This high-performance crankshaft assembly is engineered to meet OEM specifications with precision and reliability, featuring advanced materials and design enhancements to maximize strength, durability, and performance. It is precision-trued to OEM specifications and factory assembled. The shot-peening process reduces residual stresses and smooths rod forging surfaces. A corrosion-resistant surface treatment ensures long-lasting durability. Optimized crank pin bearing radial clearance maximizes performance. Precision honing creates an ultra-round bearing surface. Precision-engineered oiling slots enhance rod strength and bearing life. Double-drilled small ends provide improved lubrication and cooling, reducing top-end thermal distortion. Silver-coated bronze phosphor thrust washers with a dimpled design offer better oil retention and reduced friction. Crank pin bearings are made from high-quality, case-hardened hot-rolled steel (58-62 RC). Caged needle roller bearings allow for the highest possible RPM. Precision-machined crank webs. Includes top-end bearing and gasket.
