This kit is similar to the LSA or LS9 Fbody offset kit, used the same idler bracket and supports the same HD tensioner setup, but with a different pulley to make the Kong 2650 work with the Fbody/GTO OEM drive system. Works with both 6 and 8 rib with supporting pulleys in 8 rib configuration. 2.65" and larger will bolt on with NO modifications, the 2.45 will need milling or grinding of the casting to clear. Pulleys are stocked in black anodize, but special colors can be done as a custom order.
This kit comes with blower pulley, hardware, additional idler bracket, SuperDuty idler, and associated hardware. Only part needed to complete this drive in 6 rib configuration is a belt and HD tensioner. For 8 rib setups, youll need a balancer, alternator, and power steering pulleys (sold in the store as well), a belt, as well as the HD tensioner.
Since this blower has much more inertia, it will ONLY come with the larger super duty idler pulley, and the HD tensioner setup is a necessity, found here:
