Precision-trued to OEM specifications and factory assembled. Connecting rods are double-forged for superior dimensional consistency through improved grain flow. Shot-peening eliminates residual stresses and smoothly blends rod forging surfaces. Features corrosion-resistant surface treatment. Top and bottom end rod bores are case hardened to 58-62 RC to optimize bearing running surface. Crank pin bearing radial running clearance is optimized for maximum performance. Precision honing ensures an 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 the 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 the rod and washer interface.","attributes":[{"label":"General Product Group","value":"Crankshafts & Parts"},{"label":"General Product Type","value":"Crankshaft Bottom End Kits"},{"label":"Variant Id","value":"250327"}],"image":"https://b69270dd6ab1.blob.upstash.io/oracle/oro2u/56-230_2EWI_2ECBK/682ff07c80222680.jpg","images":["https://b69270dd6ab1.blob.upstash.io/oracle/oro2u/56-230_2EWI_2ECBK/682ff07c80222680.jpg","https://b69270dd6ab1.blob.upstash.io/oracle/oro2u/56-230_2EWI_2ECBK/db00a39ef10ff843.jpg","https://b69270dd6ab1.blob.upstash.io/oracle/oro2u/56-230_2EWI_2ECBK/62d6d95f07c82147.jpg","https://b69270dd6ab1.blob.upstash.io/oracle/oro2u/56-230_2EWI_2ECBK/91325ba1347eda00.jpg"],"description":"Wiseco Crankshaft Bottom End Kit with Bearings and Gaskets - WPC139.
