• Precision-trued to OEM specifications and factory assembled
• Connecting rods are double-forged to 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 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, premium main bearings and a complete bottom end gasket set that includes all seals and gaskets needed to do the job
