It is easy and lightweight to install.
Great quality rack with a huge amount of accessories that can be fit on it. For the 4Runner you’ll need to rivet nut the front portion and use silicone sealant around the threads. I’ve had this roof rack for years on my 2018 4Runner and it’s rock solid minus a few powder coating spots that are flaking off. Well built and plenty of accessories will keep you going on your adventures
Overall I am happy with the product, but I would suggest that when you use the rivnuts to upgrade to a better one. They seemed to short to truly do its job and seat flush. I ended up use some oem ones
