Wiseco WPR2403 Connecting Rod Kit

Double forged, Wiseco connecting rods maintain superior dimensional consistency through improved grain flow. 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 galling. The bottom end rod bores 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.
