When standard tolerances aren't enough, the ATI Performance .005 Undersize Steel Crank Hub provides the extra precision needed for a perfect fit on your Small Block Chevy or Pontiac 4-cylinder engine. This undersized hub is specifically designed for crankshafts that have been polished or require a tighter interference fit to ensure the harmonic balancer remains securely seated at high RPMs.
Using an undersized hub is a common practice among professional engine builders to compensate for minor variations in crankshaft machining. By providing a tighter fit, this ATI Performance hub prevents the harmonic balancer from spinning on the snout, which can cause catastrophic engine failure. Don't leave your engine's health to chance—ensure your rotating assembly is locked down tight with this high-performance component. ATI Performance continues to lead the way in engine balancing technology, and GGCRACING is proud to offer their professional-grade parts to our customers.
