Isuzu's 4J-Series Power Unit is Flexible, Compact & Ready

Isuzu's 4J-Series power unit features significant packaging improvements including a shallow oil pan and lower-mounted air cleaner. The result: a reduced overall footprint —height, length, and width — comparable to our 4L-series power units, but with more horsepower. A new radiator package allows for greater enclosure flexibility, making this unit easier to integrate into existing designs without sacrificing performance.
