We install a lot of the BMR trac paks and the Spohn 405 torque arms on Moser 12 bolts. We use loc tite and do not have a problem with the bolts. Bob

The true track is available for the strange rear, bought mine april from moser with the 45 degree pressure angle that strange uses and from what moser told me they will be using the same cut as strange in the future.

Just check true tracks web site if you don't believe me, they have two different 33 spline applications.One with a 45 degree pressure angle, one 33 degree pressure angle.
Its in my car right now, and the reality is moser or strange will cut axles with both angles they just use different standards so they won't be interchangable.

Too bad Strange told me that they wouldn't do that. Otherwise, I would have gone that route, price permiting. Why is Moser cutting teeth for Trachtech (AKA Detroit)? I couldnt find any catalog items for 33deg trutrack, maybe I missed it.

I asked Billingsley about building a strange 12 bolt 33 spline with trutrack differential a few months ago. Nobody ever returned my request, so I figured they had bigger fish to fry and went with Moser through EPP.
I have no doubt that axles can be cut to mate a trutrack in a Strange housing. But with concerns over catalog items, I wasn't about to build a custom rear with either company (Strange or Moser), unless it was set up by Billingsley or other reputable builder.
Bottom line is, if the salesman is non-responsive or doesnt know his product, I'm not about to hand over my hard earned money.

I called the people who make the true trac and was told at this time the ones for the gm 12 bolt style are being cut at a 45* pressure angle. Can anyone find out if this will work in the strange application? This pressure angle was based off of a 33 spline axle.

I found the answer. The spline depth is different between the moser and strange axles. The true trac and strange axles are very loose and will not work properly.

Good job pushinfreight!
I know that John says he has a True Trac in his Strange, but for all practicable purposes, we are limited to Moser if we want a True Trac in a 12-bolt?

After speaking with US Gear, unless the company that makes the true trac is willing to have a version based off of the Strange axles then it will not be the best fit. Unfortunitly I do not have the money to request custom axle so looks like if you want the true trac then moser it is for the 12bolt.

When I called the true track tech line originally in dec 04 the rep told me the only diff available was in 33 degree (old moser) and the 45 degree was going to be available feb march 05. I waited and when available called moser and had them order one from detroit true trac. I spoke to Tony in tech at moser and he told me moser was going to be building all their new axles with a 45 degree angle same as strange.
Also I checked fit of axles in posi's on bench and the both the us gear (original strange posi) and true trac had the same backlash.
The only problem I had was setting up the abs with the new reluctor ring.
I went through the same problems when trying to get answers when making my decision, the guy at detroit true trac was very helpfull.

What problems did you have with abs?
Thanks for the info John, and thanks pfreight.
