Matt, it's not only that wheel spacers are a simple part, but a VERY important part when it comes to safety. Bora makes the highest quality billet aluminum, hubcentric spacers on the market, they also come with the highest quality case hardened lug bolts. Hubcentric is essential because the load of the wheel is centered on the hub rather than the studs. This also means you will have no vibration from the wheel being just slightly off center, as it could be with non-hubcentric spacers. Read some Amazon reviews of the cheap Chinese-made wheel spacers and you'll understand. Stories of lugs breaking, wheels falling off, trucks being wrecked, front suspensions being ruined. Bora is the trusted brand, indeed the "Cadillac" of spacers. You can buy spacers for half the price of Bora, but is it worth the risk? Nope. As far as trimming lugs, it depends on your wheels. Factory wheels have a 1/2 - 3/4" indent on the back side which provides a place for the lugs to reside, but the spacers have to be at least 1-1/2" thick. Aftermarket wheels without the indents require 1-3/4" spacers.

I haven't posted in a long time... Today I put on some Ridge Grapplers 305/45/22 on GM Replica Wheels (ebay), no spacers, 2-1/2" ReadyLift, No rubbing.

I haven't been on the Forum for quite a while. Pretty busy with Life! ;-) I haven't seen a mug that ugly since the Rolling Stones last US Tour. What the hell could GM Designers have been thinking????

I bought an '18 Yukon SLT. Absolutely love the vehicle. City driving, we are getting around 16-17 mpg. Highway, 70 mph, 21 mpg. Headlights are terrible. BUT..... I recently replaced them with 6000k LED low and high beams. GREAT improvement! The low beams are slightly brighter than OEM halogens, and much better color, but the hi-beams are light aircraft landing lights! Traded in a '15 Acadia. Best move ever. PS... LED's are not recommended for low-beam reflector housings. Hi-beam reflectors are fine, because they won't be on with on-coming traffic. They work great in low-beam projectors.

I think the Tahoe/Suburban has the same DRL setup as the Yukon (separate lights), so the LED's in my Yukon should work. AUXITO LED headlight bulbs H11 / 9005

The '18 Yukon has separate DRL's, so I don't know. The 14 Silverado, I used a different LED bulb and the DRL's work perfectly, but they cost twice as much and the fan housings are twice as large: OPT7 Fluxbeam H11 LED Headlight Kit w/ Clear Arc-Beam Bulbs - 60w That's why I switched brands for the Yukon... needed the smaller fan housings and didn't need to be concerned about DRLs since they are a separate set of lights.

I have a 2014 Silverado LTZ and a 2018 Yukon SLT. I have changed all halogens to LED. They look good and no more yellow headlights. To be honest, the low beams are about the same brightness as OEM halogens (through projectors), but the high-beams are off-the-charts for brightness! (Because of reflectors). These are the LED's that I put in my '18 Yukon. AUXITO Automobile H8 H9 H11 LED Headlight Bulbs No flicker, no need for reverse-polarity adapters, plug-n-play. Bases are small, so they easily fit behind the dust covers. Even though the manufacturer said the dust covers didn't need to be ventilated, I purchased the flex-rubber dust-covers that allow fan to vent heat to the engine bay.

Yes Tasker is Android only. Pretty slick app. You can do a lot with it. I'll bet there's something like this for iPhone but I'm just not familiar with it.

Here's another thread on SLT vs. Denali headlights.... http://www.gm-trucks.com/forums/topic/192579-headlight-difference-slt-vs-denali/?tab=comments#comment-1986959

I don't have pics, but I can tell you there is no comparison. The HID's in the Denali are clean, bright, and 5500k which is pure white. I just bought a 2018 SLT Premium. It has Aweful halogen headlight bulbs. Same ones that were in my 2014 Silverado LTZ. I changed the Silverado bulbs to Fluxbeam H11 LED 6000k LED's. HUGE difference. I did the High and Low beams. They are brighter and the color is crisp and white. (also did the fogs 6000k.) So I'm considering doing the same thing to my new Yukon. HOWEVER..... Since I bought the FluxBeam's a couple years ago, the tech has improved and there seem to be several others out there. So I'm still researching. Yes, HID's would be a great alternative... I just like LED's.

After messing with this for a week, my IT-expert son installed the "Tasker" app on my phone instructing it to Load Pandora every time my phone connects to Yukon Bluetooth. Works perfectly every time. (May seem trivial, but I just don't like messing with phone while driving).

Robert Brogden GMC, Olathe KS... $16,712 off sticker. I just bought one from there. http://www.robertbrogden.com

For me, just too many downsides to the Yukon Denali. Mostly the $10k price bump. I just bought this 2018 Yukon SLT Premium, at Robert Brogden GMC, in Olathe KS, for $11k below sticker! The main reason for buying this SUV as opposed to the Denali (other than price) is the 5.3L, bullet-proof, V8, which has been a long-standing staple of the Silverado/Sierra for many years and is clearly one of the most dependable engines every built. Reason 2: 6 speed automatic. Enough said. Reason 3: I don't really like the Denali grille, power steps, and 6.2L engine for this vehicle. And............. I saved 10 thousand bucks by buying the SLT. Last but not least. I Love this vehicle. Extremely comfortable, quiet, luxurious, hi-tech, with all the bells and whistles and gets excellent mileage. We traded in a 2015 Acadia Denali that had an overall fuel economy of 18mpg. With just a few hundred miles on the Yukon, it's getting 19.2 with the same driving conditions. Wife loves it too.
