Our HP Reman Extreme 5.9 Cummins come fully assembled including oil pan rear crank seal front cover and crank seal, and oil filter housing. With our Stage 1 High Performance Cylinder Head. We include a street/towing camshaft. Customers typically see a 200-300 degree drop in EGT and a fuel economy increase from the additional air flow. We assemble these engines with the best parts available in the industry including Cummins, Mahle Clevite, and ARP.
HP Reman Extreme 5.9 Cummins Long Block are disassembled, crack checked, blasted and cleaned before we start machining. Each block is CNC bored depending on the application, line bored, surfaced as needed, and torque plate honed to exact spec. We use custom ARP 9/16″ head studs to give the best head to block seal possible. D&J Stage 1 Performance Cylinder Heads are completely disassembled and checked for cracks. Stock seats are removed and replace with our extra-large heavy-duty seats. The head is machined for thread in soft plugs and 5-axis CNC ported. All cylinder heads get a CNC high performance valve job, and pressure checked before being completely assembled and painted.
All D&J Precision Machine HP Reman Extreme long blocks are blueprinted, balanced, oil clearance measured, rings file fit. HP Reman Extreme Cummins long blocks are painted black and are shipped pre-lubed with break in oil and filter included.
Available for all common rail from 2003-2007.
