2019 GMC Sierra AT4's Off-Road Performance Package Actually Adds Power

2019 gmc sierra at4s off road performance package actually adds power

If you need to get somewhere off the beaten path just that much more quickly than The Other Guy – or maybe you simply want to one-up your neighbor and their new Sierra AT4 – GMC has an answer for you.

Despite being only about three seconds old, The General is already throwing a new package at the 2019 Sierra. Meant to layer on top of the off-road focused AT4 trim, this new option adds even more horses to the hand-of-god 6.2-liter V8.

And, for once, buyers actually save money by selecting the option package. Speed normally costs money – but not this time.

GMC says the Sierra AT4 Off-Road Performance Package has an MSRP of $4,940. For such a sum, owners will find themselves in possession of 15 extra horsepower and 9 lb-ft of torque, bringing output of the 6.2L to 435 hp and 469 units of twist. Bundled in the package are the 6.2L engine, GM’s cat-back performance exhaust system, and a performance air intake. A set of 275/65/18 Goodyear Wrangler M/T DuraTracs are part of the deal as well.

Breaking things down, those rubber hoops are available as a stand-alone option for just $295, which is a pretty good price all on its own. The performance air intake will set a buyer back $695 if they order it a la carte, while the cat-back performance exhaust system costs $1,595 all by itself.

Basic math teaches us that these items, already available on the GMC menu, tot up to $2,585. This means those who check the new AT4 Off-Road Performance Package option box are shelling out $2,355 for the hi-po “six-two.” If selected as a solo item, the stock 6.2L V8 adds $2,495 to the truck’s bottom line.

Save $90 and get more horsepower? We think that’s a good deal.

Introduced along with the rest of its high-trim models earlier this year, the AT4 is intended to compete with the Ram Rebel and its own half-brother, the Silverado Trail Boss. It has a 2-inch lift and a few skid plates right from the factory, along with off-road-tuned Rancho monotube shocks and a locking rear diff.

Unlike the Ram Rebel, whose styling suggests it constantly THIRSTS FOR BLOOD, the AT4 is content with its black-chrome finishes and color-keyed body accents. Take note: a Chevy Truck rep told me earlier this year that the Trail Boss gear can be dealer-installed on any trim Silverado, so it stands to reason the same applies to the Sierra and its AT4 equipment. If you want a Denali with a factory lift, go for it.

The Sierra AT4 Off-Road Performance Package is available now.

    @Jon From GM's business standpoint, why sell base trim+'preferred' goodies when GM can just upsell you for a higher trim? You said it yourself, customers are willing to plunk down the extra cash/longer loan term anyways. So in reality It's less than the 20000 additional trucks you claim in your mafff (in which you applied 1 anecdotal sample to the entire Chevy/GMC dealer network). If it made sense dollar-wise, they would build them.

      As frustrating as it it, you are correct. GM probably performed a detailed cost analysis and discovered that the profit from selling fewer premium trucks is greater than the profit from selling more lower level trucks. I just dont like electronic gadgets since i drive my vehicles to 250,000+ miles. They tend to be expensive to repair when the break.

    "A set of 275/65/18 Goodyear Wrangler M/T DuraTracs are part of the deal as well." Real actual sidewalls! From the factory! It will just make me shake my head harder when I inevitably start seeing them with wagon wheels on them to make the Bros feel better.

  • Slavuta Civic EX - very competent car. I hate the fact of CVT and small turbo+DI. But it is a good car. Good rear seat. Fix the steering and keep goingBut WRX is just a different planet.
  • SPPPP This rings oh so very hollow. To me, it sounds like the powers that be at Ford don't know which end is up, and therefore had to invent a new corporate position to serve as "bad guy" for layoffs and eventual scapegoat if (when) the quality problems continue.
  • Art Vandelay Tasos eats $#!t and puffs peters
  • Kwik_Shift Imagine having trying to prove that the temporary loss of steering contributed to your plunging off a cliff or careening through a schoolyard?
