There is a Difference

While you may save a little money upfront by purchasing non-genuine parts, it could cost you a lot more in the long run.  To prove this, Cummins engineers performed thorough analytical testing pitting Genuine Cummins parts against their non-genuine counterparts.

Testing included visual inspection, critical measurements, materials analysis and parts chemistry analysis.  The following results demonstrate why Genuine Cummins parts are always better for your Cummins engine than non-genuine parts.

The Genuine Cummins Parts Advantage

Not All Parts are Created Equally

Often, what you can't see makes all the difference. Engine components must be accurate to specifications that can't be discerned by the human eye. Precision design, state-of-the-art manufacturing and rigorous testing ensures that Genuine Cummins parts perform at Cummins factory-specified levels of efficiency, reliability and durability. Check out our latest study on Genuine DPFs vs. "will-fit" DPFs.

Better Parts, Better Availability

In some instances, you can even choose from Genuine Cummins ReCon® parts as a lower-cost alternative.
