JEBINC’s Review and Installation of the EV Sportline / 1EV / RMaxx Running Boards – Including Lessons Learned, Tips and Sealing of 4” hole procedure!

[madgrey]

Sealing the added holes with the gorilla seal is a better option, IMHO. Keep in mind, Rivian ships them sealed from the factory. And, it’s quite wet in Seattle, and the Gorilla seal is still 100% still like the day I installed it.

I pressure washed the bottom the other day and noticed the Gorilla tape basically looks like it was just installed. Only four months but it looks like it's going to last.

Due to the gravel roads where I live, I get quite a bit of dust accumulation under where the mounts are, especially near the front tire. On my previous truck, the dust would fill the hollow molded mud flaps and it was a constant battle keeping the extra few pounds of gravel out of them. For my R1T, I think leaving the hole open would allow the dust to accumulate which basically turns into concrete when wet.

Same experience and expectation! The Gorilla seal is a great DIY’er for the average person! Easy-peasy!

Checking back in on this… I am getting ready to install my rails now. How has the tape held up?

Has anyone tried to use rubber grommets as opposed to the seal/tape? I wasn't able to find mention in other threads, although I could have missed a mention.

I found these on Amazon with not a single review. Seems to fit a drill hole of 4" (100mm), which I believe would work.

That's covered in this thread, early on.
