Product Description

The ATI 916105 8-rib serpentine supercharger pulley provides a 5 % overdrive to the LSA supercharger on 2009-2015 Cadillac CTS-V and 2012-2015 Camaro ZL1 models. Precision-engineered from machined aluminum with a steel hub, this OEM-style pulley integrates with the ATI Super Damper harmonic balancer to drive the blower faster, resulting in higher boost and horsepower.

With a measured drive diameter of approximately 8.295 in, it matches OEM belt size and geometry while delivering upgraded boost response. To install, you'll need a compatible ATI damper and standard belt routing. Designed for high RPM stability under performance conditions, this pulley is a trusted choice among LSA-powered performance builds.
