Hello Susan, thanks for reaching out. Yes, you can use a 50" Yakima Aero bar on your 2021 Toyota 4Runner. The 50" bar is actually exactly what Yakima recommends for your vehicle. To attach them to the factory rails, you will need the following:
- TimberLine Towers for Yakima Crossbars - Raised, Factory Side Rails - Qty 4 # Y33TR
That will be all you need. What were you going to use the roof rack for?
