Choice of 2.5 or 2.4 upper pulley, 100mm idler, and isolator
Looking for more boost your your 2009-15 Cadillac CTS V or 2012-15 Camaro ZL1? Change the ratio the blower spins with one of these upper pulleys which have interchangeable rings so the snout doesn't have to come off to change pulley size in the future and they have a completely stock appearance for the dealership's eyes unlike their competition. If you would like help matching a size to your needs, see our packages for upper and lower pulley combo and supporting mods needed or feel free to email sales@weapon-x.com for assistance!
The supercharger snout must be removed from the supercharger case and the original pulley must be removed and the new pulley installed using a press. No gaskets need to be replaced and generally no lubricant is lost during this procedure. As part of this changeover, we highly recommend replacing the original snout isolator, which is problematic and prone to make noise. Our solid isolator is precision-machined from very high grade materials and installs as a direct replacement for the original.
