Ok I have choose to got with the ATI Harmonic Damper due to my existing one wobbling. Everyone on here seems to say that ATI is the way to go if I don't want to have the problem reoccur. Are these are the correct parts required to do the install for my vehicle?

1) ATI Harmonic Damper 917246
2) ATI Removal/Install Kit 918999
3) ATI Installation Stud 918999SC
4) ATI Harmonic Balancer Bolt Kit 951499

Is there anything else I need to do this install? Also I need to replace the crank seal, which brand is recommended?

use the GM front cover seal and things will be a lot easier to do if you have the GM Kent- Moore flywheel holding tool p/n J 42386-A to prevent the engine from turning over when removing and installing crank bolt.GM exclusively uses ATI hb's on their crate engines including the LS series at any power level when not wanting to risk hb failure.check your GMPP catalog
