The ATI Performance Aluminum Crank Hub for Small Block Chevy (SBC) is designed for engine builders and performance enthusiasts who require reliable components. This crank hub is a key interface between the crankshaft and accessory drive system, managing loads from the alternator, water pump, and power steering while maintaining precision under high RPM conditions.
Constructed from aluminum, this crank hub minimizes flex and harmonic distortion, which can be introduced by cheaper cast-iron alternatives. Its lightweight design, weighing just 1.05 pounds, helps reduce parasitic drag on the crankshaft while ensuring durability. The precision machining of the hub guarantees balanced weight distribution and mitigates run-out issues, enhancing belt tracking and accessory bearing life.
Ideal for both naturally aspirated and boosted SBC platforms, this hub is suitable for stock restorations, LS swap foundations, or dedicated race applications. It provides dependable harmonic control and accessory synchronization throughout the full RPM range, making it a valuable component for serious engine builds.
