MECHMAN Posted September 16, 2021 Report Share Posted September 16, 2021 Needing to collect more data on these modern vehicles. If you have one or know of someone that does, please post or email me. As usual, other brands "say 14-18 applications fit" so they can sell you something and take your money. We prefer to provide a product that will work as much as factory as possible. The fact is, the stretch belt applications do not provide the correct tension for 200+ amp alternators, especially not 400's. We have a solution as we have a few in the field with our tensioner kit, but we're trying to establish a database of vehicles it will fit on. Main vehicles requested are: 2019> Silverado / Sierra 1500, 2500 3500 with 5.3, 6.0, 6.2 and 6.6 Diesel 2019> Tahoe / Suburban / Yukon / Escalade with same engines as above. The area in GREEN is where there are supposed to be a spring tensioner and idler pulley. We're finding some models have threads and some do not. Any help is certainly appreciated!

kickass audio Posted February 5 Report Share Posted February 5 I am late to the party but I have a 2023 Silverado RST with the 5.3l and it does not have the tensioner pulley and I never noticed it. I was planning to re-use my 370A alternator from my 2014 silverado 1500 5.3l but I guess I can't now. Thanks GM for the shaft haha. What is this adapter kit you speak of?
