CONNECTING RODS
One single connecting rod is where it all began for Hot
Rods and, now, with over a decade of experience, conti-
nously improved designs and an ever expanding line of applications; Hot Rods has continued
to be, not only “The Original” aftermarket replacement rod, but the best aftermarket replacement
rod. All of our rods are created from 8620 case hardened steel. But, in addition to that, our rods
also undergo a process of double forging which helps to improve grain flow as well as dimensional
consistency — and that means a rod of uncompromising
strength.Toimprove fatigue durability, all of our
rods are also shot peened. This process, utilizing a stainless steel shot, helps to remove stress risers
and creates more smoothly blended radiuses. And, in the end, a Hot Rods connecting rod is one of
the most durable rods that enthusiasts and engine builders can buy. However, a rod is only as good
as its supporting parts and that’s why a Hot Rods kit features only the most advanced and durable
bearings, crank pins and thrust washers. Case hardened, silver coated, flat profile KU bearings are used
throughout our entire line and high-quality, long shouldered KZ bearings are used in our two-stroke wrist pin
bearing applications. In short, our bearings are just as tough and reliable as our rods. Even our crank pins are subjected to the same rigorous stan-
dards as our rods and bearings. Each Hot Rods crank pin is created from hot-rolled ASTM 4115 steel and case-hardened to a level of 58–62 Rc.
