2025 GX550 Overtrail 1” Lift (1 Viewer)

[tacoshawn]

I have my 2024 in for its 10K service and saw a 2025 OT in customer delivery. Quick chat confirmed ‘sure take pictures of the front suspension’. While only an inch of lift, it is visible and was noticeable compared to a 2025 Premium also in delivery. I had expected to see a 1/2” or so preload spacer below or above the spring (and within the assembled coil over) to give the 1” lift.

To my surprise, no spacer that I could see.

I was in a bit of a rush to get out of the way. Sorry for poor pictures and my finger in the way on the vehicle picture.

Seems to me that a spring change is the source of the lift. Either as a stiffer spring @ same length or as a longer spring @ same stiffness.

I cannot fathom them changing the structure/travel or suspension mounting points or AVS spring perch modification for a model year change.

I did not look at the rear or crawl under the skid plate. Looking forward to one of you making a skid plate clearance measurement.

I’ll take a similar side profile picture of my OT when I get it back (getting hood flutter TSB).

There is a thread on another forum trying to figure out what springs they are. We should hopefully know soon.

24 vs 25 OT OEM 1” Lift Details via reddit

I doubt there is anything going on other than there aren't a million of both out there yet (particularly the 25) and people are busy with something else, etc. But, I'm happy to see evidence of a master conspiracy to overcharge those of us who want a modest lift :). I’m just being grumpy about...

Those color bars on the springs are generally the Toyota way of marking different springs. If your springs have different markings then it looks like a spring change. Which would be cool as I'd love some 1" lift take offs if they crossed over to my LC-250. I no interested in higher than that personally.

I will check the color bands on my 2024 a week from now when I return from travel. thanks for the tip.

Well no surprise the markings are different. The hard part will be finding a resource that defines the differences. I would expect the LC and GX springs to be different. Larger engine in one, battery in the other. Then add the 1” lift option. Potentially more variables across other trim levels.

Here are the markings from a set of LX-600 take offs that I’m working with on a pet project. Hoping they can offer additional load capacity. Not really looking for a lift.

Do show us your progress in lx section. U must have the no ahc option lucky u

After looking at various specs in spring catalogs it appears that the TNGA trucks rear springs are interchangeable with respect to the bucket sizes. Meaning a given spring is listed to fit all but net a different results obviously based on the vehicle. LC300/LC250/GX550/LX600/Tacoma springs cross over. 2025 4Runner not showing up yet but I'm sure they will be the same. Looking at the published results I'm theorizing the LX600 take offs should give me 1" lift with +/-300lbs of additional weight. That would be perfect but will not know until I try them. And I doubt I try them until I have a set of Slee's front ADS struts in hand. That could take a while. I'll need something to level out the truck. Love my ADS on the 80 so its really hard to deviate to somthing else.

I could try swapping the fronts in as well, little more safety risk disassembling the struts.

There is no way the springs on the lx and lc300 are the same as the gx550. As with the frames control arms and rest of suspension I find that to be very odd. Aic down in Australia dissected most od the underpinnings of the lc300 and lc250 and they were all different. The lc250 has been scaled down as well as the gx550.

Let's use part # C59-819V for argument. Posted for all the 300/250/550. I saw other resources for Tacoma. My only question as this point if there is a different spring on the 600 for any adjustable suspension options. But its very unlikely Toyota changed the frame. That same spring nets a different result on each vehicle but fitment for all imply the spring buckets on the frames/axles are all the same.

Yeah, the same "sized" spring top and bottom, and used across the new platforms, yielding different lift heights based on the model and hybrid or not. They made a lighter one, since the rear end is so light, and the other coils used on the other models lift much differently.

For example, here are the Tacoma rear springs options:
C59-869V - 2.0" lift with stock weight, 1.25" lift with 100lbs constant added weight
C59-817V - 3.0" lift with stock weight, 2.25" lift with 100lbs constant added weight, 1.25" lift with 175-330lbs constant weight added
C59-819V - 2.25" lift with 175-330lbs constant weight added, 1.25" lift with 440-660lbs constant weight added
C59-821V - 2.25" lift with 440-660lbs constant weight added, 1.25" lift with 880-1210lbs constant weight added

The frames on the lc300 and lx600 lx700 are not the same as gx550 and lc250. even the lx700h frame is different than the lx600. The masses have been fooled by toyota. The lc250 and gx do not use anything similar on the underside.. Toyota went out of its way to make sure the 300 series received the beefier and quality components. So there is really nothing really shared. Perhaps the engine may be same but turbos are not and probably more to be discovered down the road.

@crikeymike

You have any idea the difference in rear weight is on a LX600 verse LC-250? I reached out to you a while back looking for increased rear load capacity without really lifting the truck. You had indicated the C59-883V provably wouldn’t be enough for 200lbs of cargo and 200lbs of tongue weight. Buddy of mine just lifted his LX600 so I got to thinking about this OEM swap. Combine it with a set of adjustable height front struts to match the rear ride height.

I have since added some Timbren’s which have given me what I need but at the cost of ride quality.

I don't, sorry.

If the springs were linear spring rate and we knew the specs of the stock springs, then the math could be done to figure out the weights with the springs. Otherwise a scale on the rear end wheels is the only other way.

 

[Azimuth1]

even the lx700h frame is different than the lx600.

What are the differences in the frame between the LX600 and LX700h?
