By combining a standard two-inch factory lift with high-end cabin amenities, it proved heavy-duty trail capability and luxury could coexist without compromise.\u003c\/p\u003e\u003cp\u003eUnder the hood, the optional L87 EcoTec3 6.2-liter V8 engine delivers 420 horsepower and 460 pound-feet of torque. This naturally aspirated, overhead-valve powerplant features Dynamic Fuel Management, which constantly deactivates cylinders to optimize efficiency without sacrificing peak output.\u003c\/p\u003e\u003cp\u003ePower travels through a ten-speed automatic transmission to an Autotrac two-speed transfer case. Off-road performance relies on Rancho monotube shocks, underbody skid plates, and an Eaton locker. This setup excels at low-speed technical crawling while maintaining composed high-speed highway manners.\u003c\/p\u003e\u003cp\u003eReplacing the older All Terrain package, the AT4 became a highly sought-after trim, representing over twenty percent of Sierra sales. It remains a coveted daily driver and tow vehicle. While the extreme AT4X now sits above it, the standard AT4 remains the cornerstone of GMC's modern off-road lineup.\u003c\/p\u003e","brand":"Fish Racing Apparel","offers":[{"title":"Black \/ S","offer_id":54076622668090,"sku":"62292396362232286317","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ M","offer_id":54076622700858,"sku":"32108840717735839709","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ L","offer_id":54076622733626,"sku":"76370864671193591362","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ XL","offer_id":54076622766394,"sku":"77519481242683993189","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 2XL","offer_id":54076622799162,"sku":"24065528078651368689","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ 3XL","offer_id":54076622831930,"sku":"21201425793978173127","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/9754\/6042\/files\/mockup-back-greyscale_91aad857-123d-48bc-be65-dd22cbd13c02.jpg?v=1789613188","url":"https:\/\/fishracingdistribution.com\/products\/2019-2026-gmc-sierra-at4-monochrome-cotton-t-shirt","provider":"Fish Racing Distribution","version":"1.0","type":"link"}
