Lingenfelter offers this 10 bolt 8 rib 2.38 inch diameter pulley for the CTS-V or Camaro ZL1 LSA 2009-2014 that allows you to overdrive your supercharger by 26%. We also offer a 2.55 inch diameter which will provide a 18% overdrive rate.
The supercharger snout must be machined to allow clearance with this smaller diameter pulley. The Lingenfelter 2.38 diameter 10 bolt pulley requires the Lingenfelter 10 bolt hub kit which is sold separately, machining is required to install the hub kit.
