I got the upper and lower organizers for the center console the other day. The upper one is pretty decent, maybe the lower one will grow on me. There was a discount if you bought more than one piece so it was only $10 more. They are very well made and fit really well. The bottom one wedges in place right at the bottom. The top one has four little notches that keep it in place on the rails in the console. The little rubber non skid matts in the upper tray are nice and grippy and have a diamond plate design that looks pretty cool.  They are made by Vehicle OCD on Amazon.  Nice to have some organization in there now.

I did this to my last truck and it was extremely time consuming and difficult. But I didn’t know what I was doing back then.  This time I taped around it and sprayed them on the truck. It was actually

How are you liking this kit? Thinking of having it installed soon.

If you don't mind, how much was it installed?

I really like this kit. Great ride, great look. I also like that it has the replacement UCA’s. They are stronger and longer than stock, keeping the geometry fairly close to stock as well.

I’ve been running this kit for about 7k miles now, and it’s been great. No CV boot wear or any other issues. I would definitely recommend it.

The kit is about $650-700 depending on where you get it. I installed it myself on my garage floor, so I don’t know what it would be with labor. It took me a good 6 hours, but much of that was trying to compress the strut springs in front. But a pro with a lift and wall-mounted strut compressor can probably do the install in about 4.5-5 hours to give you an idea.

Thanks.

Got it ordered up today. I don't feel like messing with the springs so I'm having the shop install.

$1100 out the door with the alignment. Tires I have won't work with the control arms though, so I swapped the tires and got some new wheels too.... can't wait to see the finished product.

Agree - you will love the look - ride is same as stock.

 

Tire Rack sells AT4 SST RL kit for $510 - free shipping - 4-5 hours install cost   Mine was right about $1,000 - with install - alignment at dealer after $200 so $1,200 all in - So Cal labor rates are not the best - $125 at good shops.

Your're going to have a great time!  Congrats.  Here's what I've done to my 2019 AT4

  • Bakflip MX4
  • 2 coats Ceramic Coating applied
  • Tinted front windows
  • Installed Opt7 Tailgate LED's
  • Blacked-out (plasti-dip) badges except for red "4's"
  • Installed 'Rapture" style grill lights
  • Installed 7” “shorty” antenna
  • Installed Multipro tailgate LEDs
  • GM Performance CIA
  • Installed GM Factory black exhaust tips
  • Borla S-Type Exhaust
  • Calipers painted red
  • Installed Nitto RG 35x11.5x20 (on stock wheels)
  • Installed Undercover SwingCase Truck Bed Storage Box

Did install the Nittos on the 20” GMC rims with no lift?  Did you have to do some cutting for fit?

I’ve been wanting the Undercover SwingCases but last I checked they didn’t fit the AT4 due to the multipro tailgate.  Did you order the standard Sierra model that says w/o multipro tailgate and install?

Nitto RG's are on stock 20x9 rims.  No lift beyond stock AT4 setup.  Only had minor rub in front of drivers side and only in reverse at full lock.  Zip tied the bracket behind the liner to the fender mounts and rub is gone.  No cutting needed in my case.

 

I only purchased the passenger side SwingCase so don't recall there being any distinction.  Maybe drivers side would be a problem because of assist handle.

I have decided to go with the rough country 4” suspension lift instead of the level kit.

also switched to 295/65 Nitto ridge grapplers and black rhino stadium 20x9 wheels.

and switched to the rbp stealth power step bars instead of the amp research ones.

 

planning on plasti dipping the front and back gmc emblems, the Sierra on the tailgate, all at4 emblems and the chrome exhaust tips.

 

i also plan on removing the valance.

Mind posting pics when you finish your plasti dip? Only thing that worries me about going with a lift is losing my ability to park in a garage.

will do.  i was worried about the garage as well.  my cousin has a ram truck that has a 6" lift and we measured his truck to the top of his room antenna and it was at 82"  i think my at 4 with a 4" lift will be roughly same height.  in which case most garages i think are 7 ft.   i only go to a garage at the airport or to Pelicans games at the arena.  the airport has a brand new garage and have huge clearances.  the superdome garage is old and low so i may have issues there. but i figured who cares this truck is going to look bad ass and i will just take my wifes car to the games...

Will these fit the consoles with the lock box?

      Tire psi

      By Chuck FB · Posted

      I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ).

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      Some Assembly is Required

      By Chuck FB · Posted

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
