I'll have to check tension on mine, sounds like they want it tight

Me to, I have the Kwik mount and just today it started to squeal. Belt dressing helped but it’s not the answer
Thanks for the Part #

We installed the updated Kwik mount and belt indicated in their directions and the squeal has stopped! Summit sent the new bracket in a couple days and took the old one back for no charge. No shims needed in our case.

Excellent, the new bracket seems to do the trick; glad you got it resolved.

Well, here is my update. Finally got my truck fired up and running/driving(around the block anyways). I have ran it quite a bit idling in the garage and around the block a few times now and no squeal. I don't have that new bracket above that I can tell. I bought my VA kit a year ago or maybe 10 months.

Here is some video of my setup.

And here are the instructions I followed:

Finally fixed my squealing..... Installed the Holley bracket. I would highly recommend there brackets to anyone doing a ls swap. Took about an 1 hour to install, high quality machine work, no flex in bracket and belt tracks straight and noise free!!

Mine started squealing again a while back. I ordered a smooth idler pulley from Street Machinery and then loosened the entire KWiK mount, pulled up and back on it and tightened it in place starting with the top bolts into the head. Also inserted a thin washer between the lower tensioner mounting point and the bracket. So far it’s all peace and quiet! (Of course, the aluminum spacer between bracket plates fell out and got stuck down under the motor, had to jack up the truck to reach all around and find the damn thing...). Wife and I drive around yesterday (escapees from quarantine!) for almost an hour and it stayed quiet.

What part number bracket did you use? Any pics?
Thanks

I ordered the ict billet mount and it squeals when the compressor is on. They claim it’s the compress but two new ones later it’s still squealing.
