> I’m torn between the no-drill versions and the more heavy-duty rubber flaps. Since the Trailblazer has a bit of a unique trim shape, I want something that fits perfectly without looking bulky.

Quick question - are you driving the RS or the ACTIV trim? The body molding is actually a bit different between them, and what fits an LS might look super janky on the RS trim.

I've been messing with SUVs for years and honestly, I'm usually a big fan of WeatherTech MudFlaps because they have that laser-measured fit that looks like it came from the factory. I have them on my daily and I'm super satisfied with how they handle winter slush. They aren't bulky at all and literally take 10 minutes to install.

But if you're worried about those gravel rocks really doing damage, you might wanna look into Gatorback Rubber Mud Flaps. They're more heavy-duty than the plastic ones, but they can be a bit more work to mount. I've found the hard plastic ones like GM Genuine Parts Front and Rear Splash Guards offer the cleanest look, but rubber ones flex better if you ever hit a deep snow bank. Anyway... let me know which trim you got and I can give you a better technical breakdown of what'll actually fit your wheel wells right! Peace.

Respectfully, I'd consider another option besides the rigid molded flaps like WeatherTech. I've tried many different setups over the years, and honestly, those "perfect fit" plastic ones can be a nightmare for your paint long-term.

• WARNING: Rigid flaps trap grit! Basically, dirt gets stuck between the flap and the body molding. As you drive, it vibrates and literally sands your paint down to the bare metal. It's a huge rust risk for the Trailblazer's wheel wells.
• Safety-wise, rigid plastic doesn't flex in the cold. If you hit a chunk of ice or a curb, they can shatter or rip the mounting points right out of your trim, which is SO annoying to fix.
• In my experience, a flexible rubber flap is way safer for winter slush. It wont snap when it gets weighed down, plus it actually deflects rocks better without that annoying "pinging" sound.

Its definitely worth considering the reliability over the looks... just my two cents! lol

Quick question - how much are you actually looking to spend on these? I've been through a few different setups over the years on my SUVs, and honestly, the choice between the no-drill plastic ones and the heavy rubber ones usually comes down to your budget and how much work you wanna do. The pricier rubber ones handle winter slush way better in my experience, but they can get expensive fast. Let me know what your price range is and if you're comfortable drilling into the trim at all!

For your situation, I totally get the struggle cuz that gravel driveway will literally eat your paint if you're not careful. Honestly, I've tried a couple of different setups on mine and it's kinda tricky with the unique trim shapes on the newer Trailblazers. Before you buy anything tho, what trim level did you get? Is it the RS or the Activ?

Anyway, here is what I've found:
- WeatherTech: The no-drill ones look super OEM and clean, but unfortunately, they didn't hold up as well as I'd hoped in heavy winter slush.
- Husky Liners: These felt a bit more heavy-duty for the price. Not as "pretty" maybe, but they actually catch the rocks better imo.

I've noticed the no-drill versions sometimes leave a tiny gap where salt and grit get trapped, which is literally the worst for rust later on. If you're okay with a tiny bit of drilling, the protection is way better... gl!
