  2. Hey guys, I finished up my install video of the DuraFlap mudflaps on my GMC Sierra. I had these same flaps on my last truck for when I was towing jetskis and absolutely loved the look and functionality of them. The flap kits ran me about $90 for the front and $95 for the rear for my GMC. These look a bit more utilitarian so if you value form more than function these likely aren't your cup of tea. I bought the kits without the weights (straight plastic) but you can get them with stainless and powder coated weights to prevent sailing. MY past experience says sailing isn't an issue even with the unweighted flaps. Link to all the designs you can get: DuraFlap Mudflap Gallery Front model numbers: GF2 14 1500 Rear model numbers: GR2X 14 1500 Overall very happy with them. One of the issues I was having with my previous mudflaps is they were basically ice/slush collection areas; combine that with parking outside in the winter and I had some icy mornings. No longer an issue with these gigantic flaps. Enjoy! Front: Rears:
  3. Hello all, need some help on ordering a part for my 2006 GMC Yukon Denali XL. Installed a JVC aftermarket radio, completed buy a certified audio technician. Install went great but he told me that my amp was bad volume would not be sufficient. Cost to bypass amp and install aftermarket amp and labor is $445. I see that replacement is pretty easy, just do not want to rip off my dash and console to the amp just yet to see the part number. Can someone please tell me what the exact part number is for my baby ? 2006 GMC Yukon Denali XL Bose audio system. Has back seat DVD Entertainment System.
  4. BrandonPrasad's 2017 GMC Sierra 1500

    So here is my build, I have a 2017 GMC Sierra 1500 SLE Z71 Crew Cab Elevation Edition Summit White 5.3 L Flex, purchased on March of 2017, I didn't know what I really wanted to do with it so I started out with a 2.5" Levelling Kit, changed out the stock tires with some 305/55/R20 BF Goodrich All Terrain KO2's and some 20x9 Fuel Nutz Rims with a offset of +12. There is a slight rub at full turn. I then ordered a RanchHand Grille Guard which came out to approximately 1000-1300 CAD from the GM Dealership, and the next day rain guards and a bug deflector which costed $180 CAD from the dealership. My next purchase then followed with a Mictuning 60" LED Tailgate Strip Light which came out to $40.00 CAD on Amazon, then the 2017 GMC Sierra 1500 Tube Led Tail Light Black Housing Clear Lens Upgrade off of eBay which was 288.91 CAD. I also changed out all my exterior bulbs with LED Bulbs (Such as the plate light bulbs, turn signal bulbs, and reverse bulbs). The 50" curved led light bar that is mounted on my roof is the AuxBeam 5D Projector Lens 288W Light Bar which cost $189 CAD and the one on my grille guard is a 40" Auxbeam Cree Flood/Spot Combo which was $131 CAD. The rear third brake light was the most pain to install, I paid $100 CAD off of eBay, had to reseal the weather stripping all around it, and both screw holes cracked when installing so I coated it with LePage Glue and it sealed nicely.

  7. Good day, I have a chevy silverado 1500/2015 (with stereo with small screen) and a few months ago I made the purchase of a larger stereo but it turns out that the stereo is a GMC sierra (turns on the button in red). When installing it turns out that only the buttons work (raise / lower the song change volume) but the screen never turns on. I do not know what the problem may be, I do not know if someone knows something about the issue or that a problem similar to these has already been solved.

  9. Part number needed. Help 😊

    Hello all, need a little assistance in finding a part for my truck. I went to install the radio that I purchased aftermarket of course, and found the wiring for the radio with no power from the A1 wire. I do not think it is the body control module so I'm going to try and replace the wires first. 2006 GMC Yukon Denali XL I need the part numbers to the wiring harness that runs from the radio to the BCM. Your help is greatly appreciate it and thank you for taking the time to answer my question!
  10. Howdy, I have a 1998 Silverado 1500 with a 350. I bought the truck for parts but I might decide to fix it. The truck runs however water seems to dump out from underneath the AC compressor. The cooling system doesn't stay pressurized and the water comes out as fast as I can put it in. There's no coolant in the oil and it doesn't seem to burn any either. So I'm leaning towards it not being a headgasket. Any other ideas?
  11. Anyone else with a new 2014 Sierra having an issue with the frame rusting and paint/wax flaking off? I have 3000 kms and it looks horrible. I also own a 2011 Canyon service truck with 105kms and the frame looks like new. So irriating as my Sierra is a beautiful truck aside
  12. Hey. So i have a 2014 gmc 1500. I put cold air intake on it and had it tuned time for new exhaust. But not sure if i want to go with headers and highflow cats and some flow masters. Or if i should save a few bucks and just do cat back exhaust 1 in two out . Yes def sounds better with headers. But. Im wanting some hp too. Is the gains gonna be worth the money to run true duel with headers. Or will jist cat back open it up enough. Any feed back would be great thanks.
  13. 2017 sierra A/T crew cab I have the most annoying tick noise over bumps, coming from the b pillar behind my left ear and it is driving me brick house, I've pulled at the trim off put my hands on everything made sure everything is tight, stuff rags in between contact points, I've run out of ideas, anyone have an guidance for me, I'm a ex gm technician of 5 years , I know what I'm doing but of course my own truck baffles me..per usual any new bulletins or tsbs?
  14. Engine mount leak

    I need help figuring this one out, I just bought this Yukon XL (100k) and drove it home (about two hours of driving) and I had a fluid puddle on my driveway the next day. So I checked it out and the only spot where I could find any “leakage” was from the drivers side motor mount. There were no other apparent fluid leaks or spills from anywhere else. I took it in to have it looked and and the liquid had dried and only left minor stains. He thought I was crazy at this point. I asked the tech if he could check the parts listing to see if it was fluid filled. He came back with a engine mount checklist which states to check for fluid leaks from the mount if equipped with GLYCOL(i.e. coolant) but also said he doesn’t see any signs of a leak even after I showed him pictures and he pulled up the inspection checklist. I need proof that the mount needs replaced because the fluid has leaked out. GLYCOL dries to show very little sign of leakage. How much fluid could he expect the mount to hold to keep leaking? How can I know for sure that this mount is the fluid filled kind or not? I took pictures of all of this.
  15. Zane Merva Executive Editor / Publisher, GM-Trucks.com 11/7/2017 Only a few short days after capturing our first look at the 2019 Chevrolet Silverado without cladding for the first time, our unflagging spy photographer has done it again. This time however, the Silverado's next gen twin, a 2019 GMC Sierra got the once over. Just like the Silverado, the T1XX Sierra has shed all of it's body-disguising cladding for a more visually revealing "camo-only" set of clothes. Check out our T1XX / 2019 Chevrolet Silverado & GMC Sierra Discussion Forum Our photographer reports:
  16. so I went in order of torque spec by doing 22 ft lbs on exhaust and intake valves of coarse on 2,4,6,and 8. I would torque intake rocker arms when I had exhaust valve just starting to open and exhaust valves when intake valves were just starting to close. this was done with the engine under the hood, wiring all in tact, ect, ect... Now... after doing this torque spec than firing the truck and ran rough as hell until I back off the bolts, than everything sound fine after that. I than proceeded to snug the bolts back up gently before putting the valve cover back up. No tick no nothing. test drove it about half a mile. loud as hell tick and misfire coming from cylinder two. where is the middle ground here because 22 ft lbs seems to be too much and getting it snugged up enough to where it sounds normal at idle doesn't seem to cut it either. Please I need help.
  17. I’m looking for ‘16 or ‘17 Denali Headlights . Anybody got any for sale ?
  18. Well, seeing as how I can't find much on this subject no matter what forum I go to, why not try to start the discussion here and see what kind of following I can get and see where we end up. If you're reading this thread, chances are you have thought about modifying or swapping out your current transmission in your 2014+ GM truck. In my case, I don't mind my 6L80 in my truck. It does fine for what I do right now and it's holding up just fine, but I think the big issue is when you start to search for big power (like I'm starting to do), that 6L80 is not going to hold very much (or so we think). Now, let's all face it. We've seen posts after posts, comments after comments, photos, videos, etc. of guys with built motors with turbos or prochargers shooting down the quarter mile in search for the best time on these 6L80s. Some say they're completely stock, others have them built, and we all ask ourselves the same question: Reliability. How well are these transmissions going to hold up to the abuse on the track? Especially if you want to make it a fast street/strip truck and drive it back home to the garage afterwords. We know for a fact that 6L90s can hold quite a bit of power. Even though I've mostly seen it in Camaro ZL1 applications, there is a guy on YouTube (GuitarmaggedonZL1) who is running a stock 6L90 on stock converter making 1000HP (give or take on an unloaded dyno) and the transmission hasn't puked all over the ground just yet. (Exaggeration, I know.) So, needless to say, a 6L90 swap sounds nice, at first... After you figure the extra length and weight (and in my case, relocation of the transfer case and getting custom driveshafts made), it starts to look a bit unpromising, but still not out of the ball park yet since it will be able to handle the power some are seeking, but where these newer transmissions lack significantly if you want to do boosted applications at the track (or even just launch control on N/A), no one has developed a transbrake. Very, very few forums are talking about this, and only one video exists of a guy in his BMW testing out a transbrake on a 6L80/6L90, and who knows how reliable it is. So, now, you start to think: Well, gee. What can I do now? How about a TH400 or 4L80e swap? So far, I've seen few posts on that as well. No one is talking about it, and I think the biggest problem people seem to be facing is the new PCM: E92. Also possibly the fact that the TCM on the newer transmissions is inside the transmission and whatnot, but whether that plays a part in this, I don't know yet. Now, adapting a TH400 or 4L80e can be done (most likely with a different bellhousing since the bolt holes are in a slightly different spot), but you run into the issue of getting it to speak/cooperate/communicate with the new E92, which I don't think anyone has tried. The only video I've seen of anything working in this application was on a 1320Videos video with a Nova where they were using an LT4 long block (built motor to 388 C.I.) and twin turbos, and it had a powerglide in it. Don't know if it was a manual valve body or computer-controlled, but what I do know is that they used the factory computer to run the DI injection system and piggybacked the rest to an MS3 Pro. After dealing with some issues, they were able to make that thing boogy to a 9 second pass at 148mph. So, these engines have potential to haul ass, but we just haven't figured out how to crack the system. So, at this point, I'll just leave what I've discussed here and see where the thread goes from here, and I'm hoping people chime in and vendors are watching/listening. Even though the demand isn't hot for it right now, there's going to be a surge for good transmissions when people can buy these trucks/cars/motors/transmissions for pennies on the dollar. Unfortunately, I feel like we'll have to wait that long in order to see results, but oh well. Just to give you guys an example: In the next year or two (2019 or 2020), I'd like to go turbo with my truck. (Doing all the supporting mods before going there minus built bottom end until I see where I can get with stock bottom end before sending a rod through the block or oil pan) Ideally, it'd be best to have a transbrake in that application with 2-step, but can't do it on the new transmissions. So, 4L80 seems to be the option, but I can't do that either because no one supports adapters or harnesses to make them work with the new motors/ECUs. That's the boat I'm in. I like to research everything before I go whole hog into something. Risk assessment, I guess.
  19. I got a used truck back in September with a lucky 17500 miles on it when I got it. So low miles compared to the 28000 miles on the Subaru Crosstrek I traded for the truck even though they were the same year. I got the truck to tow my new travel trailer that I am full time living in as I create a business to travel the country to see what is out there. Tired of the office life. I got the gas version and know a diesel is better but the smell of the exhaust gives me migraines and I don't know how to fix them. So I purposely went for the gas truck. The travel trailer I have is only 8000lbs GVWR so I am well under the max towing of the truck. I look forward to doing some research here and looking into upgrades or changes that might fit my needs.

  22. Like New 20" GMC Sierra OEM 6 Spoke Rims. These have the original tires Goodyear Wrangler 275 / 55R20 installed as well with ~4-5mm of tread left.The rims are in perfect shape, no scratches or gouges, they have been babied and only have 36K miles on them.See the photos below, they were just washed (sorry for the water on them) I swapped rims / tires for my truck and don't want these to go to waste. $1000 for all 4 Rims and Tires - Local Pickup or meeting
  23. hey yall, new to the forum but just got a 2016 gmc 2500 denali, have color matched the flares,and now adding cognito stage3 leveling kit with fox shocks. Looking for insight on what size tires i can run on stock 20s, with this kit without any rubbing. I want to go as large as possible. Anyone who has done this please let me know, pictures would be great. thanks in advance,
  24. The Sundae Drive does an in-depth video showing how to install an oil catch can for a 2014 Silverado 5.3L. What are the benefits of an oil catch can? Well if you visit the follwing sites you can read all about the benefits and importance of running an oil catch can. Catch cans are NOT ONLY for turbo/supercharger applications. They can be very beneficial for people with naturally aspirated setups. https://www.redline-motorworks.com/bl... http://oilcatchcan.com/oil-catch-can-... Purpose of your Stock PCV System: The PCV (Positive Crankcase Ventilation) system is designed to regulate and remove fumes from the engine crankcase and to alleviate crankcase pressure which could cause oil leaks or seal damage. The PCV system routes crankcase fumes into the intake manifold where they can be burned to eliminate harmful emissions into the atmosphere. The PCV valve controls the amount of crankcase flow volume depending on the engine's load. With large throttle openings (high engine loads), the more blow-by gases are produced, and the more the PCV system flows oil vapor into the intake manifold. A small amount of that ignited mixture leaks past the piston rings and ends up in the crankcase. This leakage is often referred to a "blow-by" or leakage past the pistons. Some of the oil mist and other products settle along the engine intake and over time form a "gunk". Our oil catch can collect the oil mist and condensed the fuel vapors while allowing "cleaner" gasses to pass back into the intake manifold. To pick up a Catch Can of your own go check out: http://www.eliteengineeringusa.com/ Here is the link for the E2 Catch itself and a diagram showing how it works! http://www.eliteengineeringusa.com/e2...
  25. I have a 2015 GMC 3500 that won't start without spraying ether. It will turn over, but unless we spray ether it won't start completely. Took it to Chevy, and they said they fixed it by fixing the fuel switch, and it continues. Plugged it in and no codes show up. Truck has 160,000 on it... HELP! ASAP. TIA.
