Performance Series 5.9 Cummins Common Rail Long Block

Description

D&J Precision Machine Performance series 5.9 Cummins Long Block.

Our Performance 5.9 Cummins come fully assembled from oil pan to rocker box with our X-Beam Stock Length Billet Rods and our Stage 2 High-Performance Cylinder Head. We custom-build this engine for your application, with the best parts available in the industry including Cummins, Mahle Clevite, and ARP.

Our Performance 5.9 Cummins Long Block is disassembled, crack-checked, blasted, and cleaned before we start machining. Each block is CNC bored depending on the application, line bored, surfaced as needed, CNC machined for the girdle and studs, and torque plate honed to exact spec. Fire Ring grooves are cut into the cylinder head along with custom ARP 9/16″ head studs to give the best head-to-block seal possible. D&J Stage 2 Performance Cylinder Heads are completely disassembled and checked for cracks. Stock seats are removed and replaced with our extra large heavy-duty seats. The head is machined for our Stage 2 Billet Intake Manifold and 5-axis CNC ported. All cylinder heads are hand-lapped and pressure-checked before being completely assembled.

All D&J Precision Machine Performance Long Blocks are blueprinted, and balanced, oil clearance measured, and rings are file fit. Performance Cummins long blocks can be painted any color and are shipped pre-lubed with break-in oil and filter included.

Available for all common rail from 2003 to 2007.
