About this part

Product Details

This ATI crank hub is made from steel and features a HT (heat-treated) finish for added durability. It's designed for SB blower drive applications and includes a 4-bolt pattern with a 28K/W designation, indicating its specific use in certain supercharger setups. This component is crucial for proper crankshaft timing and power transfer when you're building or modifying an engine for forced induction.

The steel construction makes this hub a solid option for handling the increased stresses associated with blower drives. Its heat-treated finish further enhances its ability to withstand demanding operating conditions. The 4-bolt pattern is a common standard for many blower drive systems, ensuring a secure connection to your crankshaft pulley and supercharger drive assembly. This part is a well-built piece that aims to provide reliable performance in high-stress engine builds.
