Considering 2500 AT4X

I get it now đź’ˇ; it's only something used on non-black vehicles or is it. Looks really bad. Hang on, let me take a closer look at mine. Hah! I'll be darned! Even my Black Onyx has the same covering but its not bubbling or anything.

Man, black trucks sure are beautiful when they are clean!

I’m not a fan of the black wrap on my tailgate. I don’t get it. I just haven’t screwed up the courage to get after it with a heat gun yet.
 

@pinebaron or anyone else with an X.

Is this a removable plug to be able to install rear lights? Just right of the park assist sensor...

Yes. AEV also makes brackets designed to mount lights in those spaces. I’m working hard to find somebody at AEV who actually knows about the AEV GM product line. When I get the information about all the part numbers, wiring harnesses (if any), confirmed lighting options, and fairlead options, I’ll post them. You’d think this would be an easy five minute phone call, but it’s been a real goat-rope. :ROFLMAO:

No idea but I'll take a look this morning; have an appt with the dealer this morning to loosen/tighten rear shackle bolts as a first step to eliminating rear spring squeak, I think the only recent issue I've experienced.
 

I totally miss my stereo in my '16 Ram Laramie Longhorn with the Alpine system! I replaced the 8" factory subwoofer with a JL Audio...what a difference, but even the factory system on the Ram was WAY better than my AT4X!
Yup.

My wife drives a Jeep Grand Cherokee. We are both perfectly happy with the OEM audio in that. I’d give it a “7” on a scale of 1 to 10. I still have my 2018 Ford Raptor too. The stereo in that is better than the Jeep — a solid “8”. (I need to sell the Raptor… It’s awesome, and I love driving it, but I can’t afford to keep two expensive trucks. Anybody want a low-mile Raptor? ;):cry: (My rating scale is based on my experience with OEM stuff. I’m not including the super high-end stereos people invest crazy money in.)

I drive a Tahoe as a work vehicle now, but until six months ago I was driving a stripper charger with cloth seats and rubber floors. (I’ve had three of those). The OEM stereo in the Chargers was a “6”. I’d say the stereo in my AT4X is a “4” or a “5”, so I decided to improve it.

Last week I dropped $2300 to improve the stereo. I added new Hertz seperates up front, Hertz Coaxial speakers in the rear doors, and twin JL audio subs under the back seat (which loses the storage, which I really wanted to keep).

The OEM Bose speakers are very efficient — so they require very little power to produce reasonable volume. That means many of the great aftermarket speaker options will not perform well without adding an amplifier. Some Hertz, Focal, and a few others don’t require amps to work okay. I liked the Focals, but preferred the Hertz.) The JL subs are amplified and have a dash-mounted knob so the bass can be controlled separately which, for me, is more hassle that it’s worth. I have not had to mess with the stereo settings in my Raptor in five years, and it sounds good whether I’m listening to 70s and 80s rock, country, or classical violin. I wish I could duplicate THAT in the GMC.

The new stereo sounds very good — maybe an “8” — IF the volume is turned up above conversation level. It’s even better if I’m patient enough to “tune” all the setting just right for a particular song, but if I do that and then switch music type it doesn’t sound quite right… too much bass or too little bass, etc. I don’t want to drop another $2000 trying to improve it more, so I’ll probably just learn to live with it. (Though I may replace the lousy OEM midrange speaker in mid-dash.)

It’s not like Dodge/Ford/Jeep/Honda are spending big money on their OEM stereos. I suspect GM could have made the AT4X stereo a “9” with an additional investment of less that $200 per truck. Just swapping the silly 5” sub for a powered 8” sub would have been transformational, and speakers are crazy-cheep when you’re buying them in lots of 20,000… I guess they just didn’t care. That seems strange, as a great stereo can help sell a truck the way a great garage can help sell a house.

Both my black vehicles always look beautiful and clean, the new truck and the older Merc, as if they came out of showroom; yes they do get dirty but are cleaned promptly. Not suggesting anyone agree with me but I'm obsessed with keeping most things shining clean, especially what I can; the list is endless and that includes our home window/door panes, chrome faucets, floors, door handles, quartx or other counters, range hoods etc. It helps prolong their life besides keeps them looking new, fresh and elegant; I blame my wife for it :)

Replacement rear leaf spring assemblies ordered by my local GMC dealer.
 

Yikes… I can’t recall ever hearing of spring packs on a vehicle failing.
Most folk may not have not have noticed or felt it is normal but there were squeaks and groans I could hear. Easy test, stand and jump on the tailgate step and check if you hear any rear leaf spring creaks. The dealer checked two brand new trucks on their lot and at least one had a similar although not as bad, a squeak. With hardly 3000 miles now on my truck, I like it to sound perfect in all respects with no squeaks and groans.
The Tech stated theres excessive friction and binding between the springs even after completing actions in bulletin #20-NA-022. Recommend replacing the leaf spring assemblies.

Yes. AEV also makes brackets designed to mount lights in those spaces. I’m working hard to find somebody at AEV who actually knows about the AEV GM product line.

Did you purchase/install these brackets/lights yet?
 

Anyone figure out what we can do with these two holes in the front bumper (mines an AEV edition); I htink some lights can be installed for sure and could perhaps link them to main beam or fogs. Ideas?

My bad... just realized you said it was your front bumper. Looks like the link i shared was specific to the rear bumper. Not sure if the same light kit would work in the front. The holes look the same.

For the rear bumper, I have already ordered AEV brackets from AEV and recommended Baja lights although I selected amber rather than clear lights. The front opening seems larger than the rear but I'll go measure it.
