We offer a variety of both, over the road truck and industrial
replacement engines for the Cummins ISM 10.8 L units. Our remanufactured Cummins ISM
engines come as a 3/4 long block and are not running trim condition. Our
remanufacturing process strips the core down to the bare block whereas
the camshaft, crankshaft, engine block, connecting rods and cylinder
head are all built back to original OEM spec. The long block is then
finished with new aftermarket gaskets, liners, bearings, pistons and
rings. NOTE: We do include a new oil cooler with the purchase of the ISM long block because it is important to never re-use your old one when swapping over parts due to the potential of dirt/contamination. In addition to the ISM we also remanufacture the Cummins M11 which is the older version of the ISM. Please have your engine serial number handy so we can match up the specs to determine which specific model and configuration you have.
