Howards Cams GM Duramax 6.6L Extreme Duty X-Beam Billet Rods
• New X-Beam Extreme Duty Design
• American 4340 Certified Aircraft Quality Steel
• American Multi-Phase Heat-Treating
X-beam design for ultimate in strength and durability. Certified 4340 aircraft quality steel and are fully CNC machined on the newest generation of equipment to insure the removal of all surface imperfections. A precision "EDM" laser burns a hole from the top of the rod bearing journal to wrist pin bushing for an extra supply of oil to the piston pin (drilled rod bearings required). Fully stress relieved and shot peened to insure no stress risers remain. The beam is profiled for weight savings. The cap has been lightened for easier balancing. They are specially heat-treated using a multi-phase process to insure the ultimate in strength and reliability. Rod caps are double ribbed for added strength. Rod cap alignment dowels to keep bearing caps precisely aligned. Bronze bushed for floating pins. 7/16" ARP 2000 capscrew (220,000 psi) fasteners secure the caps. The Ultimate Duramax Rod!
