Connecting Rods

Double forged connecting rods maintain superior dimensional consistency through improved grain fl ow. Shot peening eliminates residual stresses and smoothly blends the rod forging surfaces.
· Corrosion resistant surface treatment.
· Top end of rod is bushed for oil retention and eliminates pin gauling. The bottom end rod bores are case hardened to 58-62 RC to optimize bearing running surface.
· Precision engineered oiling slots maximize rod strength and bearing life.
· Double drilled small ends provide the piston pin with extra lubrication and cooling - Reducing distortion of top end due to thermal transfer from the piston.
· Silver coated bronze phosphor thrust washer, with dimpled design to increase oil retention and reduce friction between rod and washer interface.
· The crank pin bearings are manufactured from the highest quality, hot rolled steel. Case hardened to 58-62 RC.
· The caged needle roller bearings provide the highest possible RPM.
