Thread: supercharger rattling at low rpm

Only place i know that you can get the coupler is from ZZP. Its a stupid easy fix too. I did mine in about an hour and a half when i was a novice mechanic. Also GM will not have this part at all. They will tell you that the Supercharger is not serviceable and it must be replaced or sent off to Eaton.

ZZ Performance

Mine made a horrible chattering noise when idleing before i replaced it.

Here's the writeup i used to replace mine.
