🛠️ Member Build Overland Build - 2025 GX550 - Prinsu/CBI, Airdown Gearup, Warn, Baja Designs (1 Viewer)

[Arewethereyet]

Having built both rock crawlers and overland vehicles since the late 2000s, I decided that the GX would be purpose built for overlanding. I picked up the 2025 GX550 OT+ back in May 2025 after waiting about 8 months from initial order/deposit.

Unlike prior rock crawler builds where I sought out the hardest lines and most difficult obstacles, the focus with this build is to access interesting places comfortably and reliably with the competency to tackle unavoidable obstacles without too much effort. Even in stock form, the GX550 OT edition has proven to be quite competent on challenging Colorado trails. On a recent trail trial in stock form, I abused the stock wheels, OT skid plate, and broke two bolts on the OT Rock Sliders, and jostled the rear diff drain bolt causing a very slight seep running Red Cone and Radical Hill outside of Bailey Colorado, but otherwise the GX did not seem to complain too much.

Photo taken before I installed the accessory panels and rear hatch ladder which are now installed. I also removed the Lexus OT Rock Sliders and replaced with the CBI Rock Sliders.

CBI GX550 Front Bumper.

Having attended the Overland Expo in Loveland this past summer, I evaluated a number of front bumper options with two contenders topping out the list; The Dissent Offroad bumper and the CBI GX550 Front Bumper. I chose the CBI front bumper prioritizing the ease of install and requiring less cutting of the front facia while recognizing the approach angle would be less with the CBI vs the Dissent version.

What I didn't fully appreciate is that the CBI bumper makes no allowance for accessing the winch clutch until after I purchased but while waiting for delivery. Had I realized that, I most certainly would have ordered the Dissent bumper instead. Because of the inability to access the clutch without cutting a gapeing whole in the front grill, I was forced to purchase a version of the Warn winch that allowed for remote clutch engagement/disengagement, the Warn Zeon XP 10-S, which has bluetooth capability to operate from a smart phone. I prefer an old school approach to manually disengaging the clutch to run out winch line.

Also, the fit and finish of the CBI front bumper leaves a gap on the extreme corners, almost as though the wings sag out on the ends. I could have shimmed out the wings, but then gaps would have been noticeable near the center piece.

Here are some pics of the CBI bumper installed with the Warn winch:


I have purchased a number of items from CBI/Prinsu over the years and for different vehicles as well as a number of items for this specific build. Until I installed this CBI GX550 bumper, I have been quite pleased with the all the products purchased from CBI. I plan to purchase the Dissent Offroad front bumper to replace this CBI bumper later this year.

Nice build! If you decide to go with portals I would not recommend the Method 703. You would need a more positive offset wheel unless you really like the look of protruding wheels.

Have fun with the build.

Your CBI bumper fitment quality looks like my NYTOP bumper. Same reason for ordering the Dissent bumper which is something I should have done from the beginning. You live, waste money, then learn I guess.

SPOD Bantam Touch Screen Light Control Panel, FitCamX front and rear cameras, iPhone Charger
Here are some interior mods:



















The SPOD control panel is attached to a ProClips (no affiliation with any brands here) Lexus GX Left Dash Mount | ProClip USA. ProClips offers two options for the GX550. I have used many of their mounts over the years and highly recommend the GX Left mount. I have not tried nor am I interested in the center console mount.

The SPOD Bantam controller was taken off my 2019 4Runner build after my son totaled that vehicle. Otherwise, I would have gone with the Garmen light controller option that integrates with Apple CarPlay, a cool idea I may explore in the future.

I am also a huge fan of the FitCamX cameras and have installed these cameras on many of my vehicles. I also installed a wire tap for my radar detector. I have a heavy foot and need the extra help staying out of trouble.

SPOD Bantam Touch Screen Light Control Panel

Looks clean. Which side of firewall did you pull the cable through? Do you need to remove a lot of trims/panels to get the wire pull?

 

[sleepreceptionistbug]

thats too bad to hear on the cbi bumper, thats the one I was looking at but the extreme gaps on the ends is a deal breaker for me.
Otherwise very nice build

I came through on the driver side. I’ll grab some photos and post those so you can see them. If you don’t have an SPOD, go with the Garmin light system, then no wires to run inside the cab. This one here, Garmin PowerSwitch, 6 Gang Compact Digital Switch Box, Requires Compatible Garmin Navigator or Smartphone, Switch Panel for Car SUV UTV ATV Caravan Boat Marine https://www.amazon.com/dp/B08WHGLRMG?tag=lexusgx-20

You can control the lights on an app from your phone or even better through Carplay.

I futzed with the bumper for some time trying to close the gap and can usually figure a way to Jerry rig such things but finally threw in the towel and decided to just upgrade to the Dissent bumper down the road. Buy once, cry once. Now twice.

Have you reached out to CBI? Just curious if they would address it. I’ve seen many of them out there without that big gap. Maybe they had a lapse in quality control.

I’ll reach out and see if there is anything they can do or recommend. Not terribly concerned about. I plan to bash the bumper on the trail and would not be surprised if a hit will bend it up. The bigger design issue is the inability to access the winch clutch. Not a big deal for a winch less install.

I have the CBI with no gaps, my understanding is that the sides have adjustments, I would definitely reach out to CBI. My complaint is there is no way to access the winch

Same. Lack of winch access is reason for prospective buyers to look at other options if they plan to install a winch.

The sagging gaps have not made the list of top 99 problems in my life yet. So, will probably just live with the bumper sag look for now. Honestly, not super noticeable.

For the camera, how is that mounted to the rear window gasket? Would like to do that to my rear view camera, never thought of mounting it like that. Looks very clean.

Here are the gaskets I ordered just for this one job and now will have extra gaskets the rest of my life. Anyone passing through Denver is welcome to have one. https://www.amazon.com/dp/B08BRJF5Z2?tag=lexusgx-20

I used these magnets to attach on the trim and the rear camera, https://www.amazon.com/dp/B0CZLCGVGG?tag=lexusgx-20

The trim piece is easy to remove and drill a whole into to make it look a bit clearner. FWIW, I did the same mod on my daughter's LC250.

Thank you! this is a smart trick because right now i have it stuck to the rear windshield and don't utilize that window.
Edit:

I realized that you have the camera mounted on gasket on the lift gate gasket itself not the lining of the trunk, wondering how managed to run the wires through that

Nice set-up! Was there a significant wind noise increase, primarily around the side panels?

I am planning on the same set up but using the Sherpa Atlas, Baha Onix Light Bar. On another thread I was asking about behind the grill lighting and based, partly on other forum user inputs going with M&R bar lights. Will send pics when done (awaiting parts for assembly).
