Correct, they are sold in pairs!

Any plan for rear door sills? Would be great step for my son. I know it’s a small area

Funny enough, we were just talking about this in the shop. We can't promise anything right away, but it's something we will be exploring for sure! It seems like a few people would like sets of 4.

Billet, but black, so they look like plastic? I was warming up to the idea of polished aluminum.

I would prefer it to match the color of Rivian plastic or better - aluminum color.

Just got these in the photo booth today, and we have to admit - you guys were on to something. Etched aluminum sills now available!

Just wanted to drop a little update:

Moving forward, we've changed the machining and finishing process to be less glossy, as we think the look is so much better!

Hey MPP! If I want the MPP logo etched, how do I specify that?

This is what I'd like, too. Will the fronts fit the rear on the R1S?

This may be my first "mod" once I get my R1S next week.

If you select "Yes" for Custom Engraved, you can just let us know that you want the MPP logo in the text boxes, and we can make that happen for you. Each one is manually processed, so we can always get in touch. We love that you want an MPP engraved one ?

If you can take a measurement of the flat section of the rear door sills, we can get you a solid answer on whether or not they will fit. If the door sills front and rear are the same, it will work perfectly! I know they unfortunately don't fit in the rear of the R1T because that passenger area is a bit narrower.

Perfect! I'll measure next week, and then be in touch

I am interested in this as well as I'd like front and rear sills for the R1S.

Hey Alex,

Any luck with the door sill measurements of the R1S?

There appears to be a good 16-1/2" flat section between the curves:

Thank you so much! This does mean that the door sills should fit the front and rear of the R1S. I'm going to shoot you a DM!

They fit great!

Yes, that's amazing! Thanks @SD_Engnr !!
