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 and bottom end rod bores case hardened to 58-62 RC to optimize bearing running surface
Crank pin bearing radial running clearance is optimized to ensure maximum performance
Precision honing ensures ultra round bearing 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 washers, with dimpled design to increase oil retention and reduce friction between rod and washer interface
Crank pin bearings are manufactured from the highest quality hot rolled steel; case-hardened to 58-62 RC
Caged needle roller bearings provide the highest possible rpm
