What does '.020 Oversize' mean for these pistons?

'.020 Oversize' indicates that these pistons are manufactured to be 0.020 inches larger in diameter than the original factory pistons. This size is used when the engine's cylinder bores have been machined (honed or bored) to match this larger diameter during an engine rebuild.

What is included in this piston set?

This set includes six pistons, which is the complete number needed for a standard inline-six Cummins 6.7L B Series engine. It does not include piston rings, wrist pins, or connecting rods, which are typically purchased separately.

Can these pistons be shipped to California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Mahle OE offers this set of six .020 inch oversize pistons specifically for Cummins 6.7L B Series diesel engines. When rebuilding or repairing your engine, using pistons that are the correct size is critical for proper sealing and performance. These pistons are manufactured to meet the original equipment specifications for your Cummins engine, ensuring a direct fit and reliable operation.

Mahle OE is known for its well-built engine components, and this piston set is no exception. Each piston is crafted from durable materials designed to withstand the high pressures and temperatures typical of diesel operation. The .020 inch oversize dimension means these pistons are slightly larger than stock, which is necessary when the cylinder bores have been machined to match this size during an engine rebuild. This precise sizing is key to achieving optimal compression and preventing blow-by, contributing to the overall health and longevity of your engine.

This set includes all six pistons needed for a complete engine overhaul. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual or consult with a qualified mechanic for specific installation procedures and torque specifications when working on your engine.
