What is the DLC coating on this piston pin?

DLC stands for diamond-like carbon. Mahle uses this advanced coating, which they sometimes refer to as 'monotherm,' to significantly reduce friction and wear. This helps improve the longevity of the piston pin and the surrounding engine components.

What does the tapered design mean for this piston pin?

The tapered design is a specific feature that helps manage how loads are distributed. This can be important for ensuring the pin handles the forces within the engine effectively and contributes to its overall durability.

Can this piston pin be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Mahle is well-known for making solid engine components, and this piston pin is no exception. It's designed for Cummins 5.9L 24V engines, a common setup for many trucks and heavy-duty applications. This pin is what connects your piston to the connecting rod, transferring the force from combustion to the crankshaft, so it needs to be strong and precise.

This particular pin features a DLC (diamond-like carbon) coating, often called 'monotherm' by Mahle. This advanced coating helps reduce friction and wear between the pin and the piston or rod, which can lead to a longer lifespan for your engine's rotating assembly. The tapered design is also notable, allowing for specific load distribution within the engine.

When you're rebuilding or repairing the bottom end of a Cummins 5.9L 24V, using a well-built piston pin like this Mahle unit is important for ensuring reliable performance and durability. Make sure to check manufacturer specifications for proper installation procedures and any associated hardware you might need.
