Best Rack Size for 4Runners

Best Rack Size for 4Runners

Does size really matter? When it comes to choosing a 4runner roof rack, most overlanding enthusiasts and off-roaders would probably instantly say YES—and they have all the reasons to say so. For those who do not know, not all roof racks are created equal. They come in various sizes, styles, and designs. 

Generally, the size or length you choose will depend on what you intend to use your rack for. 4th and  5th Gen Toyota 4Runner roof racks are typically used for aesthetic and storage purposes. 4Runner racks come in two main lengths: full-length and ¾ length. There is also an option to use crossbars instead of a roof rack for this type of vehicle. We will tackle these solutions in detail as we go along. 

For now, take a quick look at the snapshot below of how a crossbar, a full-length roof rack, and a ¾ length roof rack differ from each other.

Full-Length Racks

Full roof racks are the most popular among all three. They are the biggest roof platforms or systems available in the market that offer unmatched durability. They cover most of your 4Runner’s roofline—spanning from the front windshield all the way to the rear cargo hatch. Their massive size (consisting of up to 9 crossbars) provides the most surface area for your loads and accessories. 

Full-length racks offer the most 4Runner roof rack capacity, which is ideal for supporting roof top tents and awnings, carrying cargo boxes, or transporting bulky items like kayaks, boards, fishing gears, etc. Industry leaders like Prinsu, Front Runner, and Eezi Awn present many different roof rack lengths and widths including full-length ones. 



Crossbars (also known as roof bars) are the lightest and the easiest roof system to install on your car. They can easily be mounted to your existing 4Runner side rails and do not require permanent modifications to your vehicle. Crossbars are simple storage solutions with the least impact on fuel economy. They are perfect for those who only need a storage solution for lighter weight loads or those who are not into too much heavy off-roading. 

Nevertheless, just because you’re using a crossbar doesn’t mean you can’t have the best. Prominent brands like LFD dominate the roof bar space—offering awesome high-quality crossbars like their best-selling LFD Off Road Ruggedized Crossbar Bundle for 5th Gen 4Runners


¾ Length Racks

¾ roof racks offer the best of both worlds. They are cheaper than full-length roof racks but stronger and more functional than crossbars. They are large enough to carry bulky objects like tires, fuel containers, and other camping equipment. However, they may not have the desired room to support roof dwellings.  ¾ racks also offer unobstructed views through your sunroof.  

On the other hand, ¾ roof racks can get the job done if your main goal is to improve the look of your Toyota 4Runner. Some models and brands of these roof rack sizes even come with wind deflectors and light bar mounts. Prinsu roof racks, for example, offer ¾ racks with both features added as an option. Another well-known name for providing roof racks of this size is Front Runner. 



One size doesn’t fit all in selecting a Toyota 4Runner roof rack. Before making the big decision, 1) make sure you know what you need, 2) do your research on the most trusted brands in the market, 3) read customer reviews and feedback, and 4) consult experts in the overlanding space to get you the most value for your money.
