Product Details

Mahle is a well-known name in the automotive industry, particularly for their expertise in engine components. This piston set is built for Cummins B 5.9L L6 engines, specifically for a standard bore rebuild. If you're diving into a major engine overhaul on your Cummins, getting the right pistons is crucial for restoring performance and reliability. This kit is designed to meet the original equipment specifications, ensuring a proper fit and function.

This assembly set includes six pistons, each with the necessary piston cooling (PC) features and rings. They are sized for a standard bore, meaning they're intended for engines where the cylinder walls are still within their original diameter or have been machined back to standard size. Mahle uses durable materials and manufacturing processes to create pistons that can handle the demands of a diesel engine. This attention to detail helps ensure consistent performance and longevity after your engine is rebuilt. The inclusion of rings means you have a complete set ready for installation, simplifying the rebuild process.

When rebuilding a diesel engine like the Cummins B 5.9L, using parts that match the original specifications is important for achieving the best results. This Mahle OE set is a solid option for that purpose. Remember that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitting and assembly procedures.
