Mahle MS 01-16 6.6L Chevy Duramax Piston & Ring Kit - 4.055in. Bore/3.898in. Stroke-Set of 8

Mahle is a well-known name in engine components, often supplying parts for original equipment manufacturers. This piston and ring kit is built for the GM 6.6L Duramax engine, specifically for those looking to rebuild or enhance their engine's performance. If you're working on a 403 cubic inch Duramax, this set is designed to fit your needs.

This kit features forged pistons, which are stronger and more durable than cast pistons, making them a solid choice for performance applications or heavy-duty use. The pistons have a 4.055-inch bore and a 3.898-inch stroke, with a compression height of 1.951 inches and a pin diameter of 1.358 inches. They are designed with a -40.7cc dish volume, contributing to a 16.6 compression ratio. The pistons also come with a Thermal Barrier Coating (TBC) on the crown, which helps to reduce heat transfer into the combustion chamber, potentially improving efficiency and durability. Each piston weighs 864 grams. This set includes pistons and rings for a complete engine build.

Please note that this piston set is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning. Ensure you check all manufacturer specifications and local regulations before installation.
