The WEAPON-X pulley combos have powered some of the fastest CTS Vs on the planet. We have tested various pulleys to maximize your modifications from stage 1 to stage 5! Pick your poison, but if you need help, call our supercharger specialists and we can make sure you're running the best combo for your setup!  Stage 3 pulley and up requires additional supporting modifications.

Innovators West now offers a Harmonic Damper for the 2009 and Up Cadillac CTS-V. The damper was designed with an adapter plate that accepts the interchangeable crank pulleys that can raise your boost pressure in correlation with crank rotation!
