Is it the alternator that is out of alignment or the idler pulley? The alternator can be adjusted with shims. The idler pulley needs a support bracket to prevent it from bending under the tension of the belt.
Yeah....that pulley requires a support bracket to keep it aligned and prevent it from bending under load. There are products out there designed to take care of that. I'm no longer a vendor on this forum.....
Same here for the CTS-V alternator bracket and Shane's Idler pully setup. I'm running a 625 hp LS3 and heard the higher HP application would have that flexing/bending issue so I went this path from the beginning.
