GMC OnX6+ 30 Inch Grille Light Bar Kit - GMC 2018-19 Sierra 2500HD/3500HD

The Baja Designs GMC 2500/3500 HD OnX6+ 30 Inch Light Bar Kit is a vehicle-specific off-road lighting solution built for truck owners who need serious forward illumination without compromising the factory look of their rig. The OnX6+ bar runs in a Driving/Combo beam pattern, pushing light deep down the road while spreading enough width to cover the shoulders — exactly what you need when you're hauling a load down an unlit highway or threading through trail access roads after dark.

What separates this kit from a generic light bar purchase is the precision-fit mounting system. The brackets are engineered specifically for your HD truck, tucking the 30-inch bar cleanly behind the grille with no drilling and no modifications required. The result is a factory-clean install that looks intentional, not cobbled together.

Baja Designs built the OnX6+ around their CopperDrive technology, which ensures every LED is driven at full capacity, and MoistureBlock sealing that keeps the internals protected whether you're catching rain on the highway or crossing water on the trail. Battery Management Technology (BMT) adds an extra layer of protection by eliminating flickering and guarding your truck's electrical system against voltage spikes. This kit is for the HD truck owner who expects professional-grade performance from every component under the hood — and on the bumper.
