Description
These Extreme Duty X-Beam forged billet connecting rods are designed to provide the ultimate in strength and durability. These rods start with certified 4340 aircraft-quality steel and are fully CNC-machined on the newest generation of equipment to ensure the removal of all surface imperfections. A precision EDM laser burns a hole from the top of the rod bearing journal to the wrist pin bushing for an extra supply of oil to the piston pin. They are fully stress-relieved and shot-peened to ensure that no stress risers remain. The beam is profiled for weight savings and the cap has been lightened for easier balancing. They are specially heat-treated using a multi-phase process and the rod caps are double-ribbed for added strength. Their rod cap alignment dowels to keep the bearing caps precisely aligned. Howards Cams Extreme Duty X-Beam forged connecting rods are bronze-bushed for floating pins, while 7/16 in. ARP cap screw fasteners secure the caps.
