For over 100 years, Cummins has been the industry’s #1 choice for new diesel engines, as well as the parts used to keep them operating reliably and efficiently for decades. The Genuine Cummins parts that you buy from a Cummins distributor or authorized dealer are built to our exact standards, meeting or exceeding original specifications on your QSK engine.

Today non-genuine parts suppliers develop parts that they think will fit your Cummins engine. While the initial savings can be enticing, oftentimes there are differences compared to the Genuine Cummins part that you may or may not be able to see with the naked eye. Your genuine part will perform the same or better than the original.

With Cummins, you can get both your propulsion engines and your auxiliary power from a single, reliable source. Your crew can use one set of diagnostic tools on all your engines. Any and every type of maintenance or service question can be answered by calling Cummins Care, where our Cummins experts are available to lend assistance 24/7. It’s the complete package, one you can trust, whether you’re cruising the Greek islands or outrunning a tropical storm.
