Hot Rods crankpins are manufactured from hot-rolled ASTM 4115 and case hardened to 58-62 Rc
Hot Rods works directly with their bearing factory’s engineering department to bring you the latest in caged needle roller bearing designs for high rpm
Uniquely designed big end uses strategically located side scalloping and vent slots to minimize high rpm bearing race distortion
Hot Rods are double forged to improve grain flow and maintain dimensional consistency
Shot-peened to eliminate surface stress risers and to smoothly blend the rod forging’s radiuses together, which unlike hand-ground and polished rods produces more consistent dimensioning and surface finish for superior strength under heavy loads
By shot-peening the connecting rod’s surface, fatigue durability is improved two times over a forged rod and over eight times when compared to polished rods
Double honing produces an ultra-round (50 millionths) bearing surface, producing a reliable high-rpm connecting rod
Small ends are double drilled to supply extra lubrication and cooling to the wrist pin bearing, which is especially important when the piston crown is close to the wrist pin bearing
Also feature silver-coated bronze phosphor thrust washer
Rod assembly sold complete with rod, crankpin, crankpin bearing, top end bearing and thrust washers
