If you are using the GripTec LPE pulleys for your LSA or LS9 supercharger then it is necessary to have a LPE Hub. If you are using a ZPE MKII pulley you will want the ZPE Hub not this LPE Hub.
This hub supports:
- 2009-2013 (C6) Corvette ZR1 (LS9 2.3L blower)
- 2009-2015 (V2) Cadillac CTS-V (LSA 1.9L blower)
- 2012-2015 (Gen 5) Camaro ZL1 (LSA 1.9L blower)
A Griptec upper pulley upgrade is a cheap and effective way to boost power.
The hub comes with a set of 10 screws for weight for mounting your blower pulley.
To install the 10 bolt hub you must remove your supercharger snout or front cover and use a pulley puller to remove the stock pulley. You must machine clearance on the front cover before the new 10 bolt hub can be pressed onto your stock OE supercharger shaft.
