The journey of crafting each Performance 5.9 and 6.7 Cummins Long Block begins with a rigorous process. We start by disassembling and thoroughly inspecting each part for any flaws. The engine block undergoes a series of precise machining processes, including CNC boring, line boring, and surface machining, tailored to your application. Our meticulous attention to detail includes the addition of Fire Ring grooves and custom ARP 9/16″ head studs, ensuring an unparalleled seal between the head and the block.
Our Stage 2 Performance Cylinder Heads are a testament to our commitment to quality. We start by stripping them down and inspecting each component. The stock seats are replaced with our heavy-duty alternatives, and the head is re-engineered for our Stage 2 Billet Intake Manifold and expertly 5-axis CNC ported. After hand lapping and pressure checking, these heads are reassembled to perfection.
Our Standard Performance 5.9 and 6.7 Cummins Build is a marvel, featuring our X-Beam Billet Rods, OEM Cummins Pistons, and much more. The 250 CFM Stage 2 High Performance Cylinder Head is a work of art, offering unmatched airflow and performance enhancements.
And for those who want to take their engine to the next level, we offer a range of optional upgrades, including our D&J Billet Freeze Plugs, Billet Timing Cover, and LED Valve Cover.
Remember, shipping varies per order, and you can send in your core components to waive the core charge.
