NHAT4

I don't recall the wire color. Use a multi meter / test prob while someone places truck in reverse...

If you are wiring in additional reverse lamps , pull the talilamp assembly and tie into the reverse feed there. Thats what I did. No issues..

Plenty of room on the passenger side to add a second or saddle tank... even if its not a full size but add another 15 + gal Just looked under my double cab and there is an easy 15" of usable space in front of the current tank just vacant... Yes it crosses the cab / bed plane but its all the same frame...

I have a new grill to install on my AT4... I'm dragging my feet cause it looks like a bitch... Per the instruction, remove wheel well trim, remove lower under grill trim, then as above....

Yup... the 24 sucks.... especially coming from my Duramax with a 59gal tank.. These frequent fill ups are killing me...

To me it's a regular bed.. It's the 6.5' . The tiny little bed that comes on The Crew Cabs is way too small for me especially with a toolbox mounted

Everything I read the AT4 front wheel opening is smaller than the TB... FYI

I posted this in another thread today....on the difference... Sounds like horse sh#t to me.... I'm at work right now an I have a 2019 AT4, and a coworkers 2019 TB. I just looked under them and same control arms and same strut part #s... Motofabs site list same part # for both too...

Agreed there maybe hidden soft codes, but they don't affect vehicle operation...

LEDS draw such low amps, and I yes the BCM is finicky , but i wired back up LEDS and additional bed lighting, into the respective lamps direct... No issues...

flowmaster 40 is not bad, but if you want loud... maybe the 10 series... Def on the spray liner....

2019 AT4, Readylift 2" front level and 3" blocks in rear to keep a small rake... Vision 18x8.5 0mm offset w same tires Duratracs 275 65 R18

Looks good, but take it all the way and lose the Z71 badge and go w a vinyl decal... will look even better... My 2 cents

If you are mechanically inclined and have a jack stand and floor jack you can do this yourself and save $$... or buy the parts and have a local shop do it...for less than dealer... its an 1 to 1.5 hrs of work then alignment... Most of the level kits being installed are " not for the AT4" but they work as is shown by the number of members doing installs.. I'd be curious the dealers response to the pro comp not being AT4 compatible... but as mentioned they work... In order to void a warranty it has to be proved that it caused a failure... I'm running the readylift 2" level kit and 3" blocks rear... Good luck

2019 AT4. Readylift 2" level kit front and replacement 3" blocks rear, Vision 18 x 8.5 0mm offset, Duratrac 275 65R18. Debadged and rebadged, Magnum rack, toolbox and Extang 2.0 trifold cover, ARE window vents.

Thanks..., they are Vision wheels, 18x8.5 0mm offset w the Duratracs that came on the truck. Yes sold the running boards

Pulled the running boards w in hrs of owning mine...

Rebadged after debadging her... Vinyl graphics...

Just read the instructions... Looks like RC is using a spacer in the strut spring and another under the lower mounts. so essentially 1" up top and 1" below.... I don't see the significance in this over 1.5 / 2" spacer below the strut... Plenty of installs with the standard level kits being used since the AT4 came out and yet to see any poor reports. If it turns out later there are issues w upper ball joint angles, then newer upper control arms can be added. ( I did this on my 2013 2500 a few years ago. ) So far it seems that the standard levels kits work,... But no feedback and I suspect we wont get any...

Headache rack install

Thanks. New graphics to replace the chrome badging

Drove away and halfway down the street the radio was on but not playing... I could scroll channels / stations inputs but no sounds.... Then when I got to my destination, the E parking brake set it self... Later that day, radio worked and after parking again, I went to the truck 5 minutes later and got something out of the back seat and closed the door and the parking brake set itself again... Called the dealer they said maybe it needed a software update. Before getting to the dealer I got a call on a recall/ update that needed to be done... Been working since.. My GMC needed a software update? Are we driving cell phones now?
