch pin is a common size, making it easier to pair with a wide range of connecting rods.

When building a high-performance engine, the details matter. These Mahle pistons are a solid option for anyone looking to rebuild or upgrade their Chrysler Big Block. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's recommendations and the manufacturer's installation instructions for proper fitment and assembly procedures to ensure optimal performance and longevity.
