I might have found one ..... went onto "www.car-part.com" and found 2 in OHIO.
Awaiting pictures, spline count and overall dim's from the yard.

Here is my jackshaft

So the Axle that works with this is an auto right?

Thats the one I used... er... modified Blwn!

And yes mark, the axles used is a stock M5 axle for the drivers side, passenger becomes an A4 axle without the stub shaft. (The A4 axles are all the same... the passenger side one just sometimes comes out with a stub shaft stuck to it.)

I am keeping that one, but I think I have another one

i had no idea these were such a wanted item.

I love mine. I am going to try to run one on my v6 swap too (with tg lsd also).

An intermediate shaft can reduce torque steer, if designed right. Though its not needed if the axles are designed right. By that I mean, if the longer axle is made thicker such that both axles experience the same torsional deflection under loading you wont get torque steer. If you make an intermediate shaft setup to prevent torque steer while using the same axles on both sides then the intermediate shaft needs to be a very large diameter such that its torsional deflection in insignificant compared to the axles.

Good luck with your different diameter axles idea... since not only would every car would need a different size axle depending on the torque output of the motor, but every car would need five different size axles to prevent torque steer in all five gears. Not to mention it would take some experimentation with sizes. I have worked at a part store before,... even OEM axles for the same application come in with different sizes... that is one QC check they don't do

You wouldn't need all different size axles, as the torsional deflection of the axles would increase at the same rate with the increase in torque if the axles had equal torsional deflection.

Your right, but what your forgetting is torsional deflection is linear, and we have two seperate sized axles on both side in stock trim. Thereby meaning that if the deflection was the same on both sides, the total deflection across the axle would be a product of the length... which you do not change.

To be honest, while in theory, it would work with enough experimentation, its just easier to fabricate a jackshaft.

Yeah. I have a feeling though that the jack shaft shown isnt thick enough.

Its nearly twice as thick as the axles its connected to.

Well then.

Yup... I have one on the shelf from a H.O quad... and have dealt with a few of the 96-97 j-body ones. The shaft is twice as thick as the stock axle, and what I LOVE about it is that it is bolted to the block and doesn't move with the suspension which worked well with how close my oil drain is to it.

It's a very meaty part.. for the life of me I don't know why GM stopped doing the axle setup this way. When I find another 96-97 in the yard with one I'm pulling it for my current daily driver.

It should work with the Getrag no issues as far as I know... I wonder if there is provision on the eco block to bolt it up like there is on the LD9/Quad/OHV.
