Cummins ISX Used Diesel Engine

Cummins ISX Used Diesel Engine


We offer a variety of used Cummins ISX used diesel engines that fit both heavy duty on-highway class 8 trucks, RV applications and industrial/genset use. The Cummins ISX replaced the N-14 in 2001 and came in multiple different models over the years including the smaller ISX 12, Signature Series, ISX 15 and the later X-15 models. The early ISX engines used a dual over head camshaft design but were replaced with a single camshaft in later years.

Our used Cummins ISX engines are all thoroughly inspected and test run to ensure the quality of the components, this especially is important with the EGR and Turbocharger to ensure excess soot doesn’t clog the systems. The majority of our good used ISX runners are around 400-500 HP and pulled from Freighliner, Volvo and Peterbilt chassis.
