I am looking to upgrade my 2014 All Terrain to a new AT4, however I have one major potential problem....my garage door height

GMC website lists the total height of the truck at 78.2" however that doesn't take into consideration the different wheel and tire packages offered on the AT4.

Is there anyone with the 20" wheels that can provide the height of the truck to the tallest point on the roof???

 

Thanks

I have the 20's I'd say 78.2 is accurate. I got in my garage at work that has an 80" clearance with about an inch ½ to spare.

The height is the same regardless of the wheels because the overall diameter of the tires is very close to the same from the factory...

I have the AT4 with 20's. The height to get into my underground parking is 6'8" (81.6) and I have maybe 1" of clearance so I am guessing I am rocking 80.4.

 

Also depends on the tires you put on the rim, my sidewall is a little larger than most 20" tires.

wow...that's cutting it pretty thin.  Is 6'8" the absolute lowest ?  I know sometimes there are sprinkler heads and conduits, and other things that could get in the way.  I'd hate to drive under something and put a gouge on my new truck. ?

All depends on where you park. In my parking spot I am on the very first level and it is a receiving bay on the right and parking on the left so everything is rather tall. If you go down one level it is not as forgiving. Every parking location will be different.

Come on down..... 30 min to the mountains, ski resorts, Banff is 45 min away. It is beautiful this time of year.

AT4 with 20” rims comes with 33” tires, same truck with 18” rims (the ones with duratracs) run 32” tires.

 

So the trucks with the 18” rims are about half an inch shorter than the trucks with 20’s. It’s bizarre but true.
 

another fun fact. The spare is 31” OD Making it nearly useless. Not sure what kind of engineers GM hires, probably the ones with accounting degrees.

 

That is a pretty big difference imo.

      Transmission Temperature Hitting 220s

      Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      Future GMC Jimmy

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way too big headlights (similar to a previous non-Wrangler SUV) should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crossing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well
