Hot Rods began with a single connecting rod and has since evolved over nearly two decades to become the leading aftermarket replacement rod. With continuously improved designs and a broadening range of applications, Hot Rods is not only "The Original" but also the best in aftermarket replacement rods. Materials and Construction: All Hot Rods rods are crafted from 8620 case-hardened steel. This is further enhanced by a specialized forging process that improves grain flow and dimensional consistency, resulting in rods of exceptional strength. Durability Features: - Each rod is shot peened with stainless steel shot to remove stress risers and create smoothly blended radii, significantly improving fatigue durability. - Hot Rods kits include bearings that are case-hardened and silver-coated for unmatched toughness and reliability. - Crank pins are made from hot-rolled ASTM 4115 steel and are case-hardened to 58-62 Rc, ensuring robust performance. Design Enhancements: - Double-honed bearing surfaces provide reliability for high RPM applications. - Double-drilled small ends enhance wrist pin lubrication for better performance. - Bronze bushings are featured 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 improve lubrication. - Side scalloping on the large end minimizes distortion at high RPMs. Hot Rods connecting rods are engineered for enthusiasts and engine builders seeking the utmost durability and performance. With advanced construction techniques and rigorous standards, Hot Rods continues to set the benchmark in aftermarket replacement rods.
