Good question.   Following.  I want to get a front end level done on mine, but afraid it will not allow me to park in the garage at work.

I don't know the exact height, but the carwash I go through says 7'2" on the clearance bar and it doesn't hit. Mine is a 2020 HD Crew Cab Z71 with stock ride height.

I'm pretty sure the antenna on our trucks is just a tad higher than the shark fin. Grab a tape measure and measure from the ground to the tip of the antenna. that's the measurement you need

My problem is the garage door is 81 3/4" high to the weatherstrip/doorstop.  My '07 Dodge 3500 Quad 4x4 clears fine, but I see all the new trucks are at least a couple inches taller.  Looking at the GMC 3500HD 4x4 to replace it but have to know if it will fit!  Can't get an answer from the dealer as to whether the sharkfin is included in the cab height spec.  They say to take one home to try fit but of course there's nothing on the lot.

There was a thread just a few weeks ago on exactly this issue and a few of us posted measurements.

The shark fin is not more than 1/4 to 1/2 inch taller than the highest spot on the cab roof when the truck is unloaded. As you load the bed and the rear settles, the cab high point drops more than the shark fin, but the fin doesn’t move up. 
 

I have a GMC 3500hd SRW CCLB SLT gas with the 18 inch wheels and stock tires. Unloaded my truck is definitely slightly less than 80.5 inches tall in overall height including the shark fin. The 20 inch wheels and associated stock tires would make it about 1/2 inch taller.

Another JR:  Sounds like you have the same truck I'm looking at except I need a regular cab, long bed.  The spec on the GMC website is 80.67" for your truck.  So you think the height spec includes the sharkfin?  The reg cab, 8'bed, cab height is 80.94".

If that includes the sharkfin, I'd have a whole 3/4" clearance!  Lordy!  I guess one could order a truck without the satellite antenna to get a bit more clearance.  Sure would miss the Sirrius.  Also thinking I might pick up a bit of clearance with the driveway apron matching up to the garage floor at a slight angle, but can't tell without a test fit.

Thanks for the reply.

Yes I believe the shark fin is included in the overall height spec. Also, my truck is slightly below the height spec, but that may be because I measured with a full gas tank. The shark fin is mounted on the front driver’s corner of the roof, which is not the highest part of the roof on my crew cab (no sun roof). The high point is in the center about even with the back edge of the front doors. The shark fin tip is about the same height as the high point in the middle if the roof, not more than 1/4” taller from my measurements.  All of my measurements above have a little margin in them to cover any measurement error. 

 

From what you describe you should be ok and will have an inch plus of clearance.  You get used to it. My camper’s tallest vent clears my barn door opening by about an inch. You just drive dead slow every time to avoid any bounce.

On my 2500, the shark fin antenna pushes through the rubber weather gasket on the exterior of the garage door, just barely missing the wood. Talk about close, but it fits!

I found this in the chassis PDF file that I got when looking at the potential suspension issues on my truck:

 

Looks like there are some dimension for height but so many things can be different in real life. At least it gives a starting point.

      Brand new to this forum. Questions about re-gearing my 26’ HD

      By BDS my HD · Posted

      Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
