Cummins 5.9L ISB 24 Valve Engine Applications
By far the most common application for Cummins ISB 24 Valve engines is their use in light-duty trucks. Specifically, these engines were used in Dodge Ram pickup trucks starting in 1998, when they replaced the 6BT models.
Over the course of the next 9 years, the Cummins ISB 24 Valve 5.9 L engines received a number of upgrades which made it an even better fit for its application in pickup trucks. In 2003, a Bosch high-pressure common rail injection system added power and torque while cutting down on engine noise, which made the Cummins ISB 24 Valve one of the most popular engines on the market.
Though light-duty trucks eventually transitioned to utilizing ISB 6.7 L engines in 2009, the ISB 24 Valve remains a popular option for those with older trucks or who are less concerned about emissions.
Beyond this most popular application, some may also use Cummins ISB 24 Valve Engines to power step vans, commercial delivery vehicles, and other similar applications. This is a quality unit that has a wide range of potential applications; it’s not hard to see why it was ranked as one of Ward's "10 Best Engines" in 2004, or why many still feel that it deserves such an accolade.
