Cummins Frequently Asked Questions
Are these genuine Cummins OEM parts?
Yes—our Cummins parts are genuine OEM, built to factory specifications for proper fit and performance.
How do I confirm fitment for 5.9L vs. 6.7L?
Match the part number and verify your truck’s year/engine. When in doubt, include your VIN/engine serial in the order notes and we’ll double-check.
Do Cummins sensors and actuators require calibration?
Some components (e.g., VGT actuators) may require a learn/adaptation procedure or specific tools. Refer to service information for your application.
Can I mix Cummins OEM with aftermarket performance parts?
Yes. Many builds use Cummins OEM for reliability on core systems while adding performance upgrades for airflow and fueling.
What maintenance items should I prioritize with genuine Cummins?
Common wear items include sensors, gaskets/seals, cooling components, and fuel system hardware—all critical for uptime and emissions compliance.
Do you carry Cummins parts for industrial/commercial engines?
Yes. Contact our team with your engine model and ESN; we source many industrial and commercial Cummins components in addition to Dodge Ram fitments.
