  1. I would definitely do it again. I think upgrading the factory HID bulbs on the Denali's is the best "bang for your buck" headlight upgrade you can do. It's a relatively easy and non-invasive upgrade, simply remove and reinstall low beam bulbs. There a plenty of nice options from OSRAM and Phillips for HID D3S bulbs that offer more lumens, better color, and more light output. Upgrading the headlights further from here would involve a headlight retrofit and that is significantly more costly and time consuming.
  2. Sorry for the double post. I thought my previous post was just an edit. (Is there no "Preview Post" option before submitting a post?). Personally I own a ‘15 Yukon XL Denali and decided to just upgrade the factory HID D3S bulbs to OSRAM CBI's. OEM stock HID on the right (passenger side) and OSRAM CBI D3S bulb on the left (drivers side). The OSRAM CBI offers a color closer to 5000K more white without decreasing light output. In fact I think they are brighter. This is plug and play as all you have to do is swap the OEM D3S low beam bulbs out for these. Again these are HID’s and since your Denali already has factory HID system all you need is a whiter bulb. I feel they are brighter and the color matches the LED DRL strip and my LED fogs nicely. It’s hard to capture headlight photos and color comparisons from in front of the headlight. They never represent the true color in real life. I would be cautious about purchasing OSRAM bulbs from Amazon or eBay. There have been some counterfeits sold through Amazon, which is represented in the significant price difference of Amazon compared to other legit retrofit headlight sites. I picked mine up from HID Concept because they had the best coupon code at the time, but also check The Retrofit Source or Lightwerkz. you should be able to find better deals around the Holidays; Independence Day, Memorial Day, Black Friday, etc. and get about 15-20% off.
  3. That's because in a lot of ways converting from HID to LED is a downgrade. Is it doable? Sure I suppose. How far back in the headlight wiring system do you plan to replace? The factory lighting has an OSRAM D3S HID ballast in-line. There aren’t many LED bulb options in the D1S, D2S, or D3S size variant. This is because converting from HID to LED is not a conversion many people are interested in doing. Quick search shows there are some LED to HID “kits” available; some apparently just plug into an HID ballast while others somehow bypass the HID ballast? Or don’t use it? The thought of popping in an LED Bulb into a HID projector powered by an HID ballast or some sort of HID ballast LED Driver bypass “kit” just does not seem like a great solution nor a reliable one. To be honest swapping from HID to LED in our GM trucks isn’t going to really solve your problem with light output either. The problem isn’t really the type of bulb, sure some can offer slight improvements, but the major issue is the GM bulb projector itself. The pics below are not my vehicle, they were pulled from the GMfullsize.com forum. Although, this vehicle is a 2015 GMC Sierra, knowing GM, I’m confident that the type of projector is very similar to the ones in our Yukon’s. Sure there are probably some slight differences between the Yukon SLT Halogen projectors and the Denali HID projectors, but knowing GM I also wouldn’t be surprised if the only difference was the bulb socket. I only say this because of the clarity and still obvious projector cut-off Yukon SLT (and Tahoe owners with halogen projectors) are achieving by just swapping from factory halogen bulbs to LED or HID into their factory halogen projectors. The light pattern and cut-off typically remains the same just brighter. Definitely an improvement over stock, but only addresses part of the issue. Let me show you what I mean... For all intensive purposes the pics from this 2015 GMC Sierra will show what I’m referring to. Here is a photo comparison when the factory halogen bulbs in this 2015 GMC Sierra were upgraded to HID bulbs: Sure the light is brighter, but look at the light output and beam pattern closely. See how there is a dark spot right in the middle of the light output and beam pattern and other random dark spots. Those same dark spots are there with the halogen bulb and the HID bulb. Swapping from an HID to an LED will be no different in your ‘18 Denali. Because the headlight projector and lens omitting the light output has remained the same. Now this photo shows going from an HID bulb in the factory projector to the same style (35W 5000K) HID bulb into a Lexus RX350 projector retrofit: Dramatically different isn’t it? No more dark spots, the light output is consistent and the same brightness is throughout the entire beam pattern. They’re both Morimoto 35W 5000K HID bulbs, the difference is the projector not the bulb. Sure there is an upgrade in light output going from halogen to HID or LED. I don’t think swapping bulbs from HID to LED, and vice versa for that matter, in our GM factory projector headlights is going to make that much of a difference. You want to fix the light output change the projector and do a retrofit. Sure it’s a lot more involved and more expensive. But it’s clear from these images the weak point of our headlights is the GM factory projector in our headlights, regardless of what bulb you use.
  4. I didn't take any before pics but here are a few pics of mine: 2015 GMC Yukon XL Denali lowered on Norcal Goodies: Belltech front drop spindles, Norcal Rear 1-4.5 Adjustable kit with Endlink/Bumpstop option and Rear Free Travel Mod Truck is sitting right at 34-1/4" Front Ground to Fender Lip and 34-7/8" Rear Ground To Fender Lip on 285/45/22's. Just a little over 1/2" rake. Very pleased with how everything turned out.
  5. I have a '15 Yukon XL Denali and I've lowered mine just slightly 1.5" Front/2.75" Rear with this kit here: https://tbssowners.com/store/index.php?act=viewProd&productId=609 Retains magnetic ride control and rides exactly like stock, with a bit less lean in turns due to lower center of gravity. Kit is super complete with instructions and everything you need.
  6. I purchased the wheels brand new from a Giovanna Wheel shop and have since chosen to go with a different set of wheels. Unfortunately the wheel shop I purchased from does not accept returns, so I am listing the wheels for sale. Wheels are brand new and unmounted, I only unboxed (1) wheel for picture purposes only, then it was repackaged with all the original manufacturer's packaging. Wheel Details: Giovanna Dramuno 6 Machine Black Finish Size: 24" x 10" Offset: +30 mm Bolt Pattern: 6 x 139.7 Center Bore: 78.1 mm Fitment: 2007+ Yukon/Yukon XL, Escalade, Tahoe, Suburban, Sierra 1500, Silverado, Avalanche, Wheels will ship double boxed and with all original manufacturer's packaging just as received from Giovanna. Asking Price is $1,750 OBO shipped to the continental U.S. Prefer Payment via PayPal I'm located in Dayton, OH and would be willing to meet up within a reasonable distance. Plastic Protective Cover still on Center Caps: One of the deepest concave style wheels available; About 3" Deep Concave from rim lip down to center cap: Repackaged with Original Manufacturer's Plastic Lip Protector: Some "Stock" Images:
  7. Nice looking truck. What kind of lights did you put behind the grill? LED light bar? I really like how from the first pic you can't even see that there are lights somewhere behind there when they're off. Nice work!
  8. Dr. Colorchip offers some really nice DIY paint chip repair kits. I’ve used them numerous times with great results. https://www.drcolorchip.com/
  9. Yeah I would definitely steer away from the grills with the mesh. The mesh would make it very difficult to clean behind. I like the one one in the last pic if it was available without mesh. It seems to fit and complement the lines of the front end the best, but that’s all just opinion...
  10. Yes it is very much a personal preference, and as shown above can really change the look of a truck.
  11. Just depends on what you're going for. Personally I think there's more to do with the type of tire in regards to ride quality, there are plenty of 20" and 22" tires for that matter that ride really well on the larger full size SUV's, and IMO 20's even look small on the newer large size SUV's especially with the LWB of the Suburban. As previously mentioned going down to 18's will make the wheels look VERY small, and somewhat out of place I think.
  12. Truck looks good. Kind of on the fence with the black stripes along the side, sometimes it looks ok, sometimes it looks like too much. Clean truck.
