This front drive kit will let you run a factory LS9 blower on the GTO and Fbody belt spacing. Comes in your choice of 2.45", 2.65" and 2.85" diameters (stock is 3.1" and can be done on special request). Kit comes with your choice of pulley, pulley hub and hardware, as well as an idler bracket, hardware, and an idler. These can be ran in 6 rib or 8 rib configuration using either stock parts, or 8 rib kits from vendors such as Innovators West. The 6 rib and 8 rib kits are basically identical, minus a change to a wider idler and hardware (supplied) for the 8 rib kits.
This is essentiall the same kit for the GTO/Fbody spacing that we already offer for the LSA blowers, just modified with a different pulley to make it work on the LS9 setup.
