3. OEM Part: By purchasing an original equipment manufacturer (OEM) flywheel, you can ensure a perfect fit and compatibility with your engine.

1. Cost: OEM parts, such as the Cummins 206398 flywheel, tend to be more expensive than aftermarket alternatives.

In conclusion, purchasing a Cummins 206398 flywheel offers the benefits of durability, improved engine operation, and OEM fitment. However, it comes with a higher cost, potential availability issues, and longer delivery times compared to aftermarket alternatives.

If you value the peace of mind that comes with using genuine parts and are willing to pay a premium, then a Cummins 206398 flywheel might be the best choice for you.
