Their precise, no compromise production efforts deliver dimensional accuracy that is second to none. Concentricity and surface finish are the two most desirable features in a high performance crankshaft journal. Each journal must be perfectly concentric to its specified center-line, and journal surface lobing (microscopic peaks and valleys in the journal surface) must be limited to no more than .00006″ to further enhance oil film integrity at high engine speeds.\u003c\/p\u003e\n\u003cp\u003eEvery crankshaft is 100 percent inspected for critical dimensions, and the manufacturing equipment is constantly monitored for tolerance drift and tool degradation.
