Product Description
Wiseco Connecting Rod

  • Double forged, 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 and 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
  • 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
  • The kits come complete with rod, crank pin, crank pin bearing, top end bearing and thrust washers
