8 3/4" Truetrac

[DLMc]

I just installed a Quick Performance Truetrac in my 74. I see Doctor Diff no longer carries them for the 8 3/4 due to reliability issues. I have installed these in a few Fords and never had an issue. Maybe I should have went with the suregrip. Has anybody had issues with them.

Since I have one of these purchased from Dr Diff to put in the Roadrunner, I'll be following your responses closely!

I went from a 8 1/4 to a 8 3/4. I installed all new bearings and seals. I didn't use green bearing because some people had issues with them. I got my truetrac from quick performance and the forgot to include the spacer that goes between the axle ends so I couldn't adjust the axle end play. I thought it would use the thrust buttons like the factory unit. If I had used the green bearings it doesn't need it. Still waiting on this part. It should have been here yesterday. I was supposed to be headed to Ocala Fl today for the Mopar show/swap meet today. One little part was a big set back.

I run a tru-trac/helical diff behind a 600+ big block, drag radials, hard shifts and lots of street driving and it's been great for coming up on 7 years now. No noise, no skipping or chirping around corners and lays two stripes as long as I stay in the throttle..

They told me about 500-600 mi break on it before any burn outs. Can't wait.

I have a TruTrac in both of my cars, both 741 rear ends. One behind a stout 440. Never an issue with either of them. I'm still running factory taper bearing so I am using the included steel button. 2 nice strips of rubber will be laid down.
