Bracket needed with 100mm idler???

[04TRCobra]

I have decided to go with a RR or Billetflow 2.93 or 2.8 pulley...

billetflow offers a 100mm idler pulley with a bracket for 109.99
or an idler alone for 54.99


RR offers a 100mm idler pulley for 49.99 but without a bracket nor did i see brackets for sale on this site.

Are brackets needed with 1 100mm idler?

i plan to do the upper with a 100mm idler and a gatorback 74.5 belt. do i need a bracket..or will the RR 100mm idler directly install without a bracket?

If you're talking about the auxilary idler you NEED a bracket. I run a RR 2.8 but went with the BF 100mm aux. Idler and love the setup. I would have gone with Doug's pulley's but was pretty sold on the 2.8 size. BF is the SH*T. I would go with his idler, pricing and quality are top notch.

the auxillary idler is the 1st idler down just to the right of the supercharger pulley...correct??

Yeah but you can add another one, closer to the blower. Is that what you are looking to install, or just change out your aux idlers? If you just want to change out your aux idlers, you will NOT need a mount. If you want to change the upper pulley out and then try to eliminate slippage, most people use a mount, and another idler up top. The mount goes here...

More Idler Pics
I didnt change the two idlers you see in the pic above. I left them, and just added a 3rd idler. Some people go with 3 piece idler set ups... Hope I helped some.
