I don't own or drive a GX, or own or drive any other vehicle that needs a suspension lift, but this video was so well put together, I could not help but to watch this sub-30 minute video end to end. For once YouTube actually recommended a video I enjoyed. Thanks guys for the hard work and effort you put in. Aloha🤙🤙

Ok this is the nicest install tutorial I've ever seen. Wow.

[brownersd]

AMAZING video! Love the way this guy goes through step by step, while keeping the video short. It's nice to see that he was being silly through the installation as well. Thank you guys for this!

Watched many videos and you are the only one who adjusted KDSS before starting work. Thanks for the tip!

[aaronlawrence]

You guys are doing some awesome videos that no one else does! 👍🏼

Great video, I was lazy at first and didn’t read all the comments so be sure to do that.

1. Ironman Customer service is top notch, when in doubt just call them
2. Ditto pax front…Jack the driver side to lower pax side or it will fight you
3. Rear shocks come with two extra washers each side, I didn’t need them, verified by customer service. They are there to take up play on bottom mount if needed mine was perfect as is
4) spray your bolts with penetrating oil. If anything seems tight take steps to heat if possible to avoid shearing bolts. I sheared a rear sway bar bolt. This added a half day to the schedule and two trips to the store…wasn’t able to extract after heating multiple times and drilling out and trying extractors. Ended up drilling out and re-tapping. It’s M10x1.25 in case it happens to you, hole size 11/32” or 8.5mm (I think but check yourself)
5) rear pax top shock access is smaller than driver side on my 2015 gx. I opened the access area up a bit with a small cut off wheel/ bending.
6) great wrenches help immensely, def have those
7) for rear shocks, the balancing act as you see in the video is a pain. I found it way easier to use a bungee to hold it up, going through bottom shock hole to the bump stop. Takes a couple tries to get height right but made it super easy
8) pax UCA bolt gets held up on lines in the engine bay, just heads up you might have to fanangle it. I used a pet pry Bar and my hand to move it correctly out. To get back in it was not needed
9) new Panard bar if equipped - be sure to lift the rear and to unload it, will help Versus fighting it. Also ensure the little bends are in right orientation to allow sway bar mount enough clearance.
10) use taller Jack stands, my smaller ones worked but had to use wood to increase height

I just completed my front left corner. Wow, this video makes it easier. These Ironman shocks are absolute beasts. Ok, back to it.

[jasonschmidt]

This is the kind of service you should get when buying $5k suspension system. Unfortunately nobody else does them this nicely. Good job guys, you are setting the standard of what good customer service and support looks like!

[alexjohnson]

That was probably the best how to video ever. Perfect combination of tips and even addresses common obstacles before they happen. Outstanding can’t wait to put mine in.

[richlyons]

Great video! Installed my rears on my 4runner today and would like to add that a small 6mm open ended wrench works much better at holding the top of the strut vs the vise grips.

[mgeiger]

All done. 10 hours doing this solo in my garage - going slowly and methodically. Had one question that was solved with a quick phone call to Ironman. This is the 4th vehicle I have lifted. No others have transformed the ride quality as dramatically as this one - all in positive ways. The truck is PLANTED, but not harsh. Braking is SOLID, with 90% less Nose Dive. Can't wait to hit the trail.

[SuperGunsnstuff]

The least painless install video ive ever seen. Great job. Dont even have a gxor yet but this was entertaining.

[DK_]

wow the amount of effort demonstrating. I am saving this video for my future GX460.

[yotaRE]

Good tutorial, however, the one thing missing in this tutorial is the passenger side front strut. It isn't as easy as the driver front but if you use a floor jack to compress the driver side sway bar (underneath the kdss hydraulic cylinder), that would allow you more than enough room to remove and install the passenger strut.

[erwanfrenchy]

Thanks for all the instructions, you made it on floor like most DIYERS, the kdss valves were not explained on most videos, i own a prado 150 high specs, its pretty much the same car. Thanks bro.

[Broncooffroad]

I just bought a 2018 GX and can’t wait to start my build. Let the saving money begin!

[CoastalGX]

This was a much needed video.I applaud your efforts in creating a tutorial. A big part of me not moving forward on a suspension lift was the lack of info. This gives me the confidence to move forward with a purchase in the near future. I have the tools and now the knowledge. Where can I purchase the UCA?

[Cbv]

Besides the need for extra lighting this is by far the best instructional video I’ve seen! You actually say what freaking tools to use. I never understand when someone takes time to show others how to do something and doesn’t say what freaking tools they used. Now only if I could convince the wife we need to lift the GX... anyone got any ideas?

[FFAdventuresOriginal]

Ordered a stage 2 foam cell pro kit for my 4runner this week, can't wait to get it installed. Great tutorial video, thank you.

[smokey]

Great job at thoroughly explaining what to do step by step! It's appreciated.
Is this suspension a lift kit or is this just to upgrade the suspension components?
