Kudos Khan,
I thought Traction bar was required on front axle more than rear. I think the traction bar on rear is to offset flex in your composite leaf spring.

You desperately need longer shocks in rear which is limiting your articulation. Why not employ front shocks of gypsy which seem to have longer travel at rear? Whats your opinion on this?

Photo #1 has the answer. It is attached there to the frame. It is a metal enclosed PU bush (Wagon R bush) that has been pressed into a metal casing. The traction bar is attached to this bush using shackles. That end of the traction bar also has a threaded bolt which will provide adequate flex during articulation.

I agree. Only after getting this done & driving the Gypsy I realize the importance of the traction bar. I must say that I have been plain lucky to have got away without damaging my axles without the traction bar. In a high torque setup it is a disaster waiting to happen without a traction bar.

How is the articulation? Some Spidey pics please
I did not get enough opportunities to test the articulation but whatever little I tried, the articulation was ok. No major hindrance to articulation due to the traction bar.

I don't know if T-bar is required in the front BUT for sure it is almost necessary in the rear if you want a reliableSPoA setup. Composite springs are not that much of a factor.

One thing at a time.. Longer shocks will come one day

Ah, so it does!

Need to have a closer look one of these days.

Apart from there - noticed that you posted you have Spidey's seats up for grab for any takers. So, what is in there now? Upgraded the seats to something special?

Shocks for the FRONT.

~26" extended and ~16" compressed, giving a total travel of ~10". That should give some SOLID articulation.

Other tid-bits about these shocks:
  • Specifically engineered for offroad and lifted vehicles.
  • 14mm Hardened Chromed piston rod
  • One piece alloy rod guide & seal system
  • 46mm piston with self-adjusting digressive valving
  • One piece seamless monotube shock body
  • Patented nitrogen chamber and floating dividing piston
  • 360psi gas pressure
This will require some fabrication to be done... So, the season for work on the Gypsy starts again

Default Upside down traction bars?

K_S : Was looking at the pictures of the Gypsy at the 09 Noida Autocross and I felt there was something amiss with the traction bars here: http://www.team-bhp.com/forum/attach...-photo0915.jpg

Could you please have a look at this and the other pics ( http://www.team-bhp.com/forum/indian...g-noida-3.html (Autocross 2009 Confirmed @ G.Noida)) of the vehicle and clarify?

Also the mounting points would drastically reduce ground clearance of the vehicle?

The Gypsy belongs to a NIOC offroader. It has been prepared by Raj Kapoor. 35" tyres sir with custom made shocks by bilstein, custom fibreglass fenders, front & rear auto lockers, the list can go on and on. It is a monster!!

That orange bars are not traction bars but the links/arms for coil over. In this Gypsy, leafs have been removed and coil over done. So these orange bars hold the gypsy from chassis to axle (a very simple explanation).

Yes, it's a beautiful monster.
PS: I don't think it has front lockers as yet . That is in the TBD list, as per Arjun.

Found this in some site. Hope this helps in better understanding coil over

Oh, forgot to update this thread. Here is how the bilstien's look on the Gypsy. Had got them installed a day prior to the Bangalore Annual OTR.

As expected, the articulation is GREAT now and so is the ride quality at the front. No more bone jarring feedback from the suspension setup. Can fly over potholes/speedbrakers without any thought..

Now need to find good stable leafs for the front as the CFL's are no good for the front. Will now put on the EMU leafs up front and see how it works out.

Yeah this man is totally nuts! he started and completed this mod "couple of hours" before a major OTR!

Khan saab i think you should add rubber beading around the bilstiens as Rudy suggested, why waste that dust caps.

Hey, so far it was as reliable as any other 4x4, only the front CF is giving trouble now. Then again its an R&D phase with that. I think the steering lateral force is too much + SPOA.

But the combo of shock and cf is deadly no more thunk's when you go over something, front is so much improved. Its the rear that tries to overtake you now

I did not follow this either. In simpler words please? You mean the rear jumps more than the front?

What to do man, knowing the laziness, this would not get done otherwise..

Yes. has to be done.. lots of small patchup things pending. I couldn't ask them to do this at 12.30 in the night that day

Agree. I was devastated/frustrated beyond imagination when I saw that front CFL crack. Not much fun, if the thing is not reliable.. Don;t worry saaarr, it will get there. All part of the game..

touch wood.. apart from the front CFL issue, all other mods have been SUPER reliable till now and well tested over time. Even the front CFL are experimental (and the dealer/manufacturer had clearly stated so) but still you feel bad when you have to baby-sit the vehicle during the OTR and not push it.

Oh, i love that feeling. Believe me, it's kind of "Priceless". Being in a Gypsy, jumping over speedbrakers and no more bone jarring 'thunks'..

The damping by bilstien is working very nicely..

Yes, the rear jumps more than front -- stock shocks in rear till now..
