KDSS lean any recommendations in vic ?

[bazzle]

Looking at the thread count they have preloaded the righthand side more effectively making the spring longer on that corner.
That does the same as fitting a longer spring (Or shorter on the other side.)
Its taken a lot of difference though. I would leave it alone if it is within 10mm. You will be chasing rainbows from now on.

I've not had any dramas with the lean since the Dobinsons gear in. I do find if I have parked it on uneven ground and then drive off it will lean but that's how the hydraulic sway bars work. I find a few left to right formula 1 style and it's all good again.

I"ll find some level ground and post some photo's of my measurements.

Hey seeker,

As for my case I don't think it was initially set up correctly from the front spring pre load to the rear air bag sensor spacers ect.
From what I heard statewide have a shaker deck that they can open the KDSS valves slightly and just shake it and shake it. Until it still level and any air is expelled

Airbag man were great with helping sort it out the rear and the front pre load was adjusted photos attached as it is now





It's is great, can't speak more highly about the BP51s on road there smooth yet add a lot of stability and off-road they soak up all the bumps

Any idea what they done to solve it ?

Statewide 4x4 keilor. They can fix lean and also offer lifts for the Kakadu
I have my car booked in for later this month

Thow the installers made some good ground today very happy and close but I'll still have statewide see if they can get it perfect

They had dramas trying to get the rear any higher so I'll have to see how the headlights go
It now Handles very well and has a very good ride on the road


FR 805 FL 800 down 5mm drivers side
RR 825 RL 813 down 12mm drivers side

Fairly close to my factory lean they actually had the rear a few mm better on there floor which may be some what more level than my garage

I purchased a few spare Kakadu rims from a gentleman a while back that mentioned his KDSS lean His installers attempted 3 times to fix it with no luck
He did get it fixed somewhere els.

Lucky I remembered the company and managed to get onto them today, they said they can fix it and have fixed plenty of them even for Toyota and suspension manufactures, 2 week wait thow.

Do you mind saying who that company was?

My lean went haywire some time back (almost a year ago I think) after a high country trip and I went back to the dealer to bleed the system. They got it back to 20mm lean in the end, said that was the best they could do & within factory spec. They did send off a report to Toyota but I never heard any more after that.

I have a 2" lift with Dobinsons coils on the factory TEMS shocks but the shocks have 80,000kms on them now and it might be time for a change. Not sure what I can replace them with but I know I will lose the in-cabin adjustments to the valving offered by the factory shocks.

Hey,

I have in my old notes for Dec2010 build Kakadu front coils, DS = double purple, PS = double brown.

22mm seems a bit large for coil diameter, see all the OEM coil dimensions here;

Your findings suggest there are at least two different OEM coil specs for KDSS.

I think part of the problem with the KDSS lean is the original OEM KDSS coils have not been load-deflection tested, or at least knowledge of these coil rates and free heights is not widely known and may be the cause of some after market KDSS coils being inappropriate.

As the ARB factory is in Melbourne, you should ask ARB to do a load-deflection test on your green/red and pink/blue coils. Then do the same for the ARB coils and let's see how different they are. King Springs do load-deflection coil tests for $5/coil, so it's not big bucks.

Doing this might help clarify how much of the notorious KDSS lean in lifted geometry is because of inappropriate after market coil rates/free heights and/or lack of fluid movement in the KDSS system itself.

Hi Mark,

Your right 22mm seems big now you mention it, I checked them again I was reading the 1 mark on the calipers, the coils are 17mm.

Car is back with them at the moment still waiting to hear what is going on

Ok

Thanks Amts so they are different once the spring has no pre load

Correct. The shock is "assumed" to have identical open and closed lengths both sides. The free length of the coil should vary for KDSS applications.

Very interesting looking at the old front struts the spring lengths are indentical so is the coil thickness

If the coil is still assembled in the shock (thus making a strut assembly), then the length will be exactly the same.

Very interesting looking at the old front struts the spring lengths are indentical so is the coil thickness
From the strut top plate to the longest part of the spring they both measure 345mm long. And cool thickness is 22mm
The only thing that is different is the colour marking on coils

One has a green and red mark the other a pink and blue

The wire diameter can be the same. If the number of coils is also the same, then the only variation left is the free length.

If the wire diameter is different, then it changes the stiffness. So will different number of coils.

I'll jump under tomorrow and have a good look

The BP51 gear isn't made for the Kakadu... I was going to put it in mine but ARB would not do it.

I find with mine that they lean a bit and once you drive they straighten up... if yours I leaning that much I reckon u have GXL Springs..

When I broke my dobo Springs they sent out GXL Springs at 1st. We put those in to get home and the lean was terrible. Once the KDSS Springs went in. No issues...

You could bleed it your self. KDSS is nothing to be scared of. It's just hydraulic sway bars.

If your lean is 50mm then I reckon the springs are wrong

ARB won't do a lot of jobs and they only do there gear, all there work has To be tested ect. all the BP51 kits have car specific mounts for the remote res canisters, not just see where it fits.
They do not make a replacement 2" airbag kit for the rear, airbag man do, They probably weighed up there prospective market vs. time and money to have it all tested ect.

The front is the same as the VX it's just KDSS, part numbers a different there are alot of KDSS Prados with OME gear And they make a KDSS bp51 Kit

GXL fronts are

BP5190002R
BP5190002L

KDSS fronts are

BP5190002R
BP5190004L ( Left is KDSS specific )

Also they are hight adjustable as well so L to R hight TuneIng is not an issue

From what I was told today by the guy who can fix KDSS lean incorrect bleeding can result in the valve dropping in and becoming stuck which can cost $$$$ to replace

[Phs]

The coils will be same thickness.
One will be 5 or 10mm longer free height.

That's ok leave it to them, just thought you might want to spend 10 mins & try it & maybe learn something they don't know lol..... But it might not work lol.....

Alway keen for information, just did not want to try anything prior giving them a chance as the Finger pointing game may start
