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.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      2027 GMC Sierra: Official Discussion

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.

      from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.
