  1. I bought the 3 piece Underbody Shield (Part No. 23176882) a few weeks ago and had all 3 pieces powder-coated a matte red color that would match the red in the GMC emblem.. Fast forward to trying to install them last week and 2 of the 3 fit no problem, however the 3rd (which is the largest & most prominent one visually) did not appear to fit. The back bolt locations line up perfectly where it meets the other plate, however the front piece looks like it isn't long enough or shaped/angled correctly to reach what appeared to be the obvious locations for the provided threaded bolts. This Part No. as a standalone is 23135960 (GM OEM Engine Skid Plate). My question is this: Does this item actually not fit? I understand the Denali trim level has a different lower bumper due to the LED fogs, but did GM seriously over-engineer this to the point that the internals/bolt patterns & cross members don't match up for these?!? Hoping someone can provide me some input of confirm I'm just being an idiot & that there is a way to make this fit, because I really want to get this installed or find the proper replacement ASAP..
  2. Good Afternoon fellow 6.2L enthusiasts. I apologize if this sounds like a commercial or a rant. I just like to share what I've experienced and discovered. So, I don't know about you, but I've been searching for a way to cram more air into my L86 that won't break the bank. I've done hours upon hours looking for the perfect bolt on's or practices that will help the block breath deeper. I've learned that swapping intake manifolds are not worth it however, porting makes it one bad ass manifold. (which i've done) I threw on an AFE CAI and that really helped get the air moving. (momentum GT pro 5R) Headers and a bigger full exhaust helps get the flow rolling. (I'm rocking TSP 1 7/8 Headers with a 3.5" full exhaust (catted with Cal Cats) and a Flowmaster Pro series Muffler) Cylinder Heads and a Cam shaft will transform your truck. (going with TSP Heads and a Trick Performance Cam package) And a basic tune wakes these bad boys up. (local dyno-tuner) That being said after the above you're looking anywhere between 430-530 HP N/A. Obviously the Cam specs are going to swing that number. Now, The one thing that I have NOT been able to find is a Larger Throttle body that will fit the L86 Stock Manifold. So I did what most have done and ported that sucker out. The only issue is it will never be larger than 87mm. Until this came along. https://www.bbkperformance.com/92mm-throttle-body-14-18-corvette-camaro-lt1.html FYI slight modification is required to the stock Manifold. You need to shave the base of the Vacuum port as well as the MAP sensor base for the frame to fit. Once that is done you're rocking. I was able to Port match the TB Bore to the manifold inlet and smooth out the transition. Honestly I can immediately feel the difference. When I get a little bandwidth I will throw on some videos of Cold/warm starts, take offs etc. If you have any questions feel free to reach out!
  3. Thought I'd post a review of the newly installed suspension and wheel set up on my 2016 GMC Sierra Denali 1500. Previous set up was stock MagneRide suspension with ride height sensors and 22" stock wheels with Nitto Terra Grappler G2's size 285/45r22. I'm at 70k miles and the ride was steadily getting worse (too stiff), so I researched for a while and ended up installing the following: HaloLifts Boss Ultimate Kit (adjustable coilovers for 1" to 3" of lift in front, and 1" of lift in the rear) - http://www.halolifts.com/HaloLifts-Boss-Ultimate-Kit-fits-your-2007-UP-GM-SilveradoSierra-1500_p_220.html Stock GMC Sierra 18" rims (powder coated black) with Falken Wildpeak AT3W's size 275/70r18 Bypass sensor kit for all 4 MagneRide shock sensors and all 4 ride height sensors (I removed all ride height sensors that are mounted to the frame) - http://www.xineering.com/shocksims.html Up first, the HaloLifts Boss Ultimate Kit At $1299, this is a more expensive kit vs the Fox, Bilstein, or Rancho equivalant. What swayed me to this kit was that I was not looking for a crazy lift and I wanted something that was plug and play should I go a different route once these start to fail (like all shocks eventually do). Additionally, I found multiple reviews on this forum and other brand forums where people said they had installed Fox, Bilstein, and/or other brands and this was the best riding kit and worth the extra cash. You'll find a rep from the company, Alex, who's posted in this forum, as well as others, and he says call him with any questions. I did, and he answered every time and would not let me go until I had EVERY question answered. The customer service is outstanding with this place. I ended up going with the coilovers set at 1.5" of lift and I put .5" spacers beneath it to get 2" of total lift and the softest ride possible. Each kit is made custom to what you want, so that's how it arrived for me. You can have the coilovers set at 2" if you want, then add 1" of spacers underneath. Since I am only doing 2" of lift, I did not purchase new UCA's. Below are pics of me opening the packages. Again, thoroughly impressed with how sealed everything was with plenty of foam and cardboard to protect everything. Install was a breeze, thanks to instructions that were included and my convo with him over the phone. One last thing, the "do the rear shock boots go down or up?" debate has been settled. According to HaloLifts they go down :-) Next, the new wheel/tire set up I downsized from a 22" set up to an 18" set up so I could get more sidewall and a softer ride. While I like the look of a larger rim, it was so easy to get scratches on the 22" rims since they are so close to the ground and there's not enough sidewall on the tire to bulge out a little bit to help protect the rims. So, new set up gets me a softer ride and better rim protection. I went with a stock rim and had it powder coated black because I've had mixed experience with aftermarket rims (good and bad). As far as the tire choice, Falken Wildpeaks kept coming up as best all around value for it's performance. I've had KO2's in the past, as well as other AT tires but I wasn't blown away by their performance for how much you spend on them. Falken's were cheaper, but hold up well in rain, snow, and mud. Plus they have an aggressive look, that's a nice bonus. Below are pics of the truck with the new wheel and suspension set up. I'll follow that up with the obligatory, "pardon the dirty truck, haven't had time to wash it". Last, the MagneRide bypass kit This only applies to those who have the MagneRide suspension and ride height sensors (certain trims like Denali). If you do have it, you'll need to bypass the sensors or you'll forever be dismissing a message that says "service suspension system". If you can live with that, then ignore all of this. If it'll drive you nuts, you have 2 options - one cheap, but could lead to other issues and the other is not so cheap, but will not have issues. There are 8 sensors total, 4 shock sensors and 4 ride height sensors. The first option is to go cheap and buy 8 resistors (3 ohm, 25 watts). You then splice them in at every sensor. The risk here is corrosion, if you don't seal the splices properly this leads to the wire harnesses going bad and having to purchase all new harnesses and resistors to do all of the work again (and now you've spent more money on the harnesses). In all, this could run you about $50 for resistors, heat shrink, and a heat gun. The second option is to do what I did and buy the professional bypass kit from x-ineering. It's $425, but they'll give you a $75 discount if you post about your install on social media. I went this route because they clip in and seal the wiring, just like the stock sensors. No risk of corrosion and everything they make is backed by warranty. Overall, I'm super happy and love the ride. Only a couple hundred miles on it so far, I'll report back after all my Thanksgiving travel coming up (1500+ miles). Let me know if there are any questions!
  4. I have a 2018 GMC Sierra 1500 Denali. I just installed the 2” Rough Country front leveling kit. I couldn’t do the 2.5” because my truck has the stamped control arms. The rear of my truck still has about a 1.5” lift/rake compared to the front that I am sure is caused by the rear lift blocks since it is 4WD. Can I remove the rear blocks safely? Or will it cause any damage to my Magneride suspension? What are my options to lower the rear to match the front of my truck now?
  5. Zane Merva Executive Editor / Publisher, GM-Trucks.com November 30th, 2018 Only days after we got a more detailed look at the 2020 Chevy Silverado HD and the 2020 GMC Sierra Denali HD, the Sierra HD is out in full public view once again. This ramp up of public testing can only mean one thing. We're close to the all new 2020 HD's being unveiled. Look out for the new HD duo to go public soon and officially debut in January at the Detroit Auto Show.

  6. Zane & Josh Merva GM-Trucks.com March 12th - 16th, 2018 As attention starts to shift from the current generation of K2XX based Silverado and Sierra to the all new 2019 T1XX based trucks, it's all too easy to forget just how far we've come and how much General Motors has "perfected" these tools over their last generation. Case in point, the 2018 GMC Sierra Denali. It's the company's most luxurious pickup ever. (Well, at least for a few more months). When the opportunity to take this generation Sierra for one last spin presented itself we jumped at the chance. A week behind the wheel of a 2018 right before the 2019 models started to hit the ground sounded like a perfect refresher. Each day this week we'll share our time, photos, and thoughts about this range topping model. Being that it's a Denali, it has... well.. everything. From the high-powered 6.2L V8 to the rail-like magnetic ride control and the plush heated/ventilated seats, this Denali has all the goodies to compete with pure luxury sedans from the likes of BMW, Lexus, and Audi. Stay tuned all this week as we add our thoughts and a slew of images to this thread. The Truck We're Reviewing 2018 GMC Sierra Denali 1500 Crew Cab Starting Price: $55,755 Total Options: $8,045 Destination: $1,250 Discount: -$750 Total Vehicle Price: $64,345 The Window Sticker First Photos Master Review Photo Gallery
  7. I just bought a 14 sierra denali a few weeks ago, I assumed it had the magneride suspension but looking at the struts I believe it's just the standard suspension. I did some reading and it sounds GM didn't introduce the magneride until the 2015 model on the denali, is this correct? There's nothing on the original window sticker that says anything about the magneride, honestly I'm hoping it's just the standard suspension as I plan to lift the truck and there's not a lot of options with the magnetic ride.
  8. SOLD $375 now $300 (PayPal Friends and Family) Shipped Insured to White Automotive and Media Services I am selling this 2018 Sierra Denali Diesel UHS cluster that I purchased off of ebay as "New - Other". The listing had it listed as a 2017 UHS cluster but what arrived was a 2018 UHS Cluster, P/N: 84385169. WAMS was nice enough to attempt to program it for me even though it was for a different model year but they were unsuccessful to make it function 100% with the vehicle due to the MY difference. This is for MY 2018 Diesels and is US Spec (MPH). I will ship the cluster directly to WAMS once I have received payment AND your Order # from WAMS. I will send you the tracking information once it ships. WAMS's website is listed below to assist you with purchasing their programming: http://www.whiteautoandmedia.com/ This requires special programming before installing in a vehicle. I will ship directly to WAMS to ensure that the required programming is done correctly so there are no tamper flags or anything tripped as there would be if it was installed prior to programming. I am just trying to recoup some of my loss. I have attached pics of the actual cluster. If you have any questions, please feel free to message me.
  9. I recently bought a used 2016 Sierra Denali 5.3L 4x4 in March with 48k miles. Truck has been great until yesterday (now 52k miles) when I ease into the gas it shudders and shakes like crazy until i punch it. The tach is bouncing up and down and it doesn't matter if it's in v8 or v4. It almost feels like it's a misfire but it's weird that it only does it when I'm easing into the throttle or going uphill. The truck has the 8 speed transmission. Has anyone else ran into something like this and would the manufacturer warranty cover the fix for this?
  10. Ok, something just started happening with our 2016 GMC 2500HD Denali 4x4 with the diesel. The remote door lock and unlock won't work every time from either of our fobs. We bought this truck last August so I can't imagine the batteries in both of our fobs have died at the exact same time and only 7 months in. My fob gets used the most with my wife's fob barely getting used at all. Anyone else experience/experiencing this? And, what did you do to remedy it? I guess we can try replacing batteries first, but batteries only lasting 7 months in a fob? And both failing at the same time, especially given one gets frequent use and one barely gets any use. We know it's not a fuse because it does work from time to time.
  11. Hey guys, like the title says, is the 16/17 GMC Sierra 1500 grilles easy like the silverado ones now or are they still harder and you need to take off bumper pad etc.. I wanna color match my shell and am wondering how hard it is before I get too involved. I searched the forum and lots of info on 2014 and 2015 but couldn't find any for 16/17. Thanks for any help guys.
  12. OK, I come from a GM family and have owned many GM vehicles. I just bought a GMC Sierra 1500 Crew STL2 over a Denali in January. Now I like chrome but does anyone else think GMC goes overboard on the Denali chrome grills in their vehicles? I feel like they are just trying to out chrome everyone else. It's almost like, "hey, look at all this chrome. I'm a Denali. I'm expensive!" I may be biased but personally believe the STL grill is more subtle and stylish. My STL has the premium package with most of the same options as a Denali as well.
  13. I have a 2002 Yukon XL Denali, and the button on the lift gate to open the window won't go in when I press on it. Which key do I put in there anyway? How do I open it?
  14. Where can I find this Denali 2500HD Hood Scoop?

  16. I now have about 1 k miles on my 19 SD pickup. Some things that I’m not happy with- I know some are nit picky. I hate the auto start/stop. And I’m sick of hitting the button every time. Anyone have a work around yet? A fuse pull or something simple? If I wanted gas mileage I’d have bought something else. The radio- why is the color different for the artist and song? The station shows up white, but the artist and song color is so close to the lousy boring background color that it’s hard to see. For some reason, my iPhone 8 lowers its own volume every time I get in the truck. Weird. Why doesn’t the HUD display the radio station when switching? My car does. Am I missing something? Not a big fan of the dash gauges. My 17 was much nicer. Overall I like the truck. Gas mileage is not as good as my last one however. We will see if that improves. Any responses will be appreciated!
  17. I'm in search of a set of gm tri-mode running boards and computer that comes on the Sierra Denali or Silverado High Country. I'm located in Houston TX.
  18. I just bought my 2019 Sierra Denali with the 6.2 and the 10 speed auto 😀 has good power just wondering about a tune especially which should wake this bad boy up if anyone has the new Silverado/Denali let me no what y’all think 🤷🏼‍♂️
  19. Hey Guys, New to the forum, and glad to be finally back into a truck after a few years. So I just recently purchased a used 2015 denali 6.2 with 55k miles, and the previous owner installed a leveling kit. Now the problem is that they did not install a relocation bracket for the magneride sensor. I noticed that it seemed to ride rougher than my dads non denali and so I started doing more research on here and other places. I had heard that if you didn't want to go the bracket route, you could have the dealer reset the shocks to zero in the computer so the truck knows its level. Since I had just bought it a little over two weeks ago, I figured I would just take it back to the dealer and make them do it. When I got there and meet with the suspension guy, he said hes done over 100 leveling kits, and hes's never had to put a bracket in there. So he said he wanted to check the shocks to see if they were ok, and once he got it up on the lift, he then noticed that they were leaking and would need to be replaced. He drove it and agreed that the ride was really stiff and said with the new shocks the ride should be 20x's better than before. Since I didnt have to pay for anything I said absolutely, go ahead and replace the front struts. Long story short, got the truck back, and yes the ride is definitely better, but it still feels fairly stiff. So I was hoping that if someone on here had the brackets on their's they could hook me up with some dimensions and I could just make some of my own. I called suspension maxx, but they told me they could only sell me the brackets if I had some sort of proof of purchase, but of course I don't because the previous owner is the one who purchased it. I appreciate any help or advice in advanced. Thanks, Adam
  20. Can you guys offer any suggestions or tips before I go to stealership? '16 Sierra Denali, 40,100 miles. I bought it 3 weeks ago with 39,800. Randomly displays 'service theft deterrent system' and I cant start. Dash lights up etc, but cant start. Have had to use oem remote-start as a work-around, but that isnt working now either. The engine will start but as soon as i put the key in, turn to 'on', and put in gear, engine kills. Battery is original, but good. Reading 12.6v engine off, 14.1v running, and load test is good. It seems to happen more when stoping/starting over short periods, like starting 1st in morning fine, go to get gas, turn off 5 min, wont start. Get it startedz drive and stop at ATM. Turn it off 2 minz wont start. If it matters my Infotainment outside temp is never correct either - and i mean off by a lot. Any ideas or suggestions? Thanks guys! PS - did new sierras come with 2 keys AND fobs? Dealer gave me 1 key and fob, and 2nd key by itself. Said GMC only gave 1 fob (and 2 keys) to new purchases.
  21. Taken from a 2017 GMC Sierra Denali Ultimate - - 22" GM CK164 Wheels and tires package for sale. 4 wheels, 22x9 aluminum + 4 tires + 4 TPMS sensors installed + 4 tires mounted + 4 center caps TPMS sensors and Lug Nuts INCLUDED OEM wheel part number 19301164 7-spoke silver with black inserts and they retail about $500 each. 285/45R22 Brigestone Dueler A/T RH-S tires have 30K on them but they definitely still have some life left in them - I don't have a tire tread gauge or I could tell you the exact depth. All parts listed here are OEM Factory parts unlike the cheap knock-off replicas you find on the internet. Located in Columbia, Missouri. $1800 OBO EDIT: I would consider shipping them if buyer pays for shipping, up front and payment clears. I did a quote through Greyhound Package Express and it is roughly $400 to ship them to the lower 48 states, give or take depending on your location. If you choose this option, you will have to be patient with me shipping them as I will have to drive 2 hours each way to get to a Greyhound shipping location.
  22. About an hour into my two hour drive tonight I noticed the lane keep assist button was no longer illuminated so i pressed it and got the message "lane keep assist system unavailable." I tried cleaning in front of the camera behind the rearview mirror and turning the truck off and back on. I could not get it to work. I am new to this forum and was hoping someone would have some advice on what to do. This is a 2016 sierra denali 1500 with approx 50k miles so of course it is out of warranty.
  23. 2017 GMC 3500HD Denali I pulled a bonehead move this afternoon. As I backed into my driveway, I waved back to a neighbor and backed into my trailer. The trailer tongue damaged the plastic step and bent in the socket for the spare tire. I'm reasonably sure I can fix the bend near the spare tire socket, but need to remove the plastic bumper step piece in the process. Anyone know how the step is removed? (are there any gotchas or hidden clips to snap, etc) And where I can source a replacement (as it's now got some ugly marks on it)?
  24. Hi All, A newbie here in So Cal. After 30 + years on the job decided to pull the plug and retire. I've had a company car for the past 20 years so I had to find me a nice retirement vehicle. My retirement truck is a 2018 Sierra Denali 4x4 with the ultimate package. After 3 months I love the truck. I only have a couple of questions and looking for some advice. 1: Is it normal for the transmission to clunk at times and shift hard? 2: Can the Denali be used off road and is it possible to change the 22" wheels and tires for 18"? If so will it void any warranties and or mess with the suspension? Once a year I travel to the Eastern Sierra's for a week of trout fishing. There are some places we go that is off road etc. The truck is soooo nice I almost don't even want to take it off road but if I do will I have to worry about what it can or cannot do? I know I should have gotten the All-Terrain but my dealer said it was to late to order as they had already started gearing up for the new 2019's. Plus I couldn't find one I liked that could be dealer swapped. Thanks a head of time for your answers/recommendations, Dj
  25. Compared to my wife's 2015 Denali is pretty bad. I know they go with the lowest bidder. But even Dollar General has it's standards. What's with all this smoke at start up? What's with this gay blue dash that's not rgb or some other color. The back up camera looks like 480x600. Think I'll drive my E99 Powerstroke a lot longer.
