I finally found and installed an aluminum rack on my 18 ORP that used the original Toyota side rails, and it worked out great. It has a low profile and looks OEM.
I did not want an expensive full rack from one of the major manufacturers. I need something for light to medium duty for camping gear, sports gear, and transporting lumber and items from the hardware store. The OEM crossbars that came with my 4Runner are not very useful; they are curved and they flex. But the side rails are more than adequate for attaching aftermarket crossbars. This rack fits my needs perfectly.
This rack design was developed by

and is targeted at the 5th Gens 2014+. It is called the NiseRack. You may have seen his posts in another thread about DIY roof racks. This is the result of months of part research, design, prototyping, testing, and refining. He designed and manufactured the aluminum brackets and the attachment system for the crossbars. The crossbars are slotted AA 6063-T6 aluminum extrusions which you buy from TNutz or some other vendor. He enlisted me to test it out before releasing it to the public. It is now ready for prime time and available.
The brackets are reasonably priced and are available through his website at
Shop | NiseRack.com
The website also specifies the part number and dimensions for you to order the crossbars from TNutz.
