Do 37s Fit On A Stock Duramax?!

Installing 37x12.5s on my 2022 GMC 2500
Stock height
Stock wheels
No cutting

[@ezequielruelas5045]

Thanks for this video, im going 37’s with the stock wheels on my 3500 high country. Also doing a 3” leveling kit. So im for sure it will clear.

They look pretty good on a stock truck. I went with 35’s and they made a a huge difference on the curb appeal of my truck. Every time I fill up someone asked what all I had to do to get 35’s on it and I tell them they just fit. I did turn my torsion bars up exactly 4 turns to get the lower a arms off of the bump stop the week after I bought it. That actually improved the ride on rough roads quite significantly.

[@ericbenzel8676]

What is the exact size of your 35?

[@billylee2312]

@@ericbenzel8676 I have not measured them but the actual size is 35-12.50r20

[@charlesb4267]

That's surprising the bump stops were that close to bottoming out but admittedly I haven't looked under the newer trucks to see just how close the bump stop is to the A arm, had you by any chance added an aftermarket front bumper and winch to your truck that added more front end weight ?. Years back I had cranked up the torsion bars on a truck and the reason was to gain clearance and because of how far I went with the adjusters it caused the truck to ride stiffer which I was aware of being a side effect and also it really threw the alignment out which again I expected and had it realigned. Just curious if you had your alignment checked after the adjustment as it might not hurt to have that done, if its too far out that could cause wear on your expensive tires ... as you know how retarded tire prices are these days, certainly up in Canada where I am.

[@billylee2312]

@@charlesb4267 I did and it was dead on. I saw a KZbinr telling about the bump stops being so close and he ended up turning his 4 turns. I was skeptical but tried it and it was a improvement.

[@charlesb4267]

@@billylee2312 This is pure speculation but I wonder if the torsion bars experience an initial sag, leaf springs certainly settle in a bit with a little use. Even before the truck gets to its destinations its been either on rail or a vehicle hauler trailer and bound to be some suspension movement although not the same as driving down some of our Canadian pot hole and heaved roads for example. But good to hear you checked it out just to be sure its to spec rather than wish you had later.

Pretty tight in there! I got 35 12.50 R18 ,Nexen 12 ply Roadian mtx on my 21 DHD and they about perfect, wicked looks with a little more room, glad you got rid of the shit stock goodyear junk

[@domgarza5342]

Great & very helpful video. 👏 Thanks!

[@danielkwiatkowski4489]

I have the same truck but as a 3500. I did the same thing and only get the same rub as you at full crank. Does not bother me at all and the truck looks better. It's going to be a very rare occasion that you hit a bumb at full crank at high speed. Low speed no worries. She looks good!!!

[@Cruff16]

Exactly! If she don’t rub you didn’t go big enough

[@coltonritter800]

Looks good my man! it may rub a little but honestly you can cut some of that plastic out anyway.

[@Cruff16]

Thanks, I will do an updated video now that I’ve been driving it. But it’s just the sway bar that it rubs on. Way better than I thought

[@FX-cr7je]

Looks awesome! please let us know how everything is working after you get some time behind the wheel.

[@charlesbrazeau5923]

nice descriptive video buddy, thanks

[@greygrizzlyoutdoors1764]

Wheel spacers will fix all your rubbing inside, but then you will probably rub your bumper and likley have to do a norcal mod.

[@Cruff16]

I like the tucked wheels, no cut bumper for once, truck stays clean for more than a day. For how often and heavy I tow I am not a fan of wheel spacers. If I was someone who drove the truck and never towed maybe I would use spacers

[@p.youhana3563]

My work truck 22’ high country gas 37 no lift zero issue even when towing

[@Cruff16]

Yeah, mine tows great too

[@wilheimreis8272]

hit a big outdoor bump on a turn they might hit.i am in the market for a gmc,though

[@Cruff16]

I’ve put 40k on them and yet to hit the cab or bumper, I don’t off road with the truck but I work construction so uneven roads for sure with the truck

[@jasonbull4137]

Have you had any issues since doing this on the tires or truck ?

[@Cruff16]

Nothing at all, I have put about 35,000km on since and truck is doing great. The biggest factor is the front end geometry is factory, no additional stress on the front end components. If you crank the keys or level the truck then it adds stress and may cause pre-mature failure of the front end.

[@MilanPalushaj-uh3df]

Love it

[@wyattgardner3552]

Transamerica tire co had a recall on tires for vehicles over 10,000 gwvr. Predator, Venom power, and Transeagle brands. All made by Shandong Yinboa tyre. Risking a diesel denali is fine if you have good insurance. Risking your life isnt worth the price difference in a quality tire vs those cheapos.

[@truckingoover]

Wash 🧽 mitt Just saying

[@Cruff16]

Trust me, I miss having a clean truck, I am too cheap for a car wash and too busy to wash my hand every day. I used to live on a dirt road and the truck is on a job site every day.

[@jayspik6498]

You can just shim your front bumper 1\4 inch and you'll be fine

[@Cruff16]

Doesn’t rub the bumper, just the inner fender. A zip tie on each fixed it

[@bobwilson758]

Nice job ! There is a petrol product out that will really help under truck corrosion - It sprays on And I think you spray it every year or so - Not a undercoat stuff , it is just mostly clear and I Hear it really works nice . Not a big mess . Cool GMC truck !
