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!
