ATI Performance Products Supercharger Pulleys: Engineered for Boost

ATI Performance Products has spent decades earning its place at the top of the drag racing and high-performance aftermarket. Founded as a transmission and performance component manufacturer, ATI brings over 50 years of racing experience to every product it makes — and that heritage carries directly into its supercharger pulley lineup.

The ATI Super Pulley: A Smarter Approach to Belt Drive

The crown jewel of ATI's supercharger pulley range is the patented Super Pulley. The ATI Supercharger Super Pulley is designed to eliminate blower belt failure on high boost applications by allowing the supercharger to freewheel whenever it's spinning faster than engine RPM. This is a critical advantage during closed-throttle events — such as gear changes or lift-off moments — where belt stress and snap-back forces can destroy conventional pulley setups.

This unique design allows the supercharger to "freewheel" when the throttle is closed, making it ideal for both competition and street applications, utilizing ATI's Superior Sprag Technology. That sprag clutch mechanism is the same concept trusted in transmission and torque converter applications — adapted here specifically for supercharger drive systems.

Serpentine Supercharger Pulleys: Dialing In Your Boost Level

Beyond the Super Pulley, ATI manufactures a comprehensive range of serpentine supercharger pulleys engineered for precise boost management. ATI serpentine supercharger pulleys are designed to drive boost performance, with overdrive models — smaller pulleys — available to spin the blower faster for more power.

The lineup spans a wide variety of configurations, including 11-groove serpentine pulleys with 15% and 20% overdrive options for the Chevrolet LT5, as well as sprag-equipped HTD belt pulleys for ProCharger reverse-rotation applications. Additional fitments include 8-groove serpentine options for Cadillac applications and OE-style crankshaft pulleys for GM Vortec Truck and SSR/Trailblazer LS1/LS2 platforms. Whether you're building a dedicated track car or a high-output street machine, ATI's range lets you fine-tune boost output with confidence.

Construction Quality and Platform Coverage

ATI supercharger pulleys are typically constructed from steel with a black oxide finish, delivering corrosion resistance and long service life even under the heat and stress of sustained forced induction use. ATI holds over a dozen U.S. Government patents, and all manufacturing takes place in-house at their facility outside Baltimore, Maryland — with more than 30 CNC machines ensuring total quality control.

Platform coverage includes popular GM applications like the LT4, LT5, LSA, LS1, LS2, and Cadillac CTS-V, making ATI one of the most relevant supercharger pulley suppliers for GM performance enthusiasts. ATI supercharger pulleys are ideal for both competition and street applications.
