The OpenSourceEV Parts Hitch Cover Thumbscrew V2 (Pair) fits the Rivian R2 and all R1S and R1T. The Rivian hitch cover is great when you are not towing, but the factory screws require a screwdriver to remove every time. These thumbscrews, with no modifications, let you remove the cover panel by hand, with no tools. They are effectively large thumbscrews that install as a direct replacement for the stock screws.
Important: Reuse the stock plastic washer from the stock plastic screw. Install each thumbscrew as a direct replacement for the stock screw, with the washer in the same spot. The cover will not retain properly without the washer.
This product is purchased from a third party, so we are unable to publish an open-source design for it. It is injection molded rather than 3D printed, because the torsional load of this application calls for it.
Customers praised these thumbscrews as a superior upgrade to OEM screws, making hitch cover removal "easy peasy" without tools. Reviewers noted "perfect fit" and robust construction compared to 3D-printed alternatives. While highly rated, some suggested thumb tabs could be 20% bigger and oriented along vehicle travel path to avoid debris damage.
Much easier than using the screwdriver, but the thumb tabs could benefit from being 20% bigger.
Much better than the OEM screws.
They fit exactly like the removed stock part, in fact, these SHOULD BE the OEM part fitted on R1T/R1S from now on. Great job.
Super easy to swap in; easy to remove or install hitch cover by feel.
Perfect fit on my '25 R1S. Installed last week, just used yesterday. Easy Peasy!
Easy to swap in for the OEM screws and much easier to use.
Pretty much a perfect item. I had tried a few 3D printed options, but after one snapped I decided to try these. Lower profile, but still totally useable… more robust. Fit my needs to perfection, so stop reading this review and just get ‘em!
these are very good, one suggestion would be to have the ends to point along the path of vehicle travel. Concerned with current way they sit more prong to rock or other debris damaging. Yes I'm being nick picky. Would buy again.
Would like to purchase a set. When will they be available again?
These are great! Easy to install, makes popping the hitch cover off a breeze!
Works as intended and easy to use. Great product!
Makes you wonder why Rivian didn’t make it easier in the first place. Work exactly as they are intended. Nice job.
Four stars because you haven’t actually open sourced this design. It looks good though.
Thanks for the review. Just an FYI, this is a third-party product that we don't own the rights to and unfortunately cannot opensource. I've updated the page to make that clearer. :(
I put these on my R1T and R1S. They work very well. Eliminates the need for a screwdriver to remove the cover plate.
Great way to replace the original hitch cover fasteners with ones that can be removed without a tool or coin or whatever was lying around.
