My 2019 AT4 Carbon Pro came with cat back, but not the air box. So I picked up an OEM cold air box and asked dealer to do tune also when they installed - they looked at me like they had no idea what I was talking about. I showed them some write ups from GM where it states tune is part of performance package. They said they would look into it. When I picked truck up they said the tune instructions were in the instructions for the air box install, so the tune was added - so I now have the performance package complete! So if you add OEM airbox, you will get that updated tune!

I ordered these on 2/5/20 - initial ETA was 2/13/20 - now - back ordered - no ETA - so I wait! Going in on 2/21/20 for alignment since level kit and front UCA's went on, a couple to recall's and for fix to my kicker speakers in tailgate - which only work part of the time, add black exhaust tips and to add GM performance air box. I have 2019 AT4 carbon pro - so it came with cat back exhaust, so I wanted to add airbox to maximize airflow with OEM parts. Be nice when it is all done!

Here is my AT4 stock wheels -

I did the Ready Lift SST kit which includes front upper control arms to correct geometry (for AT4 and Trail Boss), spacers and spring perch adjustment along with 1/2" taller blocks in rear (3.5" vs stock 3"). Stock shocks are retained or you can upgrate to King/Fox/ICON etc. Not sure what folks are doing for standard trucks, sorry if that is what you are asking. Most level kits for AT4 and Trailboss to not included upper control arms, see this video to understand why they are needed: Link:

Ready Lift SST leveling kit for AT4/Trail Boss - 1.5" in front and about 0.5" in back to level truck off. Includes new upper control arm for the front to retain factory geometry. Max tire zie for this kit - AT4 305 / 55 / 20 - Trail Boss - 295 / 65 / 20 - per Ready Lift - I still have stock 275 /65 / 18's that came on my truck . Before and after photos

Truck leveled - Ready Lift SST kit - before and after - before front was 38" +/- (ground to bottom of fender flare) and rear was 40" - now 40 1/4" front and 40.5" rear - Added Black Method NV wheels 18" x 9" as well

That is how I ended up with an AT4 - on Trail Boss, I could not get cooled seats, 6.2L engine, rear cupholders, amongst other things so I moved on to AT4 where I got all the things I wanted. I understand at a cost as it was a more expensive truck.

thanks that is awesome! I assume one part number is for driver side and one for passenger side - what about tailgate - is it driver side part number or passenger side? Thanks John

Looks great - plastidip on the GMC logo looks great- makes it blend. I also have dealer trying to sourcre the black AT4 emblems for my 2019 Carbon Pro - which came with standard chrome ones Any part number information or where you sourced them would be great to know. Thx for posting

Even if just leveling your TB upper arms are recommended. If you just want to level the Ready Lift SST kit is the best bang for the buck - $510 plus tax, free shipping from Tire Rack for the AT4/TB. If you want to add upgraded shocks down the road you could, but it would not be as "complete" a designed system as BDS is offering - so you just have to decide how many $ you want to spend the pick your best option.

I got this one from GM: link: https://www.shopchevyparts.com/cargo-management/2019-sierra-1500-front-center-console-organizer-with-coin-holder-black/84106530-p-92301815.html May be overkill - but give a few spots and fits into stock center console nicely

Taked to Transferflow again today - they currently don't have any plans to build a replacement tank for Chevy/GMC 2019 + - maybe a bunch of email showing demand would help them change their mind! They are selling all the tanks they make, as fast as they can and are not ready to allocate design time to another tank at this time. Have in bed tanks - but a no go for me.

is your truck and AT4 or Trail Boss- if so how does the ride compare? AT4 street ride is really good - want better shocks, but not at the expense of the ride quality

Here is another quality option, better shocks, covers the front - then you have to add a rear set up like BDS - price shown is with 2.5" adjustable kings Baja Link: https://www.bajakits.com/i-31570226-19-silverado-sierra-1500-4wd-upper-arm.html?ref=category:1459192 19+ SILVERADO/SIERRA 1500 4WD UPPER ARM (0) Reviews: Write first review SKU:C10U19 Shocks Sold Separately Shipping: Please contact us directly for International, Hawaii and Alaska shipping FREE SHIPPING!

I did not specifically ask about diesel - in reviewing their website - looks like gas for F150 and Toyota Tundra - all other replacement tanks they make are diesel for HD trucks (Ford, GM, Ram and Nissan). They also offer 50 gallon replacement tank for Ford F150 diesel for 2019. link: https://www.transferflow.com/shop/replacement-fuel-tanks?noncompat=true

I have been looking for a replacement tank that is larger than stock 26 gallons in my 2019 AT4. I have used Transfer Flow for replacement tanks in my last 4 trucks (3 diesel) - for my 2014 Raptor they made a 50 gallon replacement tank, which replaced the stock 36 gallon tank, which was awesome. 26 gallons sucks for road trips and given my commute is 120 miles round trip I am at the gas station three times per week! For towing even worse - GM should have at least put a 36 gallon tank in the truck. Right now neither Transfer Flow or Titan have a large replacement tank available. I have spoken with Transfer Flow and they are developing a larger tank, not sure on size yet and then have to get DOT approval of tank - a process out of their control, so they can't predict when something will be available for the new truck - hopefully by this summer. I will keep watching to see what comes out as a larger tank is an immediate upgrade when available.

Hi Drew I leased an AT4 on 6/30 - post on page 31 has the lease details. I live in S.Cal and not many dealers would offer much off an AT4 other than the factory rebates. I talked to at least 15 dealers who had trucks I was interested in. I had one dealer more aggressive than the truck I bought - but found out after they gave me the pricing the truck has 450 miles on it and they had it on the lot for 5 months - $70k MSRP. They offered similar discount to what I got, plus they threw in $2k in dealer cash - so about $10k disocunt. The Carbon Pro Edition I got was exactly what I wanted - It was in Phx (350 miles from me) - dealer is shipping it to me at no cost to me. All the paperwork was done in the mail. Great to work with. MSRP $66,635 Dealer discount $4,362 Rebates $3,650 ($3,400 on GM lease and $250 for GM Loyalty - 2015 Z/28 bought new from GM) Total Discount $8,012 Net cost $58,623 + tax and License So not as good as some deals posted here, but I got exactly what I wanted and got a good discount. Big volume dealers can offer the biggest discounts as they get GM cash for sale volume, they can apply to future sales. So bigger dealers with lots of inventory will provide the best deals. I think the incentive for the AT4 went down in July for a purchase from $3,500 to $2,500 (leases are $100 less). There are other rebates, for example I got the $250 loyalty rebate for the purchase of a new 2015 Z/28 a few years back. There is an educator rebate, a first responders rebate, a military rebate and of course best of all is the GM friends and family rate. Working with a dealer who knows everthing that is available is key to getting the most off on your truck. You will encounter some that say I will give you rebate and discount the truck $1k off - you likely will not make a deal with those dealers - Tell them what you want and stick to it and go to multiple dealers - you will find some will not be interested in your deal, but likely someone is for whatever reason - maybe they need one more sale to hit the next level of incentive with GM - end of the month is best time to get biggest disocunt. However now inventory of 19's will be all delivered by next week - so strike quick, as inventory drops it might be harder to find what you want at the price you want! I had a dealer call me this week who said no way to my offer two weeks ago saying we can do the deal - I said no longer interested, they offered a better deal - I then told them I already bought a truck, but thanks for the call. So dial for $$$$$$$ Good luck finding what you are looking for!

From a what did you pay perspective MSRP $66,635 Dealer discount $4,362 Rebates $3,650 Selling price $58,623 Discount of $8,012 - or 12% Plus tax and license wherever you live - the lease is just an easy way to buy an expensive depreciating asset, lock in your downside and give yourself the option to keep or give back at the end. Just got lucky on the Carbon Pro, was looking for a black one with what I wanted and came across it on their webste - did some research and realized it had everything I wanted, plus the carbon bed, which I wanted but was told I could not get until 2020 - so win - win. Guess there will only be 500 Carbon Pro AT4's for 2019 - and was also told for 2020 the price will go down for the package, by $2k or so. However the reason why is because the performance package (exhaust, airbox and factory tune) will not be part of the package in 2020. Was told by the dealer that the performace package will no longer be offereed in 2020 on any Silverado or Sierra - GM will only offer cat back exhaust, dealer installed - not from the Factory - they will no longer offer the air box or the tune in the package in 2020. That would be a bummer, as it is nice to get a factory engineered package with full warranty! Will post up photos once the truck arrives.

I leased a new AT4 Carbon Pro Edition 6/30/19 for 36 months, 12,000 miles per year MSRP $66,635 Dealer discount $4,362 Rebates $3,650 ($3,400 on GM lease and $250 for GM Loyalty - 2015 Z/28 bought new from GM) Residual $41,980.05 - 63% of MSRP (10k lease is 65% and 15k lease is 61%) Drive Off's $1,800 - taxes on capitalized reduction, fees and 1st payment, plus $655.96 capital reduction Base Payment: $696.05 Taxes $53.94 - specific to my zip code in San Juan Cap, CA Total PMT $749.99 - including tax Interest Rate: 5.06% - GMC buy rate - so not great - Trail boss has 3.7% - but overall I was very happy with the outcome. Very happy with the Lease and to get a Carbon Pro Edition! Truck is in transit to the Dealer, they will add painted molded fender flares (my cost $690 installed, same as GM option cost) and they are paying to transport it by truck from Phx. to Orange County (about $400). Dealer (Henry Brown GMC - Gilbert AZ) was super easy to deal with - sent email and told them what I wanted (drive off's only and $750 per month total pmt) - and which truck from their inventory by VIN - they called me back 10 minutes later and said - ok - overnighted me the paperwork, I overnighted back - done deal - 20 minutes start to finish! Just how I like it. Now hard part is having to was 10 days to 2 weeks to get the truck! Lease will start when the truck is shipped. Can't wait to get it.
