The ATI Performance Crank Hub Steel LS1 Y-Body w/28 Tooth Pulley is a precision-engineered crankshaft accessory designed for LS-platform engine builders and performance enthusiasts who demand reliability in high-horsepower applications. This steel crank hub serves as the critical interface between your engine's crankshaft and the serpentine belt drive system, making it essential for proper accessory drive functionality.
Manufactured from durable steel construction, the ATI crank hub features a precision-machined 28-tooth pulley configuration, delivering accurate accessory drive ratios for alternators, power steering pumps, water pumps, and air conditioning compressors. The 28-tooth design optimizes serpentine belt wrap and tension distribution, reducing friction losses and improving overall drivetrain efficiency.
This crank hub is particularly beneficial for those building restomods or street performance engines, especially when preparing for forced induction. Its compact dimensions and lightweight specification help keep rotating mass minimal while maintaining structural integrity under increased loads.
