OEM Stabilizer are fitted on the Steering Drag Link because of ease of assembly.

The Stabilizer has to be parallel to the Balance Rod on at least one Axis, for optimum performance.

Thanks man. This helps & pictures of your MM540 make it even more clear. Will try this out

PS - have you considered a dropped pitman arm?

Yes, had thought about it but mostly people have mentioned that for lifts of ~4-5", you don't need one.

Also eventually I will get a Hi-steer stuff custom fabricated. That will take some time and till then will do with z-link.

I eventually plan to get something like this 'custom fabricated' (NOT the drag/steering links but the arms)

Anyone has any idea on where I could get this custom fabricated here in Bangalore?

Where are you going to bolt the Hi-Steer Arm/OTT Arm?

I think the caliper mount's is one option. Here are sample pictures:

There are other combinations also -- one that uses the kingpin + caliper mounts:

These are described here:

Installation in detail is mentioned here:

PS: let me talk to Suresh about the fab part. Thanks for pointing out

Try modding this out of the Standard 20 Van Steering/Pull & Push Rod Knuckle Arm

We guy use it as a small hammer

Great mods there shanavaz,It seems we have to find out some real hardcore terrains now!!!!!.I'm eagerly waiting for the beast to be tested here.

Make sure both the ends of the drag link are in the same horizontal plane to minimise bump steer. You can do this by either lowering the pitman arm or raising the knuckles.
Best of luck with this project.

Folks, the work is done 'for now'. I drive it last night for some 2-3 kms ~7:30 pm on mad hosur road traffic. Everything seems normal right now and the ride quality has become better by 'leaps & bounds'. The suspension seems to be 'actually' working now.

Apart from me, the workshop guys have driven it some 10-12 kms and it is spot on.

However, there are several things that still need t be done for 'off-road'. Right now it is good mostly for on-road sedate driving.

Most important is the steering. Will get a new one fabricated soon, Till then it stays like it is right now.

The Gypsy is still at the workshop, some cleaning & some touchups to be done.

Khan,

Not that you will be doing sharp curves at high speeds, but does not the rise in center of gravity affect the stability? Even a sudden turn at 40kmph~ might be enough to at least lift the wheels on the opposite side.

Or is this not at all a concern with this setup?

Good question, but I don't know and I am not spending time unduly worrying about all this. I know what i am getting into has it's own pro's/con's and am ok with all the associated risks it comes with.

It it lifts, so be it.

PS: for Center of Gravity, here is a great article on what it means and what all comes into play when we say 'CG'.

Last night when I visited the Garage, I did not have the camera with me so used the camera of the workshop to take pictures of the Gypsy.

Here are a couple of pictures of me trying to simulate a 'ramp test'

The ramp had a pole and I couldn't go any back further, else the Gypsy would have gone more back without any of the 3 wheels going up in the air or any wheel touching/scraping the fenders/body etc.

And this is what the workshop folks were trying out in the day: easy way to cross medians between main road/service road

Good one Khan bhai. Personally this thread has been highly educative for me.

how about considering longer rear spring shakle. Will make a good difference. Waiting to see a comparison, between a stock gypsy with no sway bars and yours with a lift job. If possible try taking some good shots comparing it with a jeep.

swastikviji · 18th March 2009, 15:57

Khan sir after completing of all mechanicle works at work shop only you had a ramp test i think, if yes please let us know now what is the final GC achieved.
Regarding the ladder yes definitely we need one but not a rigid foot board but we will go for a flexible just like what they have in that army stallion trucks at least for Left side...
