What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

I think the backup camera's resolution at nighttime is slightly better than that of a potato, so I swapped out the license plate bulbs with Sylvania LEDs in hopes of brightening it up back there. Haven't had a chance to see if there's any noticeable diff yet

I swapped my reverse lights and plate lights for sylvania led's as well. If anything, it made the camera quality worse because of the led in halogen reflectors reflected the light into the camera causing weird lines. I installed a pair of led lights under the bumper that work awesome. The camera is super clear now at night.

Oh man, hahaha. That's kind of funny/ironic - I guess I know what I have to look forward to now!

I bought these Husky/Weathertech knock-offs since they were on sale for $92. Their fit/finish are definitely on par with H/WT. The only two real discernible differences I can see: 1) for the two front liners, their coverage does not extend as far back/up into the foot wells, and 2) they're more pliable and not as rigid. Also, for the driver's liner, they do have two holes for those floorboard anchors. For $40 less, no complaints and would purchase again.

$650 full price or $570 on sale thats pretty steep for catch can or cans. I just watched video. He keept saying WOT. Cmon. Way too many hoses, tees and check valves to go bad
There is baffle on both valve covers so oil will have hard time reaching intake pipe in stock form
But if you liked, more power to you

Yes I have been known for overkill. I entertain the family!

Tell me about overkill. Some guys running just one wideband. How about dual pre cat and dual post cat widebands, plus dual EGTs and OEM 2 pre cat and 2 post cat O2 sensors

I have really bright LEDs in my tag lights and my reverse lights and now it's a slightly better potato

same here, i have a cree led style in the reverse lights...it is better, but the resolution leaves alot to be desired for such a pricey vehicle.

Agreed. I too have upgraded my reverse lights. My wife’s $25,000 VW has a crystal clear camera. Puts my ~$60,000 Tahoe camera to shame during the day and night.

Well, I had a chance to check out the change in quality/lighting/resolution. It might be marginally better at best, but at least it doesn't appear to be any worse off. I'll chalk that up as a win, hahaha.

Did a nice 3100 mile road trip up to the Pacific North West last week. Took the chance to take a nice photo to share.
My new K02's were nicely broken in on some dirt and gravel roads.

I brought the '18 in for first complimentary oil change as part of CPO program and the AC started blowing warm...they had it for 6 days and I walked out with new:

Rear AC evap hose (84524266 found a hole after pressure test/dye)
Oil cooler lines (84791853 tech said they were wet)
Radiator (84164905 tech said small leak)

Total bill was $0. 64K miles, covered under the 12 month/12K mile CPO bumper to bumper warranty, no deductible.

Since I plan on keeping this truck for a while like my '08, I'm glad to get all the new parts for free I possibly can lol.

Updated my Xineering Shock Sims to their new OBD unit this morning. My Shock sims for some reason kept throwing error messages, even after I cleared it with the software x100. We tried everything over months and nothing worked, so finally they sent me the new toy - their OBD solution, and man it worked like a charm. Also, shout out to Max and Bill over there for seeing this thing thru to completion for me. Class act, and a refined product.

New mods this weekend. Installed Norcalss 2/4 drop kit, Spohn Panhard bar and Eibach front and rear swaybars. Also installed new AcDelco hub bearings and did mod on splash shields for Wilwoods

Big fluid change day!
Did a full transmission fluid change and filter swap. Siphoned out through the dip stick until I got air then dropped the pan. Cleaned out the pan and the little magnet and changed gasket and filter.
Then changed the transfer case ATF.
Then changed both front and rear diff fluid and cleaned both magnets really well. (Rear diff has a ring magnet attached to the housing on the inside of the bottom for those who don’t know.)
Then changed the motor oil and filter.
Ready for some long road trips and a busy snow season at the end of the year.

I just did all this to the Yukon. Dealer did trans because 10 speed. Still a little sore from that one...

I haven't done the rear differential though. What fluid did you use? I put royal purple 75/90 in the front. Owners manual says 75/85 for the rear but options are super limited and pricey

I used Royal Purple in front and rear. Both 75/90.
It’s not enough difference to make a difference in my opinion.

My thought as well. I wanted another opinion before I did it though. Is the rear gasket reuseable? How many quarts and do you fill it until it ran out? I think Denali has a little different rear end but I've seen some stuff say the fluid level needs to be a little below the fill plug. I've never heard of that before. I've always filled them until it runs out?

Yes it's reusable, it's rubber and metal. I just used a razor blade to clean up the surfaces (obviously). And lots of brakecleaner to clean everything out before sealing it back up. And yeah, parked on a level surface, I just poured it in until it overflowed (same approach with front diff and then the ATF in the transfer case). And based on how many quarts I had, the amount I used lined right up to what the owners manual called for.

After more reading, I ordered the Mobil 1 delvac 75/90 for the rear. I'll get it changed out this week/weekend. Thanks for the reassurance!

75/90 for my front and rear diff. Not a single issue. Royal Purple!
