What is the main purpose of a crank hub?

A crank hub connects the crankshaft to other engine components, like the timing belt or chain. This specific ATI hub is designed for Audi race engines to ensure precise synchronization between the crankshaft and camshaft under demanding conditions.

What does the 'ST' designation mean?

The 'ST' designation typically indicates that this crank hub is specifically intended for racing applications. It suggests a design and construction optimized for the higher stresses and performance requirements found in competitive motorsport.

What is the benefit of a 26-tooth cam drive?

A 26-tooth cam drive offers a specific gear ratio for camshaft synchronization. In race engines, this precise tooth count is crucial for achieving optimal valve timing and engine performance, especially when working with specialized camshaft profiles.
