Product Details

Mahle is well-known for making original equipment (OE) quality engine components, and this piston and ring set for Cummins B engines is no exception. If you're rebuilding the engine in a Cummins B series with the PCR engine option, this set is built to the same standards as the parts that originally came in your truck. These pistons are designed with compensated ring grooves, which help ensure the rings are properly loaded and maintain good oil control. They also feature expansion-controlled designs, meaning they have tight fitting clearances. This helps reduce engine noise, wear, and emissions, while also improving how well the engine controls oil.

What's really convenient about this set is that Mahle includes everything you need to get started right in the box. The piston rings come already mounted on the pistons, and the necessary pins and clips are also included. This saves you a step during the engine build process and ensures you have all the correct pieces ready for installation. This set is for standard bore (STD) applications and includes six pistons, making it a complete package for your Cummins B PCR engine rebuild.
