TRD Pro (2019+) Roof Rack Install – 5th Gen 4Runner

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

TRD Pro (2019+) Roof Rack Swap and Installation Guide – Parts List and Overview For the 5th Gen 4Runner

Back in 2019, Toyota paid tribute to the FJ Cruiser by incorporating its roof rack onto the TRD Pro 4Runner. The basket style roof rack is definitely a departure from the rails and crossbars roof rack from past 4Runnners.

There is some discussion on how this rack looks; some people don’t like it and some do. I fall under the latter category, and when I came across one in my area, I jumped on the opportunity.

A used TRD Pro Roof Rack can usually be found for sale on Facebook Marketplace/Groups, Offer Up, Vilmont Market, etc. You can also buy a new Pro Rack (PT278-89190) from the dealership, however, this will be the more expensive option.

Buying a Used Roof Rack

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

When buying a used TRD Pro Roof Rack, I highly recommend getting a hardware kit (PT278-35130-HW) since the foam and fiber washers will most likely need to be replaced. My recommendation is from the FJ roof rack. It is the same hardware as the TRD Pro Hardware Kit (PT278-89190-HW) at a fraction of the cost (~$20 vs. ~$102), plus it comes with extra screws and washers. Also make sure you are getting 4 roof Brackets (63185-42020), if not you’ll have to order them from the dealer.

Tools & Materials:

Step 1. Remove Stock Roof Rack & Clean Roof

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Start by removing the 4 roof rail plastic caps. Once the caps have been removed, use a 12mm socket to remove the 8 screws holding the roof rails to the roof. Remove the roof rails and clean the area where the rail base previously contacted the roof.

Step 2. Install Brackets

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Install 4 brackets (63185-42020) at each of the roof mounting points. The brackets should be positioned so that the tabs are facing towards the doors.

Step 3. Prep Roof Rack Install

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Before lifting the roof rack on top of the roof of the 4Runner, I recommend taking 3 of the crossbars off to reduce weight. Keep one crossbar attached towards the front of the roof rack to maintain rigidity when the roof rack is lifted over the vehicle.

Step 5. Apply Foam Washers

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Clean the spools (metallic bushing) with some isopropyl alcohol.

Peel off the adhesive backing on the foam washers and adhere the foam washers onto the bottom surface of the spools. You’ll have to do this for each of the 8 spools. Take the time to do this right since the foam washer will act as a water barrier once it is sandwiched between the spools and brackets.

Step 6. Position Roof Rack On Top Of 4Runner

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

With the help of a friend, lift the rack over the vehicle. This can be done by a single person but I recommend putting a towel down on the other side to prevent damaging the roof. Another option is to separate the left and right half of the rack by completely removing 2 M5 screws from the connector.

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Next, loosen the 2 thumb screws located on the crossbar (see photo on the left above).

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Loosen the 4 M5 (T25) screws on the connector. Then, position the rack so that the holes align between the roof rack and the roof. Make sure that the foam washers are not blocking the hole openings.

Step 7. Install Roof Rack

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Install the M8 (T40) screws and fiber washers by hand in all 8 locations (front and rear end support). This is only to start the thread, do not fully tighten at this point.

Note: Do not forget the fiber washers; they seal the gaps between the spools and screws to prevent water from getting in.

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Make sure the front and rear end support sits on the roof and follows the roof’s contour.

Begin tightening the 4 rear end support screws first then move onto the 4 front end support screws. Check and verify that all end supports are properly seated onto the roof.

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

Torque the screws to 13 lb-ft (18.0 Nm +/- 3Nm). Starting again with the 4 rear end support screws first. Alternate between the screws when torquing to draw down the supports evenly.

Tighten the 4 M5 (T25) screws on the connector, torque to 35 lb-in (4 Nm) or just hand tight.

Step 8. Install Crossbars

Note the crossbars are orientation specific. All crossbars will have to be installed with the arrow facing “FORWARD” and the thumbwheel knobs facing up.

Double-check and make sure the lower clamps are on the correct side (LH vs. RH). If the clamps are on the wrong side, they will not be able to be installed. Separate the lower clamps along with the thumbwheel knobs to their respected side and place them on top of the roof, they will have to be separated in order for the crossbars to fit over the rails.

Step 9. Reposition Crossbars To Finish Up!

TRD Pro (2019+) Roof Rack Installation Guide & Overview For the 5th Gen 4Runner

The last step is to remove the lower clamps from the crossbars and then position the crossbars between the vertical rail sections.

After that, you’ll need to loosen the inner thumbwheel knobs to adjust the width of the crossbars as they are positioned in place. Lastly, attach the lower clamps with the thumbwheel knobs on both sides, and then center the crossbars and tighten the inner thumbwheel knobs.

Final Thoughts

The install on the TRD Pro Rack is pretty straightforward and it took me about an hour and a half to do.

When installing this rack, one of the main concerns I had was a leaking roof. I contemplated reusing the old hardware, but after looking it over, I decided for peace of mind. Replacing all the hardware was the way to go, and given the low cost of the kit, it was a no-brainer. I can happily say after multiple Costco car washes I have zero leaks!

I’ve used this rack a few times for hauling, camping, and climbing gear and it has worked out great for me and definitely freed up the much-needed trunk space!

The TRD Pro Roof Rack is a good looking rack in my opinion and if one comes across you at a great price, I would highly recommend picking it up!

Updates

After having the rack installed for a while I’ve decided to mount my Pelican Storm case to the top for some extra weatherproof storage. I’ve seen some rail bolt combo similar to how roof top tents are mounted but didn’t like the look plus taking it on and off seemed like a pain. I wanted something more stream lined and can be removed with relative ease.

Here is what I’ve came up with:

1/4-20 Rivet Nuts installed in crossbars.

Thumb screws to hold the Pelican case to the crossbars.

All set for more gear storage!

Hi, Jensen. Just wanted to say thanks for posting these thorough instructions. I work at a body shop & our local Toyota dealership sent a brand new 4Runner over to us to have the roof rack reinstalled after a poorly done first attempt at the area distribution center that resulted in a leak down the driver side B-pillar. With your instructions & insights the job was a breeze for us. 100% agree with your recommendation to go with all new hardware.
Thanks again.

Nice setup with the Pelican Case. Would you be able to provide the parts used to get it mounted? Also, a bit of a step by step, did you drill the crossbar to install the rivet nut?

What size is this pelican case? I am thinking about installing a low profile pelican gun case on top of my 2020 t4r trd pro for extra storage. This one looks great!

Jensen, thanks for the instructions. I do not remember my brand new OEM Toyota mounting brackets having a rubber gasket underneath. I think they were bare metal. Also, are your support pads made of plastic or rubber?

Wondering how how your install is holding up to leaks. I did the rack install per your instructions but I am really paranoid about leaks and feel uncomfortable not using a sealant. Just hoping that the bracket and washer setup works.

Really nice set up with the pelican case! How has it held up? Also can you do a write up of how you drilled holes and modifies your cross bar for the storage attachment? Thanks!

The hardware kit you linked…..does it come with the adhesive foam washers? Sorry if that is a dumb question, but Toyota does not mention what comes in the kit. If the used TRD pro rack I am buying has the mounting brackets, does the kit you linked have everything else?

I was also going between Gobi and TRD Pro. When I bought my 4runner, the guy behind me was there to pick his wife’s up, and he was selling his TRD pro rack for $300. Seemed like a no brainer to me.

The Pelican Case mounting is really smart! Do you think the nuts are strong enough to mount a high lift jack? Thanks 🙏

My Dealer brought in PT278-0C200-CB. The were 34-3/4″ long. I find that listed as 4Runner and Tundra. Too short for the Sequoia

I spaced out the 3 bars that came with. It looks better but I’d still like 1 or 2 more

Is this PT278-35180-AA? It will be worth it to get the ends. I have an extra cross bar from my 2018 TRD Sport. I’ll see if it is the same. then hopefully i just need to put in some rivet nuts. thanks

I just got a Sequoia TRD Pro and the roof rack looks like identical parts. I’d like to add more cross bars. Any help with where to buy them? My dealer is stumped.

The bars are 38-11/32″ or 973mm wide measuring across the bow of the top surface. There is a nut insert in the top near each end.I don’t see a part number on the ends, just an L and R.
Thanks

My local dealer finally got a crossbar kit that fit. It looks better but I still want the look of the 4Runner TRD Pro rack so I’m ordering 2 more bars. 6 Bars will give me the same spacing as the 4Runner. I’ll post a picture when it’s done. Thanks for your help

Do you have a part number on the crossbars? I have been trying to get an extra bar or two for my Sequoia too but Toyota has not been able to help.

Thanks for the write up. I see its listed as 2019+. Did they change where the holes are after 19? Will this (in theory) work on all 5th gen 4runners to replace the factory rack?

Excellent write-up. Thank you. I’m of the same opinion and recently installed one. I used the new FJ hardware kit but did not use the brackets. My understanding was that the brackets are for use when you are deleting a rack – so the rubber trim has something to snap onto, but now I’m thinking I should have used them. Do you know for sure if they are necessary? Everything seems to be fine and the spools seem to be very tight against the roof (installed new foam washers as well). Thanks!

I installed the brackets today and they were definitely necessary. Not only do they clearly act as the main water seal but they enable you to apply the proper torque to the bolts. I noticed the front foam washers were barely compressed and the rears were completely destroyed, so in both cases probably not doing their job. I’m really glad I found your blog!

I went ahead and ordered the brackets. Otherwise I’d just obsess about it and drive myself nuts. lol. If I ended up with a leaky roof later I’d kick myself. Also had to source some new self adhesive foam washers – I was able to find some that will work. Thanks again!

Thanks. I’ll do that yeah. I noticed that when I installed it – that the old foam washers were completely compressed and the spool basically cut into them.

In the endless debate on RTT or no RTT, I’ve elected to keep my pro roof rack, and honestly it works fine for me. I got a $60 roof bag on Amazon and keep all non-essentials up there when I’m on the trail. Putting more weight on a bigger roof rack just feels like too much weight to me (at least with the current Pro Fox suspension).

Hi Robert, Are you saying that you did install an RTT on your pro roof rack? If so how heavy is it? Easy installation? Wondering about this myself so any advice would be great for my and my pro rack

No RTT on pro roof rack. Not only can it not support that kind of weight according to the manufacturer, your’s truck’s height and look would border on the absurd. Do not try.

So I ended up calling Toyota directly, had to call my dealership and talk with the parts department, and they confirmed that the rack is sturdy enough for an RTT. It can hold 300lbs dynamic, and 600lbs static. As far as looks, it doesn’t really bother me.

If this is true, and you go this route, I demand you to do a write-up on this website!!
