Hot Rods began with a single connecting rod and has since built a reputation over nearly two decades for excellence in aftermarket replacement rods. With continuously improved designs and an expanding line of applications, Hot Rods remains not only “The Original” but also the best aftermarket replacement rod available.All Hot Rods rods are crafted from 8620 case-hardened steel and undergo a specialized forging process to enhance grain flow and dimensional consistency, ensuring exceptional strength.To improve fatigue durability, Hot Rods rods are shot-peened using stainless steel shot. This process removes stress risers and creates smoothly blended radii, resulting in one of the most durable connecting rods available.Hot Rods kits include only the most advanced and durable bearings. These bearings are case-hardened and silver-coated, matching the toughness and reliability of the rods.Crank pins are subjected to the same rigorous standards, created from hot-rolled ASTM 4115 steel and case-hardened to a hardness level of 58-62 Rc.Key Features:- Double-honed bearing surfaces for reliable, high RPM performance.- Double-drilled small ends for increased wrist pin lubrication.- Bronze bushings in the small end of all four-stroke rods to maximize durability under high loads and prevent galling.- Specially designed vent slots in the large end of all two-stroke rods for improved lubrication.- Side scalloping on the large end to minimize high RPM rod distortion.
