Integrated Engineering is proud to manufacture the forged H beam connecting rod, the highest quality connecting rod set available for European applications at a reasonable price. This is accomplished through careful industry leading design practices, manufacturing, and strict quality control processes. For years Integrated Engineering H beam rods have been the workhorse of our line-up providing excellent performance right out of the box. With very high reliability even in extreme applications our H beam design has remained the top choice in builds up to 700+ BHP, even found in four-cylinder cars into the 800+ BHP range.
The material specification and treatment is equally important to producing a quality forged connecting rod. Integrated Engineering H beam rods feature 4340 Chrome Moly steel, formed into shape using a 2 piece forging for the highest possible fatigue life. The material is multi-stage heat treated to ensure the highest possible fatigue strength as well as good dimensional stability. This feature ensures that our big ends stay round for a lifetime of bearing trouble free service. Following this pattern of high quality, included ARP 2000 rod bolts are standard in all of our connecting rod applications.
OPTIONAL RIFLE DRILLING
To keep wrist pin wear at the minimum, all of our H Beam Forged rods are available in a rifle drilled option. Rifle drilling forces pressurized oil through a small orifice placed vertically through the rod and further lubricates the pin and bushing. This extra oiling causes less wear and friction between the rod and piston and increasing the life of the internals. We highly recommend the rifle drilling option for street-driven cars, as they typically see more mileage put on them, but works well to extend pin life on any setup.
