In this video I’m walking you through exactly how I’m fitting 37s on my third-gen Colorado using the AEV HighMark fender flares. This isn’t a “bolt-on and call it good” mod—there’s cutting, drilling, templates, and a little bit of that “send it” energy. I show you the real process: ripping the old flare off, pulling the wheel well liner with a T15, using AEV’s templates to mark everything, drilling alignment holes, and then getting after the cut lines so the 37s actually clear where they were rubbing. I also talk through the stuff people don’t mention—like how my truck’s already pretty clapped from running 37s, and how that makes lining up cut lines more annoying. I point out differences depending on your setup too: if you’re on an OEM ZR2 bumper you’ll likely be trimming more than I did since I’m running a DV8 tube-style bumper. And yes, I made a mistake you can learn from: don’t blast through your drill bit on the passenger side unless you want to drill straight into your windshield washer fluid tank (ask me how I know). Once the flares are on, the truck’s whole vibe changes—these look thick, smooth, and way more “proper” than the OEM ZR2 flares. I’ve already wheeled them, and for making 37s work, this is hands-down one of the best mods I’ve done.
