We offer a variety of both, over the road truck and industrial replacement engines for the Detroit Diesel DD15. Our remanufactured Detroit Diesel DD15 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.
