Eagle Extreme Duty (XD) rods feature the same time-tested 3rd generation design, but further surface polishing improves fatigue life by removing microscpic pits and inclusions where fatigue cracks begin. Eagle utilizes large-scale manufacturing to keep costs low, but only uses ASME-certified 4340 steel, ARP bolts, and silicon-bronze bushings. This means that Gen I and Gen III/IV connecting rods are interchangeable, because they share the same big-end housing diameter. Some bell housings will not allow the use of a 168 tooth flexplate, and will require a 153 tooth size. Because the LS has fairly even cooling and excellent fuel distribution (with MPFI) the pistons usually stay cool and live a long happy life under moderate boost.

The entry-level SIR I-beam rods are forged from 5140 steel, and they can handle up to 700 hp. I'll make sure it's addressed. He continued to operate the machine shop and build engines for us while we continued selling online under the user ID of skipwhite and the store name of whiteperformance1. Unfortunately, very few engine builders and hot rodders have gone through the painstaking efforts necessary to test this theory. 025 to achieve a zero deck. A billet rod starts out as a single ingot of forged steel, aluminum, or titanium and is machined into the final shape of the rod. By the way, this taper break-point theory applies to all stroker engines. Pro LS Profile: Summit Racing Makes Choosing a Forged Piston for Your LS Engine Easy. Most stock LS rods must be press-fit onto the pistons, which racks up another $80 in labor.
