  1. I waited for two years for the 3.0 to become available. I absolutely love my AT4. The 3.0 does everything I need and more. I can get 25+ miles per gallon in normal driving and it I can tow a trailer with tractor that comes in at about 6000 pounds like it’s not even there. Is it quick like a 6.2? No. Does the feel of 480 pd ft of torque at 1500 rpm push you back in the seat? Heck yes. It’s also quiet, but still let’s you know it’s an oil burner.
  2. Did your 2019 use the stock upper control arms? That angle doesn’t look good. Your 2020 kit looks ideal, but it should for the cost. Here is a pic of my 2020 with the RL level kit with new upper control arms. The CV angle is not severe like your 2019 was. This kit didn’t come out until 2020, so I am curious if maybe you used something different. This kit splits the spacers between the top and bottom of the coil over. Putting a spacer on the bottom of the coil over moves the control arm further away while leaving the ball joint and cv angle somewhat unchanged. I agree that lowering the front diff is the correct way to go to correct the cv angles. I must disagree with your comment that the upper control arm does not impact CV angles. The longer arms push the top of the spindle outward to help center the lower ball joint. This also changes the angle on the cv axle.
  3. ReadyLIFT has a leveling kit specifically designed for the AT4/Trail Boss that comes with new upper control arms to allow for proper ball joint and C/V axle angle. There is no note about not using Auto mode. I have this kit, and have had no issues with it. I do see the note about not using the auto mode in the ReadyLIFT 2.0” lift kit for the AT4/TrailBoss that uses the same front end components as the level kit. It’s also in every other lift kit made by them. I am curious if the reason has something to do with the raised center of gravity on the truck, and this is a way for them to cover themselves in the event of an accident. https://www.readylift.com/2-25-front-leveling-kit-w-control-arms-at4-trail-bossgm-1500-truck.html
  4. I installed the auto stop eliminator after the truck turned off and then didnt restart until I put it in park and started it myself. Besides that, it’s a government mandated item, so I automatically don’t like it. Haha
  5. I see you are in Alabama. Me too. I got mine from Bentley GMC in Huntsville. Their parts department said the part was on backorder, but that there were still ways to get the part. They got every single piece of the kit for me in two days. Their number is 256-536-2475.
  6. Nice truck! Ive got 9k on mine and absolutely love the 3.0. I added the body colored “flares” and mirror caps. It just didn’t look right to me with the matte black flares and chrome mirror caps. Enjoy the truck.
  7. Has anyone put one in a 3.0 Duramax truck? My kit went in with no issues, with the exception of the cable from the battery to the fuse block. I know it's probably me, but I swear that my truck does not have the provision for passing the cable through the firewall where the directions state. It's probably there, but it's buried by a coolant reservoir for the turbocharger, the brake booster, and a couple of large wiring harnesses. Using a flashlight and inspection mirror, I just don't see that rubber grommet for putting the wire through on the driver's side. I do have one on the passenger side near the battery, which I think is on all of the trucks, and was considering just going in through there and routing the wire behind the glove box / center console to the connection point on the fuse block.
  8. My AT4 has black A pillar panels. Here are the crew cab part numbers: 84588380 left 84588377 right https://www.gmpartsdirect.com/auto-parts/2020/gmc/sierra-1500/at4-trim/6-2l-v8-gas-engine/body-cat/interior-trim-cab-scat The extended cab shows different part numbers, but they are all on the linked page.
  9. No, it shouldn't matter about the fuel economy display for 25 or 50 miles. Are you filling up with the truck running? If it never shows full, I'd say it's time for a trip to the dealer for warranty work.
