D2 Rear 3 Link System

[Baffle]

Well its been a while, tossed up between grafting an A frame or keeping the Watts link and using another system.
So settled for keeping the watts and designed a 3 link, I also modded the watts so there would be no issues with the extra travel and articulation.
The new Trailing links are crombe moly and a center Heim joint.
The system is smooth and works fantastic with no bush bind or strain.
Pics below.
In the pic of the car articulating, these are 37 in tyres which the sliders were well above the Tyre and the flex had more to go.
This system can bolt on and off quickly with the original arms fitted back on.I ran things past an engineer, time to get it ticked off:angel:

Bloody nice work mate!

If you develop a kit, I hope you don't get left out in the cold, like the Airbag kits.:(
Cheers, Dave.

[Baffle]

Thanks mate, its all done.

[Hendrik]

Great system, looks like you are getting some great results.

Has the onroad dynamics changed much?

[stig0000]

time to make the front work now,,, thats sick

[that_kid]

very interesting indeed! looks like a cheap and simple solution too. Any pics of the hole vehicle on flex? Getting the front end to work with it will be another issue :| Im keen to see it ramped to see how the car behaves

Have you seen the currie joints? Similar to a heim but bigger and have a poly bush in them so i would imagine last a bit longer on the road. And totally greasable and rebuildable in about 5mins flat.

Are they fox 2.0's i see in there too?

Yes, more body roll again as there is no resistance from the trailing arm bushes. there was resistance with the originals, does handle well, I will fab up some disconnects for it i think

time to make the front work now,,, thats sick
Aahh, I did work on the front quite a while ago, I will try to dig up some pics

This heim joint is big and is used in alot of off rd competition trucks, there wont be an issue.
The shocks work great too:D

[Shamo]

Love it! I vote more pics :D

Yes, some more pics please. :cool:

Not doubting its strength more about it being driven on road everyday and flogging out. The comp trucks have the luxury of going oh damn it broke put it on the trailer, or throw this spare one in there. This is not the case in the woolies car park :confused:

The fox are the emulsions i take it? I cant see any resevoirs. What length are they and did you change the upper mounts? Also how did you get them in blue i could only get black :(

Also do you have your rear springs retained top and bottom?

[Baffle]

Nah I promise this joint wont let go at woolies, all the home work has been done, its the bees knees in its class.
The shocks can have the reservoirs on or off and yep the springs are retained top and bottom.

[georgesadlik]

Blue Fox's are the older design. Now the main line is black, but you can still get blues if you order them. After 6mths under your truck i don't think it really matters though. WRT the heims, i have them on the shocks top and bottom and they are fine. It's horses for courses of course.
Baffles design is interesting and we need to see more. Dare i ask, but is the three link Engineered ?

Cheers

[Baffle]

Hey George,
Im lucky and was able to run my design past an engineer, the thumbs up was given for design, strength and no other probs.
I have more steps to take but it all costs dollars.
The system is , Bolt on Bolt off and all components used are structurally engineered beyond the application as well as the mounts attached to the car.
I am wanting it ticked off.

Its all a basket of tricks when any one is wanting a signed off rd worthy high modded car,
Tyres,Lifts.ect.Actually changing a design like this is some what easier to get passed ironically than suspension lifts and tyres:eek:

[that_kid]

Thats what ive decided with my car and the new rear end thats going into it. They'll see the tires, height and other bits and wont even notice the arms have changed...

[micky_b_25]

Any feed back from this setup? I will be doing this within the month. But i plan on using cut radius arms to test before i make trailing arms

[Jazzman]

Can this be used with only a 2" lift? Can you please PM me a price?

Wow flash backs!


After years of stuffing around with these, I ran a triangulated 4 link rear end and have since gone back to the standard rover setup. It has the same springs and shocks as it did with the four link and it still gets the same flex.


Just go to poly bushes all round (Dynamic at chassis end of the arms and Extreme at the dif end) and chop the watts link bracket down and it flex's really well. Mine drops a 35" well below sill height with 11" shocks. simple!

[ozscott]

Why did you go back mate?

Cheers

Hey Toby,

Are the Extreme grade bushes a special order? All they have listed is the Dynamic for the diff to radius arm... Need something that will let me use a bit more of my 12" of travel!

Cheers



I was looking at selling the car for one, but also because the 4 link I had made had a habit of trying to drive the car over under load. So when you were in low and in a high torque situation the rear end would try to drive under itself and pushed it over the passenger side. The geometry was a bit off I think. But it flexed!

I got mine from Lucky8 LLC in the US. They just had them listed on their site. The dynamic ones are a dark blue and poly is bright orange.


They seem to work
