Selling my 535i and getting a lifted truck. This is one of the best ones I’ve ever seen.

[@robthompson3560]

I’m extremely picky with impeccable taste in trucks😳. I just started searching for lift/tires/wheels combo before I buy an AT4. Don’t have to look anymore. That thing’s perfect!

[@rdavist51]

Your setup is perfect, even in the options you declined. Well done!

[@justinschnepf]

I second this. Perfect setup.

[@G8GTJav]

Yeah, 'til he adds more "poke". To each their own.

[@anthonycastillo1639]

Your truck might’ve been the deciding factor of what my next vehicle is. Bad ass truck man

[@TheTeeDay]

I got the slt in the same color and put it 2.5” in the front and 2” in the rear. Took the steps off too first thing. It’s a great truck. Traded my 3500 Denali in for it. It had 20k in equity....

[@englandboys5132]

Beautiful truck!! Wish I saw this sooner…. I had the leveling kit on mine without the new UCA’s and my entire wheel detached from the truck Friday. Broke the CV’s, UCA’s everything connected to the wheel.

[@markphilip581]

Sweet truck congrats bro. Love that grey mettalic .

[@GustavoTorres-pz3ep]

I agree with no sunroof options, it's a cleaner look. Great job on mods.

[@AlecksEats]

That’s clean! I have a black one, but with carbon pro and sun roof, I’ve never had a sun roof leak on any of my 20+ cars I’ve owned with sunroof. That’s my first time hearing anyone say they leak. The carbon Pro isn’t a gimmick but I get it’s not worth it to some to have it.

[@justinstrange1355]

Imo sunroofs used to leak back when they started coming out which gave them a bad name that's been hard to shake. With new technology i would guess there's a very low percentage of leaking. Badass truck! I'm looking at it in either black or white. I just wish they didn't do the orange accents on the seats. It doesn't match anything

[@AlecksEats]

@@justinstrange1355 dude! I agree! The brown leather is what makes it short of perfect. If it was all black like the Denali and had a 10” screen it’d be perfect. I still love it though. It’s an amazing truck, fun to drive and comfy. Looks amazing too. Black is the best looking IMO but it’s hard to keep clean. Make sure to you ceramic coat it. It helps! I agree on the sunroof comments.

[@whosonfirst7610]

Nothing but love for this truck!

Thanks man!

Hi Nathan! Awesome job! Can you please share what RC Level kit model you ordered? I am having a hard time finding 2". All i am finding is 1.75. Thanks!

[@christopher4091]

Truck looks awesome, blacked out exhaust tips would have an extra nice touch!

[@davidyokley8441]

You verbally said 295 70 17 on the tires/wheels but list them as 18's. Which is it? Did you calibrate the speedo for the new tire sizes? Just wondering if your gas mileage is accurate, or not.

[@adriancardona4202]

I just got my at4 3.0 last week and this right here is perfect! I definitely need that tint and ceramic but badass truck you have I love it 🔥

[@alonsorocha3567]

Badass truck bro! Just got my 2021, leveling it with the upper control arms because of your recommendation!

[@zobernuts]

Congrats bro! how do you like it?

[@ChrisDIYerOklahoma]

Looks really solid! Nice job. I got a 2021 GMC Sierra AT4 (6.2L). Currently have excellent running 275/70 R18 Bridgestone Dueler A/T Revo3. At the time, I didn't know they made 295/70 R18 (about an inch taller). Love these tires...Load E range, A/T, quiet, mildly aggressive vs others. No highway groan.

[@21AirDrop]

Would you mind letting my know the lift you chose and how high? Leveling kit? Any lessons learned since you’ve modded your truck?

[@ChrisDIYerOklahoma]

@@21AirDrop Glad to give you some insight. I didn't do a lift. All I did (front) was swap out front struts. The Ranchos suck (IMHO), I went with Bilstein 5100 front adjustable struts with 1.75" added front height. So, leveled the front (or really close). I also put 5100's shocks in the back. The ride is firmer and 10x more controlled. When you do struts up front, get an alignment and have all the bolts retorqued after 1,000 miles (any mechanic will tell you that). I had a clunk noise from the front when articulating the truck while steering...nothing significant...just a clunk now and then. I took it to a different shop...they retorqued everything and the problem never came back. The truck will do 95 mph STRAIGHT down the road with NO vibration or drift. It rides BETTER than new now esp with the Bridgestones. Go over to my KZbin channel and I got pictures/discussion: kzbin.info/aero/PLzPyOyIC4NzjbWOm8gpZaEVw39t9cOKm5

[@jeffcurtis1742]

what is the offset of the new wheels? how did the 1.5” spacer’s work out?

[@pksfirepit7212]

Love your truck, I am looking to add same wheels and tires, but I noticed in the video you say 295 x 70 x 17 Nito Ridge Grapplers with 18 x 9 -12 Offset Method NV 305s; is that correct?

[@Wankelpunk]

Truck still feel quick with those wheels and tires? Tow at all?

[@jaisonbrown1907]

Compared to an 2021 elevation, would you have a total lift of 4 inches in the front and 2 inches in the rear?

[@Fahrenheit_Motorsports]

Just wanted to confirm if you put a 2” level on the front and rear? Or only front? Thanks

[@B_WillGoPro]

FIRE 🔥🔥🔥

[@alecbaye9703]

Wow 27 mpg highway that’s amazing

[@trouthunter22]

Great looking truck. Agree on sunroof and steps. De-badge and tint are nice! I’m waiting for 2022 version and to see if GM solves the long crank issue. Did you consider the 285/70/18 ridge grapplers? Still 34” (33.98 vs your 34.29), .22” narrower, with slightly less load capacity but 9.5lbs lighter each. Love the method wheels. Always takes some experimentation to find the right offset and tire size that minimizes trimming and meets all your other requirements. I think the poke is perfect. I’m going to add a Diamondback bed cover, bed slide, Dometic fridge/freezer to the bed. Probably do a 2.5-3.0 suspension lift with king shocks and Icon upper control arms. Not sure what I’ll do for rear springs. I’ll see how much weight I end up adding. Cheers

[@ElectricBlueIX]

His tire is a 295/70/17 which comes out to 33.31 per Nitto’s site. That’s a little surprising there is any rub at all with a 33” tire when the front is leveled with the rear. This is essentially a 3.5” lift on a standard Sierra/non AT4.

[@brolandry]

@@ElectricBlueIX his tires are 295/70/18. look at 2:35 on the video. He may have just misspoke when he said 17's

[@luimurillo-sotelo430]

Do you have a video on how you took the front license plate off ???😭

[@samcrews3407]

Absolutely PERFECT.

[@4Cabin]

Looks really good. Not over done on the lift or wheels/tires. And yes, correct, you cannot level up the AT4/Trail Boss without new UCAs. Guys are doing it anyway and regret it later for going on the cheap.

[@ervinflores9825]

Love your truck. Bought my 1st truck an 18 Tacoma but I can’t lie I wanted a dirtymax gmc

Very nice looking rig brother. I have a 2021 Chevy RST

Great video and narration but Tires appear optimized for OFFROAD, what if you go 80% Hwy and 20% of that is RAIN? What tire swap you do? Same rims?

[@azpacfan]

Looks sick. Just got mine, gotta tint it first. Did you mention what level kit you installed?

[@ragredo]

Great looking truck! good job! ......I just got my At4 and I like your set up. Did you get a 2" Rc lever on top of the 2" stock lift from GMC? so technically the truck is lifted 4" ?

Hey, sweet truck! I have the exact truck in white. I have a question? I am running the same tire, 295,60r20 in ridge grappler 34inch, I am having an issue where when I switch lanes on the highway and there are groves in the middle of the lanes my truck catches them and feels like I have a ton of body roll. Wondering if that's the way it is or I am having issues with something else. I do have a level kit with upper control arms from ready lift. I think the issue is either with tires or the rancho shocks, your input would be great! I have the Hellwig front and rear swaybar on order and Beilstein front coil lower and rear shocks to hopefully remedy the issue. Other than that best truck ever! My last truck was 19 raptor fun but useless for a daily truck, this one hits all the marks. I also average 26-27 in highway and 21 city. One thing I did add was the s&b air intake. Helps with mpg I have a heavy foot and gain back 1mpg per after install.
