What is the purpose of a crank hub?

A crank hub connects the crankshaft to the harmonic balancer or other front-end accessories. It's crucial for ensuring the crankshaft's rotation is accurately transferred to drive components like the water pump, alternator, and power steering.

Why is steel a good material for this crank hub?

Steel offers a strong and durable material choice for engine components that experience significant stress. Its robust nature helps prevent deformation or failure under high RPMs and torque loads common in performance engines.

What does 'Gen 4 5 (2) 3/16 Keys 2008+' mean for fitment?

This indicates the hub is intended for the fourth and fifth generations of Viper engines, specifically those manufactured in 2008 and later. The '(2) 3/16 Keys' refers to the keyway system used for securing the hub to the crankshaft, which requires two 3/16 inch keys.
