  1. This is my 2019 AT4 leveled with Bilstein 6112’s and 2” MotoFab top spacers. It initially was 3/4” high in the front but after 100 miles settled to perfectly level.
  2. Thanks! This is good to know. I still would have had to use a spacer to get the 2” I needed for the level as the Bilstein 6112’s for the AT4 only go up to just over an inch.
  3. This list is for a 2019 Sierra AT4 with the 6.2, make sure these are correct for your truck. Two of each are required and you do not need the lower insulator if you are installing 6112’s. 84171380 Front suspension strut bumper 23344927 Front spring lower insulator 84171377 Front shock absorber boot 84458268 Strut Mount 11601789 Top Nut
  4. Better. The ride overall is a touch firmer but has none of the pogoing in the front or the choppiness in the rear. I think it makes it much more comfortable.
  5. So I just got my truck back from having a set of Bilstein 6112’s with a MotoFab 2” top spacer installed along with a set of Rough Country UCA’s. I already have Bilstein 5100’s in the back. I went with 6112’s simply because I was tired of waiting on the 5100’s for the front and found these in stock. they are installed on the lowest snap ring groove as I want to keep preload to a minimum for the best ride quality. axle angles are ok. I don’t do any serious wheeling so I expect them to last. I was going to do the install myself but compressing those big springs gave me the heebie
  6. Install a small spacer. Use a good brand that is hub centric and you should have no issues. I’ve got a set of Bora spacers on the way for my truck.
