Certified 8620 AISI steel provides superior strength
Crankpins are manufactured from hot-rolled ASTM 4115 and case hardened to level of 58-62Rc
Feature the latest in caged needle roller bearing designs for high rpm longevity
Uniquely designed big end uses strategically located side scalloping and vent slots to minimize bearing race distortion at high rpm
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
Shot-peened to eliminate surface stress risers and to smoothly blend together the rod forging's radiuses
Double honing produces an ultra-round bearing surface for reliability at high rpm
Most rod assemblies are sold complete with rod, crank pin, crank pin bearing, top-end bearing and silver-coated bronze phosphor thrust washers
