ATI Super Dapener on an LS3
I had the notorious crank pulley wobble on my Camaro LS3. I paid a shop to install it since I didn’t have a torque wrench that would go up to 239 ft-lbs. My wife even noticed that our Camaro ran and idled smoother.

no bolts included
This item comes with a packing slip that says the bolts are in the cardboard or inside the hub. There were no bolts to assemble this packaged in mine. Returning or going to have to get some bolts sent over. Also says you need a t 40 plus driver. I don't have one so I will have to get that as well. Some take a t40plus some take a t45plus. regular t40 will not work.

Typical high quality from ATI
Great fit and finish. Probably my 10th ATI dampener and it is top notch just like the ones before it.
