•Precision-trued to OEM specifications and factory assembled
•Shot-peening eliminates residual stresses and smoothly blends the rod forging surfaces
•Corrosion-resistant surface treatment
•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 increase oil retention and reduce friction between rod and washer interface
•Crank pin bearings are manufactured with the highest-quality hot-rolled steel -- case hardened to 58-62 RC
•Caged needle roller bearings provide the highest possible RPM
•Precision-machined crank webs
•Crankshaft comes with top-end bearing and gasket
