Can Yakima Fatcat 6 Carrier be Adapted to Fit Top Channel of Crossbars
Updated 12/18/2025 | Published 12/17/2025 >
Question:
Do you have a part that fits the fat cat 6 and also works to secure it to the Rivian R1t’s crossbar but within the T channel it has?

Hey Brett, yes you can adapt your FatCat 6 to fit to the top channel of your Rivian crossbar by swapping to the hardware kit part # 8860085. What crossbars do you have on your Rivian?

I also have the clamp style currently so I don’t have the wingnut on the inside it’s just a bolt threaded down and it seems the part you tagged doesn’t come with wing nuts to secure that slot system to the fat cat?

Just the standard Rivian branded crossbar system, I think there’s only one iteration?
