I had a asp pulley on my car here for a while and have been tracking a vibration between 1500-2000 rpm. Went through changing motor mounts and clutch/flywheel assembly. I saved the pulley for last because I couldnt see any awkard movements from it and decided to swap it with the stocker today and go figure the vibration is gone ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
This left a bad taste in my mouth for udp's now even still I'd like to purchase another because it seemed to help my car. I'd like to have a ati but money's not good enough for that yet and the only other one it leaves is the powerbond. Any vibration problems from them I don't want to have the same problem as the asp.

Go on ebay and search up atii super damper find an auction where its ati direct selling it and ask if they have any scratch and dent pulleys for your car. I did this after seeing they had a scratch and dent pulley for a corvette. Long story short I ended up paying $215 shipped for an ati pulley with a/c cant beat that right? The defect on mine is that the timing marks are mistamped... doesnt matter to me especially after saving $300.

I like my ati just fine you can tell by looking at all the pieces that its a high quality product everything is machined to precise tolerances and bolts together a certain way. Plus unlike any other underdrive pulley the ati is actually a damper for the crank crankshaft. Also idk why the pic is like that but when I ordered mine it came with the main hub, the outter pulley which is attatched to the damper, the ac pulley and the bolts need to put it all together. It's pretty cool because I installed just the hub at first I was able to heat it up alone without risking damage to any of the damper then after i got it on by hand as much as I could heated up I used the install toll, then just assembled the rest of the pulley. Quick, simple, easy
