Description

A factory-assembled crankshaft kit supplied with main bearings and a gasket set for complete bottom-end service. Precision-trued to OEM specifications, it incorporates advanced surface treatments, lubrication features and tightly controlled clearances to support durability and performance under high-RPM operation.

Features

Precision-trued to OEM specifications and factory assembled
Connecting rods are double-forged to maintain superior dimensional consistency through improved grain flow
Shot-peened to eliminate residual stresses and smoothly blend rod forging surfaces
Corrosion-resistant surface treatment
Top and bottom end rod bores case-hardened to 58–62 RC to optimise bearing running surface
Crank pin bearing radial running clearance optimised to ensure maximum performance
Precision honing ensures an ultra-round bearing surface
Precision-engineered oiling slots maximise 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 rod and washer interface
Crank pin bearings manufactured with the highest-quality hot-rolled steel — case-hardened to 58–62 RC
