- Dive into the world of automotive enhancements with our detailed guide on installing a stage 3 coil conversion kit on your vehicle. Join us in the Metal Tech 4x4 shop as we walk you through each step, from removing the wheels to adjusting the suspension, ensuring your ride gets the upgrade it deserves.
We invented the Coil Conversion Kit years ago, allowing individuals to replace their air bag suspension on GX470 and GX460 with coil springs. Through the addition of coil spring suspension you achieve a smoother ride while eliminating the air bag suspension which is prone to failure.
Air bag suspension tends to leak over time, especially with heavy use. With Metal Tech 4x4's Coil Conversion Kit you get more reliability with your suspension while also adding the ability to further customize your rig. We offer this kit in 3 separate packages so you can choose what components you would like. View our kits below

I was stranded in TN during a road trip after my airbags popped. I installed your kit in 2 hours and was back on the road in no time. My GX470 feels better than new. Great Product !!!!
Happy we could be there when you needed it. I will share a great story with our team. We will keep making more right here in the US!
I bought this kit and put it on my 2009 GX470. It was a great buy. A great way to save some money for future repairs and also improve the performance.
Omg it looks so easy a the dealers just charge so much thank you
If you are comfortable taking tires on and off and have a few basic tools, it's not a hard install to do following along with our video. We also have written instructions on our website. www.metaltech4x4.com and here to provide any support if you need it. We designed, manufacturer and support all our parts right in house here in the US.
This is probably the best instructional video I've ever watched. Fantastic.
*Nice and simple explanations/instructions.*
Amazing
Thanks
Great video, thank you. Are the adjustable shock controls maintained AND the dash error light overridden by removing the two fuses pulled in the video? Or just one - or neither?
To have the truck no longer look for or power the air suspension system you just pull the one relay and the one fuse under the hood. If you removed the adjustable shocks, even just one you will get the flashing error in the center of your dash. This is common when we lift the truck and remove all 4 shocks! To have the truck forget about the adjustable shocks you pull a single fuse inside the truck. This is the 20A TEMS fuse. If you go to our website we have the printed instructions with color photos showing this exact fuse. www.metaltech4x4.com
Great videos - keep them going - especially the GX470 content!
I have the opposite issue here. My previous owner removed the OEM airbags and I now need to re-install them - plus add a 2-3" suspension lift. Any advice / videos on that scenario?
Reversing an airbag delete really depends on how the person did the delete. Did they carefully disconnect the airbag airlines or cut them? Did they leave the air compressor in the truck? Did they use a bolt-in kit or weld spacers onto the axle? There are several variables, and it is best to have a mechanic look at it if you are not sure how or what they did to install the coil springs. There may be more than just unbolting and pulling the coil springs.
@@Metaltech4x4 Thanks guys - I still have the compressor but all the lines from the compressor to the springs were cut and zip-tied. They only pulled the fuse for the air ride to disable it, everything else still in tact.
My main question was about maintaining some type of air springs with factory controls - but also adding a suspension lift. Do I need different air bags (taller)?, what about the leveling sensors? Just looking for any detailed install of a suspension lift that also retains some type of air springs / oem or not. Because that's what I am looking to do - thanks

أين قمت بهذا العمل؟ في الشارقة؟
Purchase this kit for my GX470, one question is when installing the puck I did not see you use washers when using the nylon nut? My kit came with two wahsers for each puck, is it neccessary that we use the washers? I decided to go with a regualr bolt so I could use a regualar 19 mm wrench to screw the bolt tight on top of the puck, I was not having any luck finding an allen wrench to tighten the recessed bolt that came with the kit. I had no prblem puting in the springs because I put the springs in first, then the puck and raised the axle on either end to get the lift that I needed to put each spring in. Thanks
We recently started to include the washers again. However, it works fine w/o. We omitted them for a while since most people were leaving them off due to not wanting to tuck them in during the installation, it can be a tight space. Thank you for running Metal-tech 4x4 parts!

I put this kit on tonight, keeping the original shocks. I pulled the 2 fuses under the hood but my suspension OFF light is flashing. Any ideas? 2007 GX470. Thanks
You may need to pull the TEMS 20A fuse in the dash under the steering wheel. We have photos of the fuse boxes with the fuses and possible relays you may need to pull on our conversion kit install guide on our website located here, step 3.1.

Is a 4-post lift required to perform the conversion? My mobile mechanic was wondering if he could do it for me without a lift.
No auto lift is required. Just some good jack stands and a floor jack is all you need. Using a floor jack ift the truck by the rear differential. Once the tires are off the ground, put jack stands under the frame, lower the frame onto the jackstands but keep the tires off the ground. Next take the tires off, now follow the instructions from here as the floor jack will keep the suspension compressed for you to disconnect the sway bar and shocks, then lower the jack to lower the axle allowing the shocks and swaybar to come free of the frame and the stock airbags to extend to be removed.
Is the metal tech coil conversion compatible with other spring manufacturers or is the form factor of where the spring meets the upper and lower metal tech components not compatible?
Yes, our kit is made to match Toyota specs and will fit with any after market springs for Toyota.
Does this fit the 2007 4Runner?
is it the same electric fuse removal as well?
The Metal-tech 4x4 rear coil conversion kits fit all 4th Gen 4runners, 03-09. The installation and pulling of the relays for dash lights are the same as the GX470 - as seen in our install video. metaltech4x4.com/metal-tech-4x4-gx470-rear-coil-conversion-stage-3-stock-height-w-key-cones/
Hi buddy, isn't ECU give any alarm if you removed AIR SUS fuses ? as there will be no communication between MAIN ECU and SUS ECU ?
Fortunately, the airbag system was never originally designed for the Prado 120. It was the GX470 variant that Toyota/Lexus decided to add it to. Therefore, it's a stand-alone system, not an integrated system. (Like in the GX460). Since it's not integrated once you disable the airbag fuse, taking power from that system, it just turns off in a GX470 or 4th Gen 4 Runner. As opposed to the GX460, where it is integrated, you can't simply unplug it, and the truck forgets about it. In the 460, the main ECU looks for information from the airbag system. This is why, in the GX460, you leave everything plugged in and adjust the rear sensors as needed.
So this is for stock height correct? 2 inch lift/struts wouldn’t work for these coils?
This video shows the airbag conversion and stock-height springs going in. But the install is exactly the same for a lift kit that comes with 2" lift springs.
Quick question. I bought this kit a few years ago and the lower isolator was designed a little differently back then. Since you've redesigned the lower isolator, has the spring ratio changed, or are they the exact same springs from the old stock conversion kit?
The 2.0 CNC machined spring isolator at the axle will not affect the spring ratio. You can run the same stock replacement rear springs. Depending how far back you got the stock rear springs if from us, we updated those to the "Supper stock" by adding a 5% added rate to them to support a little more weight. Same height, just a slightly higher rate spring. To see if you have the Supper stock springs, the model number on them is MT-4010S. metaltech4x4.com/metal-tech-2003-09-lexus-gx470-rear-springs-stock-height-ct/
@@Metaltech4x4 thank you. I think I have the older ones. I have MT-GSJ-4010 10/20 and they seem a little weak. Glad to hear there's been a 5% upgrade.
@@JW-uc2xg The original ones we provided were US Made duplicates of the original Prado 120 rear springs. They worked great for most. However, some GXs just needed a little extra rate. Thus the Supper Stock spring was born.
Just brought the kit. My question is I also brought some new shocks since they must partially come off but I brought regular Bilstein 33-313146 shocks , can I install these with the kit? The factory adjustable shocks cost $1,775 😢
When changing the shocks on a GX470, you can install any shock meant for the same year 4Runner, stock height, or lifted; they all work.
I just stared the job the other day and purchased Billstein 5100 shocks (model #33-313146) for my 2005 GX 470, the old shocks were origianl and I had to hacksaw one off, they definately were shot. I would suggest to just change the shocks while doing this job if you don't know the history of the truck as I brought mine used. Thanks for this soulution for these trucks as the dealer wanted $200 to just look at my truck and tell me what I already knew!@@Metaltech4x4
Can someone clarify or direct me to install instructions for KDSS models? Without visually seeing the process on KDSS, the brief verbal instruction at 3:58 was unclear to me : "if you have KDSS you're not going to disconnect the sway bar. You're going to put the KDSS in bypass". Further explanation, or preferably demonstration is needed for the laymen.
We do not currently have a truck with KDSS to show this process, but here is an explanation.
KDSS trucks have the bypass on the driver's side of the frame bolted to the outside of the frame. Find the black steel shield protecting the KDSS pump, it's also where all the hydraulic lines go in behind. Remove the shield, exposing the pump. At the back of the pump you will see two 10mm hex head bolts pointed outward. These are the bypass valves. Open them up 1.5 to 2.0 turns but not all the way out. The system is now in bypass and you can freely move the KDSS rams with some effort. Once the suspension is installed put the truck on the ground at the new ride height, then close the valves. This will set the new ride hight into the KDSS system.
Is the air suspension just on the rear only?
Yes, just on the rear.
Are the top spring - isolators nescessary?(2.spring) I bought kit without them..
Yes with out them the steel spring rubs on the steel spring perch. Over time this can make quite a bit of noise and will rust. Also Toyota designed the suspension to have the 2nd spring for bottoming out. Do suggest putting a set in.
We have the cones available on our site, metaltech4x4.com/key-cone-rear-spring-upper-isolators-metal-tech-4x4-exclusive-sold-in-pairs/
Do you have to remove the compressor?
The compressor can stay where it's at; no need to remove it once the air system is disabled. It is located up in the driver's side off the frame, tucked just outside the wheel well in the quarter panel. No real gain in removing it. It is not a usable space and does not create any issues when not in use. And no, it's not strong enough to air tires up.
So you left the compressor, sensors, etc installed?
Yes most do leave the now no longer used parts. One can certainly go in and remove them if they want to. But it will not effect anything if left.
Will this kit work with KDSS suspension vehicles?
Yes. This kit works directly with KDSS. This is since we designed all our parts to be interchangeable with the Lexus parts.
Do I have to disable the KDSS before start working on it?
@@aizenitchi2037no, but you do need to open the KDSS valve before starting the conversion. Iron man has a video with a great explanation on how to properly do it
I did all steps but dash massage ( orange triangle) showing ... what should I do?!
Once done with the physical swap out of the airbags to coil springs, for a 470 disable the airbag system and for a 460 you drop the stock sensors down at the frame. Video for the 470 is here: th-cam.com/video/0JPoGp7t1uU/w-d-xo.htmlsi=TV8CaAUwHfUT4JSX
For a GX460 you don't disable the system, you just lower the stock sensors at the frame in the rear. We don't have a video on this but photos in our instructions we include with our kits. Its also on our website for everyone too: metaltech4x4.com/content/GX470-GX460-4Runner%20Rear%20Coil%20Conversion%20Kit%20V3%20(1).pdf?_ga=2.107507202.1263975341.1699287630-1301813325.1647875462
I pulled the relay and the fuse, and my dash light for the air suspension warning would not turn off. I plugged the fuse and relay back in, and it turned off. Hmm?!
I did the rear airbag, delete and remove the front shocks.
Does that mean that I need to pull the air suspension relay and fuse along with the 20 amp TEMS fuse or just the TEMS fuse?
When you remove the OEM Lexus electric shocks/struts, even one, you will usually get a warning light on the dash for SUS. Following our instructions for the airbag relay then the fuses under the dash will take care of this at the time of an airbag swap.
