[QUOTE="Toomnymods, post: 8714604, member: 606554"] Hello, I’m planning a large sundown audio build and have everything I need cept for the alternator. Seems GMC thought it was a good idea to get rid of the belt tensioners on the 2020 6.2L L87 engine blocks!! Which this of course all but eliminates me from running a high output alternator on my truck since most alternators have a smaller diameter pulley wheel to get more rpms at idle. Has anyone with a 2020 GMC 6.2L upgraded thier alternator? If so which alternator did you end up going with and which belt?? Please help this is the last thing holding me up from my dream build..
