Are there any good mud flaps for the Rivian R1T?

In my experience, you really gotta look at the technical trade-offs between the "no-drill" options out there. I've tried many setups over the years, and for a truck as heavy as the R1T, you want something that won't flex too much at highway speeds but still gives enough coverage for off-roading.

I would suggest checking out these two based on your criteria:
- EV Sportline TMaxx Rally Armor Mud Flaps for Rivian R1T: These are basically the gold standard for durability. They use a flexible polymer that doesn't crack, and they're specifically designed to fit the existing wheel well liner holes.
- Abstract Ocean Mud Flaps for Rivian R1T: These are way more low-key and honestly look OEM. They're cheaper, around $80-100, and literally snap right into place without any drilling.

Basically, if you're hitting heavy trails, go with the Rally Armor ones cuz they're tougher. If you just want to stop the rock chips on the highway, the AO ones are a solid, cost-effective choice. Good luck!

In my experience, you’ve definitely gotta get some protection on those rocker panels cuz the R1T literally throws everything up there. Over the years of owning different trucks, I’ve tried many different setups, and for the Rivian, I’d suggest just going with Twraps.

I’m still kinda new to the whole EV off-roading scene, but here is what I’ve learned so far:

- Honestly, just get any of the bolt-on kits from Twraps and you’re basically good to go.
- They’re super easy to install without any drilling, which was a huge deal for me since I didnt wanna mess up the frame.
- They aren't like, massive or bulky at all, so they don't ruin the look of the truck but still do the job.

I mean, I was worried about the same rock chips tbh, but these have kept my paint looking fresh even after some muddy trails. Lowkey the best investment I've made so far!! gl!

Seconded!

late to the party but honestly, safety should be your top priority here because the R1T is basically a rock-throwing machine. in my experience over the years, you really gotta be careful with some of the cheaper no-drill options cuz they can vibrate loose or actually trap salt and grit against your paint, which is exactly what you're trying to avoid!!

I would suggest checking out:

* **EV Sportline** - I mean, they're basically the gold standard for Rivian accessories. super solid build quality and they wont fly off on the highway.
* **WeatherTech** - you literally cant go wrong with their laser-measured fitment. it's highkey the most reliable way to ensure you aren't drilling into the frame while keeping everything tight.

just make sure you're checking the hardware every few thousand miles, especially if you're hitting the trails. i've seen folks lose flaps cuz they didn't realize how much the truck flexes. gl!
