Proven reliability and durability

Our medium-duty truck engines have been tested and proven over the course of more than 30 years, so it’s no wonder how we power more trucks any other engine. No one can touch the proven track record of performance on our unparalleled medium-duty lineup, and no one comes close to Cummins service and support. Others talk a big game, but only we deliver bigtime uptime.
