OME Torsion Bars...?

[BushPig]

Any experiences here with the OME torsion bars for a Gen2/2.5 Montero?

How do they compare to stock?

Is it the same comfort/ride/stiffness, with a height increase? Or are they noticeably stiffer as well as lifting the front end 1.5" ?

Would they pair up well with KYB Monomax shocks?

Thanks!

LOL! Love that the first 2 results are from 4x4wire and the 2nd one is for a Gen II.:26_7_2:

Haha, very amusing....

Except...

None of those links provide the answer to the question that I asked. I asked about OME torsion bars. Those links do not specify that they used OME torsion bars, at least not as far as I can tell. They do talk about a 1.5" lift due to cranking the torsion bars... But were they cranking the OME torsion bars? If so, why? As far as I can tell from the marketing info, the OME torsion bars will provide a 1.5" lift at their static natural position, no cranking required. Of course, I could very well be wrong about that. Which is why I asked the question to begin with.....

Also, does anyone have any info on the part about working well with Monomax's?

I'm no expert or engineer, but I don't think the design of torsion bar suspension allows for the bars to create lift in the sense that swapping springs does in the rear.

You have to "crank" the bars which push the arms down and "lifts" the front. This limits the amount of droop (down travel) in the suspension from the new "lifted" driving position. Here is a link to a picture that may help you visualize what I'm trying to say

I thought the OME torsions allow the truck to sit taller without compromising down travel.

You would be able to get them as firm or soft as you fancy really,depends on how you index them. The way they come from the factory would have the torsion bars in their "sweet spot"(say the the adjustment bolt is wound in halfway for arguments sake). The more it is cranked the firmer it gets i've found. indexing it differently adjusts how high the truck sits at the sweet spot of the torsion bar (with the adjustment bolt still half way in)

(that all makes sense in my head,but I get the feeling it's not that well explained)

I've accommodated for the loss in relative down travel from lifting it by pulling out the front droop stops and sticking a piece of rubber in there to prevent metal on metal. But it means being mindful not to go spinning the front wheel if it is in the air and about to hit the ground as you'll wreck CVs in a heartbeat doing that

I've heard the argument before that cranking the torsion bars simply moves the suspension downward to lift your front end higher but I also believe that cranking them also 'pre-loads' the torsion bars. If it was simply re-setting the start point of the suspension, then the front of the torsion bar would also move/turn. It doesn't.

To me it seems that cranking the bars in back only while the front point doesn't move is twisting them. This is why it seems to me that they're being 'pre-loaded". That also results in less available spring compression from the new starting point which results in less upward travel & a stiffer suspension... unless I'm completely mis-understanding this... which is definitely possible.

I would think that OME's torsion bars are set to provide a higher ride height at their static/midpoint/"zero" position, and then from there, may provide a stiffer spring rate as the bars flex/twist. Is there anyone here that has a set on their truck?

Or, is there another vehicle out there that we could use for comparison? I know the first-gen Mercedes ML's had torsion bars. I'm sure there are others...?

Land Cruiser 100s have torsions. Ton of of people here have them installed.

This is what my brain tells me also, and then I remember that mind numbing rant on 4Wire on this topic, and my brains lurches into a painful cramp, soon followed by a welcome sense of mental paralysis, and I go back to reading Calvin & Hobbes.
