Couldn't load pickup availability
Give your 2021–2023 GMC Yukon Denali or AT4 a signature front-end glow with this bolt-on LED “Power” bar. The 6,500–7,000K strip tucks behind the factory grille, firing a vivid DRL accent that disappears when switched off. The anodized housing is fully sealed to IP67 for water- and dust-proof durability, with LEDs rated for 50,000 hours. Choose stealth-black or classic-silver brackets to match your build.
Installation is simple—bolt to stock points and connect with the included 2 foot lead to any 12V power source. For a no-splice option, add the optional plug-and-play jumper for a factory-style tie-in. The kit includes the grille light bar, stainless mounting hardware, 2 foot lead, and a six-month Sick Diesel Gear warranty.
