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". Pulleys are anodized in house any color. Belt not included, but measurement procedure is included in the manual.
Pulleys are anodized clear or black as standard options, but custom colors are available.
Please Note: These pulleys are made in 8 rib, but work with stock 6 rib belts as well as upgraded 8 rib setups. The 6 rib kits come with ONE additional 6 rib idler, the 8 rib kits come with ONE 8 rib idler, you will use your stock alternator idler in the 6 rib setup, or have to source a second 49102 idler or use one from Innovators West, etc.
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 does NOT come with the idler, since some combinations that use the idler bracket will use a ribbed idler (PS delete on N/A setups for example). The smooth idler is Dayco 89052 and the ribbed one is Dayco 89015, any parts store can cross reference these.
