I'd like to know if anbody has made a decoupling torque arm and telescoping upper link setup for their car. The setup uses a short torque arm (30") that is not mounted to the chassis. But contacts it during acceleration to transmits the axle torque reaction to the frame. Then during deceleration or braking the upper link absorbs the axle torque reaction.

This type of setup allows large amounts of anti-squat improving acceleration and traction coming out of corners.

I beleive global west makes one.

Unbalanced Engineering is also close to finished with one for the 4thgens, it might be easy to adapt to our cars.

Global West makes exactly what you described:

Be ready to drop $600.

Yeah i knew the about the Traklink but i have never really seen a good picture of it. But now that i look a little closer at yes it is.

What i'm really interested in though is making one, for much cheaper.

Awesome thanks i'm going to try and make a version similar to that.

I attached to wrong pic and i didn't have the option to attach the right one when i edited it, huh

You've see the light as many have...

Since your starting from scratch I would suggest using a adjustable double spring torque link or someother type of push-pull bar for your telescoping upper link. So it is adjustable for different springs/shock packages.
The double spring would be nice for split rates between deccel and accel.

Been looking at my GW for years thinking about this, only gone as far as changing the donuts rates.

Good luck, hope you really get this guy right.

Well i'm not quite sure what you mean by adjustable double spring torque link or someother type of push-pull bar can you elaborate. I'm sure its easy to understand but i'm stupid and am not sure if i am picturing it correctly. But i want to try and make something that is easy to build and not complex. Something like this:

You have mail.

exactly how is the tracklink de-coupled??

ME Leigh

If you look at the pic of the Traklink you will see that it has a rubber "spring" in the upper telescoping link. The bottom torque arm is not connected rigidly at the frame, but can move up and down with the pinion. It hits are bar connected to the chassis which limits it movement up. Atleast thats how i think the Traklink works, but i have never really seen one.

WOW! is that a mini ram with DPNI plumed under the manifold? Awesome!

You're right, it doesn't.

What a decoupler does is maintains a solid pinion angle under acceleration (Axle thrust rotation upward is restricted) thus lifting the nose of the car like a normal TQ arm.

Now under braking, the pinion is allowed to rotate downward under hard sudden forces (axle reversing the direction of travel of the wheels slowing, rather than staying ridgid).

Normal tqarms are fine under braking conditions as long as the pavement is smooth and there is not alot of weight transfer prevailant(rear to front weight transfer under hard braking). When you rapidly apply the brakes, the decoupler absords the axle rotaion downward (Like a shock absorber persay) and allows give so that the tires dont instantly lock then release after weight transfer stabilizes. Also when under stabilised braking already- then you hit imperfections in the road (bumps), the tires will not lock and unlock as easily as they glance over the bumps.

Eidt and further note: A decouple will decrease the life of your rear u-joint. So like any racing type part, there is more inspection and replacement necessary to avoid malfunction.
