Mounting Points Needed for Third Row Installation
When installing the third-row seats in your 5th Gen 4Runner, it’s really important to pay attention to the rear mount points that are specifically designed for those seats. Making sure these points line up properly is key to keeping the vehicle’s structure solid and safe.
Just a heads-up—some kits might need a few small tweaks, especially if you’re using aftermarket parts instead of OEM components. So, it’s always a good idea to double-check the fit and make any necessary adjustments as you go.
Required Rear Mount Locations
Although the 5th Gen 4Runner isn’t always set up for a third row, it does have designated rear mounting points that are crucial for a secure install. These points are usually located on the floor and side walls of the cargo area.
To install an aftermarket third row seat, make sure your kit includes brackets that match these locations. Sometimes, you might need to drill or make minor modifications if your vehicle didn’t come with a factory third row.
Always check your service manual or talk to a professional installer to confirm the exact spots and compatibility before you start.
Structural Compatibility Considerations
Since the 5th Gen 4Runner has factory mounting points for third row seats, making sure these line up correctly with your seat kit is crucial for a safe install. Structural compatibility is key to keeping everything stable and secure during use.
When installing third row seats, you should:
- Check that the seat kit specifically supports the 5th Gen 4Runner’s mounting points
- Ensure proper alignment with factory brackets to avoid fitment issues
- Consider if additional reinforcement is needed to handle the weight and safety standards
- Look at installation guides or community forums for detailed instructions and tools
- Make sure all mounting hardware is included and matches OEM specs
Following these steps helps ensure a safe, reliable install that maintains your vehicle’s structural integrity.
OEM vs. Aftermarket: Which Third Row Kit Should You Choose?

How do you decide between an OEM third row kit and an aftermarket option for your 4Runner? OEM kits guarantee a precise fit and seamless integration with your vehicle’s structure, backed by manufacturer warranty considerations that offer peace of mind. However, they usually come at a higher price.
Aftermarket options can be more budget-friendly but vary widely in quality and fit. So, it’s essential to research community feedback and verify the supplier’s reputation before making a choice. Both options often require professional installation, which adds to your overall investment.
When weighing OEM kits against aftermarket alternatives, carefully consider warranty coverage and the product’s reliability. Tapping into 4Runner owner experiences can help you find a third row kit that balances quality, support, and compatibility with your specific needs.

Here’s a quick cost comparison to help you decide:

Pros and Cons of Adding a Third Row to Your 4Runner
Adding a third row to your 4Runner can be a game-changer if you often find yourself needing more seats. It’s great for hauling extra passengers, but keep in mind that it might cut into legroom and make the back seats a bit less comfy for those riding there. The installation isn’t exactly a walk in the park either; it can be pretty involved and might cost a pretty penny, especially if you go for original equipment manufacturer (OEM) parts instead of aftermarket options.
Space And Comfort
Three additional seats can transform your 4Runner by increasing its passenger capacity to seven, making it perfect for larger families or group outings. But keep in mind, adding a third row affects space and comfort in a few ways.
When you add the third row, your passenger capacity goes up, but your cargo space shrinks when the seats are in use. Comfort levels in the third row can vary; taller passengers might find it a bit cramped.
There are aftermarket third-row kits designed to help keep your 4Runner looking good and safe. Proper installation is key to maintaining the vehicle’s structure and fitment.
It’s a good idea to test out the space before making a decision to make sure it meets your comfort needs. Finding the right balance between extra seats, usable space, and comfort is crucial to see if a third row suits your lifestyle.
Cost And Complexity
Installing a third row in your 5th Gen 4Runner can cost anywhere from $1,000 to $4,000, depending on whether you choose aftermarket or OEM parts. The price varies a lot based on the quality of the parts and how complex the installation is.
Aftermarket kits are usually more budget-friendly but might not fit as perfectly or look as polished as OEM components. OEM installs often need specific mounting points and structural modifications, which can make the process more complicated and increase labor costs.
Labor for OEM setups can range from $500 to $1,500. It’s important to carefully consider these costs before moving forward. Confirming compatibility with your vehicle’s existing structure and safety features is essential to avoid costly mistakes.
Balancing cost and installation complexity helps you make an informed decision about adding a third row to your 4Runner. Taking the time to evaluate your options will ensure you get the best fit for your needs and budget.

Frequently Asked Questions
How Does Adding a Third Row Affect Cargo Space?
Adding a third row really cuts into your cargo space when the seats are up, going from about 46.3 cubic feet down to roughly 9.0 cubic feet behind the third row.
But if you fold those seats down, you can get close to the original cargo capacity again.
Keep in mind, the extra seats add weight and might limit access to some storage areas.
Will the Third Row Impact Fuel Efficiency?
Yes, adding a third row will impact your 4Runner’s fuel efficiency. The extra weight from the seats and passengers usually drops your mileage by 1-2 miles per gallon, especially in city driving.
While the aerodynamic changes are minor, they can still slightly affect fuel consumption. You can help offset this by keeping your vehicle well-maintained and driving more fuel-efficiently.
These habits can minimize the efficiency loss, even with the added seating capacity.
Are Seat Belts Included With Third Row Kits?
When you add a third row, it’s like weaving a safety net around your passengers. Yes, most third-row kits include seat belts, either integrated or factory-installed, to keep everyone secure.
You shouldn’t have to hunt for these essential components separately. Before buying, double-check the kit specs to ensure the seat belts meet safety standards for both kids and adults.
That way, your new seats won’t just add space—they’ll add peace of mind.
Can the Third Row Seats Fold Flat?
Yes, the third row seats can fold flat in your 4Runner. This feature gives you flexible interior space, letting you switch between extra seating and cargo room quickly.
The seats fold down smoothly and align with the vehicle floor to create a flat surface. You’ll find the 60/40 split design helpful too, as it allows you to fold part of the row while keeping some seats upright for passengers.
Does Adding a Third Row Affect Vehicle Warranty?
Adding a third row can be a double-edged sword when it comes to your vehicle warranty. If you use OEM parts or approved kits installed by certified professionals, you’re less likely to void your warranty.
But modifications that impact safety or the vehicle’s structure might raise some red flags. Always check your warranty details and keep thorough records.
That way, you’ll have a solid defense if warranty questions come up after installation.
Conclusion
Adding a third row to your 5th Gen 4Runner isn’t a simple plug-and-play. It’s more like fitting a puzzle piece that needs careful adjustments.
You’ll need the right mounting points and decide between OEM or aftermarket kits. Be prepared for some modifications along the way.
While it increases seating capacity, it might impact cargo space and comfort.
Weigh the pros and cons carefully. With the right parts and know-how, your upgrade can fit as seamlessly as a glove.
