Sway bar options for LX470? (1 Viewer)

[usedname]

Hi folks, couple Qs regarding sway bars.

I want to go to something stiffer to reduce body roll, and I don't care about the possible reduction in articulation.

@ClassyJalopy suggested the LC rear sway bar.

Q1: The bushings will need to change, but do the brackets stay the same? Do I need to take it from a particular MY of the LC?

Q2: Is there anything else I should do at the same time? The end links SEEMED to be pretty intact, but what is the way to tell?

Q3: Other rear sway bar options? Whiteline? TRD?

I just looked this up as well. Whiteline doesn't carry anything specifically for the LX, just for the LC. Seemed like a possible option.

Hmm isn't the stock LX bar already 24mm? Would this really be any stiffer?

EDIT: Or maybe the stock LC bar is 24mm, in which case either the LC or Whiteline would be a similar increase in stiffness.

Rear sway bar - LARGEST size available?

Does anyone know which 100 Series model is equipped with the largest diameter rear sway bar? I know the large dia bar is bad for articulation but I want to reduce some on-road body roll. Perhaps a late-model Land Cruiser or a model from the Middle East comes with a larger bar vs my '01 US bar??

Other apparent alternatives, all 27mm. I believe Whiteline USED to make a 27mm.

Just went out and measured..
Stock LX 23 mm
Stock LC 24 mm

4% increase in diameter...

27mm would be 17% increase in diameter.

But does a 4% increase in diameter equal a 4% increase in stiffness?

No the stiffness is based on the radius squared or something like that.

Here's a handy chart:

https://www.whiteline.com.au/docs/bulletins/Update%20BL-281.pdf

So basically
23 -> 24 = 17% increase in stiffness
23 -> 27 = 90% increase

Now that we put it that way... 90% sounds like alot. Do I really want almost double the stiffness? Might put a lot more wear on the bushings of the rest of the suspension...


Also it appears that the Whiteline 24 mm bar has three points and that if you use the alternative points then it's similar to adding or subtracting 1 mm to the diameter.. meaning that you could potentially choose between a bar that's anywhere from 23-24-25mm in stiffness. Might be a good option. *BUT I can't tell if it will fit the LX - just emailed them.

EDIT: Answer from Whiteline:
"Looking up the BTR94Z, this will fit the 100 Series Landcruiser/LX470"

Im running Whiteline Sway bars, Front+Rear... installed about 10 yrs ago... they were discontinued later (as far as I knew).
Paired with 2" lift, and extended endlinks (trail tailor, etc).

I probably get a bit more wheel lift on obstacles, but I still get through everything I tried... plus on-road handling is nice.
I have a set of stock LC100 swaybars I might experiement with... but my gameplan at the moment, is to setup an way to quick disconnect the front bar before going on trail, and easy re-connect (this is the annoying part).

Nolathane is basically Whiteline painted a different color (red). They are sister brands. I put their sways on the front and rear of my 99 LC about five years ago. I've been very happy with them. Definitly reduced body motions through turns. I'm running them on stock endlinks with no lift.

So do you have a lot of weight on your truck, and are your bars 27mm? Cause on a stock rig I would have thought 27 might be excessively rigid.

Sorry if this is a dumb question, but do you have stock LX torsion bars with AHC removed?

Not me, I have stock LX with AHC. Definitely if AHC was removed I'd also want the LC torsion bars.

Alright another question;

The end of the stock LX bar is rounded and pretty thick - 18 mm. Are the aftermarket bars also this thick, and if not, is that going to cause a problem? Wouldn't they be too loose in the stock end links?

Front bumper, sliders, dual battery, full time. When loaded for camping probably another 400 lbs mostly over the rear. Even unloaded it isn't overly rigid. I think it rides quite nice.

Youre correct, aftermarket bars are not that thick.. and the endlinks are too wide... I use washer to fill in the gap.

 

[usedname]

^ Thanks. I think I'm going for the 24 mm LC rear bar - since everyone says just refreshing the rubber makes a big difference, I figured just going up to LC spec sway bar should give just a little bit more rigidity, and that should be plenty.

I had emailed Whiteline -

Whiteline AU suggested a different bar, but said it was discontinued in the US. Whiteline BTR73 - https://www.whiteline.com.au/product_detail4.php?part_number=BTR73

Whiteline US confirmed that the end-link end of the BTR94Z is narrower than stock, and sent this photo:

I don't think you'll experience much difference with the 1mm increase with the LC rear sway bar. Personally, I'd go with a matched pair (Front and Rear). SuperPro offers both. I tried to find an installed picture of that Whiteline "Three Points" bar but couldn't. I don't know if it is possible using the OE links.

I just bought the SuperPro rear bar, and I'll check back here after I install it.
