AN UNPARALLELED
ABILITY TO LOOK AHEAD.
Cummins customers can expect a digitally enriched experience over the life of their vehicles. Newly released features connect in-mission operations directly to maintenance and repair processes, giving customers an unparalleled ability to look ahead, optimize operations and minimize downtime.
ENGINE MAINTENANCE INTERVALS
ALL ABOUT UPTIME.
To improve uptime, we extended the recommended engine maintenance intervals so you can go longer between oil drains and fuel filter changes. A completely maintenance-free breather means you’ll never have to change a crankcase ventilation filter again. Trucks go longer between trips to the garage for scheduled maintenance and more money goes back to your bottom line. New for 2024, the L9 offers advancements in connectivity to help you identify, prevent and resolve issues faster.
Of course, all Cummins engines are backed by the largest, most capable support network in North America so you can get great service no matter where you are.
