This kit allows you to run an LSA blower on any LS engine with an Fbody or GTO front accessory drive. This kit does not move or delete any factory front drive parts. Does not require shimming, spacing, or deleting ANY parts like some other kits on the market. Comes with pulley and hub, brackets, spacers, and an additional idler. Also includes an upper 8 rib LSA pulley in 2.45" or 2.35". Belt not included, but measurement procedure is included in the manual.
Pulleys are anodized black as stocked standard options, but clear and custom colors are available. (some delays might occur with clear and custom colors)
Please Note: These pulleys are made in 8 rib, but work with stock 6 rib belts as well as upgraded 8 rib setups. This kit comes with ONE additional 8 rib OKW billet idler, you will use your stock alternator idler in the 6 rib setup. For 8 rib setups you'll need an additional 8 rib OKW Billet idler, a Continental 49102 idler or use one from Innovators West, etc. The idler bracket will also interfere with AN converted power steering pump fittings, the stock style hardline must be used at the pump, and if AN hoses are needed, a fitting needs to be brazed onto the stock line. AN fittings WILL NOT CLEAR THE IDLER BRACKET!!
If you are using one of the knock-off pulleys from another supplier, we do sell just the idler kit alone, without the blower pulley. Just select the correct option from the menu. This option comes standard with our single row bearing HeavyDuty idler which is fine in 95% of the installs. If you want the SuperDuty dual row bearing upgrade, make sure to select that option in the drop down. Both idlers work with either 6 or 8 rib installs.
It is highly recommended to use the HD Tensioner setup with this kit as well. It can be found here:
