What are the spring rates for the LX and LC? I thought the torsion bars and coils were the same rate between LC/LX.

Non-AHC t-bar diameter ~28.87mm
AHC T-bar ~25.5mm
I don't know the spring rates.

Hoser,
I am still using my AHC right now, I got a sahara bar on order, I plan on using AHC until it dies, no rear bumper/swing out just yet until I am ready to scrap AHC completely, having said that should I order the non AHC or the OME TB to compensate for weight of Sahara bar?

Drive it and see how you like it first. My guess is you'll be fine with the stock AHC bars. Just give them a few turns to compensate for the Sahara. If you know somebody who can read your AHC pressure, that would be better.
If you drive a little more aggressive than the average joe or if you want better emergency handling, you might consider the non-AHC t-bars.

What about the rear coils? Are these different in the LX?

Yes..

Any ideas as to how the LX would ride if I changed the torsions and coil springs over to LC parts (but left the AHC in place and functional)?
I'm planning on adding some weight to the car and would like to eliminate some of the swaying and squishy ride feeling of the LX in it's stock form.

Crap..I just bought and received LC AHC springs for my LX. Can anyone conclusively answer what the spec differences are between the two, and if there are differences, will it negatively affect/harm the LX AHC? I guess what I'm trying to ask is, is the AHC system custom-tuned to the respective vehicle (LC or LX)? Or is it safe to put the LC coils in there? I was hoping to knock this out this weekend.
With the LX AHC and LC AHC vehicles being so similar, it's likely they are exactly the same spring and part number. The comparison above was for the LX AHC vs LC non-AHC torsion sprint.
Just to throw another idea out there. Supposedly there is a foreign Diesel AHC Land Cruiser that has stiffer spring rates than the Petrol/Gas AHC Land Cruiser. Those would likely be golden for an armored domestic land cruiser.

Try searching the part number on your AHC LC coils, they may cross reference with LX parts. You could go to one of the many interactive Toyota sites and just enter your P/N see what comes back.
Or even just type the P/N in google

Wouldn't it be more financially efficient to just get ARB or ironman bars instead? I'd imagine even barring cost of the bars themselves, shipping would be killer.

The Lexus rear springs are different than the AHC LC springs but I doubt the difference is that great since the two vehicle are similarly equipped (weight-wise). I wouldn't really worry about it.
Teckis, the HDJ100 has t-bars that not only have a higher spring rate than the UZJ100 but they are physically longer.

The part #'s and prices are different betweent the two brands, LX is more $. In the past, I assumed the $ difference was to see the Lexus name on the box as I wasn't able to get confirmation of any other differences. One LC parts dealer thought the LX springs might be softer to give a "better ride", which seemed plausible.
I searched on a couple on-line parts sites, no spec's listed, just part #'s and price. I've called a few parts guys, they made some assumptions but know one seemed to know conclusively.
Yeah, thanks. I just don't want to be the noob that blew up his AHC because he put the wrong springs in. You don't think each brand would tune their AHC to account for whatever difference is in the springs since they have to work in concert with each other? I was hoping to just swap out the springs, and not have to start adjusting sensors and all. I guess they neutral pressure test I do afterwards will let me know.

The ride would NOT be better with a softer spring when it comes to AHC. The Neutral Pressure has to be right. Just shows how much the dealers know.
Yes, you are right. Checking the Neutral Pressure is the key. Also, if you jack up the rear, take off the shocks and drop the axle, you can pick out the coils and compare the old and new springs. Just watch the brake line and diff breather.
Does ARB or Ironman offer AHC specific torsion bars / springs?
AHC springs are significantly different than non-AHC springs. By as much as 50% difference in spring rate as AHC itself acts as a spring to carry a significant part of the vehicle weight.
Correct. Now we just need to find out what other part is necessary (if at all), to accommodate the longer torsion bar.
