In this set, you get six Mahle OE pistons specifically made for Cummins B 5.9L engines. These are 0.020 inch undersize pistons, designed for a 17.1:1 compression ratio, and are compatible with engines using the 'C' VIN code and the ETH designation. If you're rebuilding the engine in your Cummins B 5.9L, especially if you're looking to restore or enhance its original performance, these pistons are a solid choice from a well-known name in engine components.

Mahle OE is known for making parts that meet or exceed original equipment specifications, and these pistons are no different. They are built to handle the demands of a diesel engine, ensuring reliable performance and durability. The 0.020 inch undersize means they are intended for engine blocks that have been bored out to match this specific measurement during a rebuild. This precise sizing is crucial for proper piston-to-wall clearance, which affects oil consumption, blow-by, and overall engine longevity. The 17.1:1 compression ratio is a key specification for these engines, impacting power delivery and efficiency.

When undertaking an engine rebuild, it's important to ensure all components work together. These pistons are designed to be a direct replacement for the original equipment, simplifying the installation process. Always refer to your engine's service manual for the correct installation procedures, including ring gap settings and proper lubrication. Please note that these pistons are not CARB approved and cannot be shipped to California.
