inherent torque disorder

usmcsawgunner · June 10th, 2007, 05:21 PM

so my engines got a trickflow upper and lower intake and a cold air kit and an msd dist. and the serpintine belt and reduced pulleys...im about to put 4.30 gears into my car...
the question: should i upgrade to 31 spline axles with the 4.30 i know thats a lot of multiplied torque....i got the stock 28 in there now

Tony_90fox · June 10th, 2007, 05:48 PM

Not unless you really want to or are going to be at the track launching hard on slicks. The 28 spline will hold it, just dont expect to be at the track and not break anything sometime in the future.

usmcsawgunner · June 10th, 2007, 05:51 PM

i kinda want to now since im gonna have the thing apart anyway what brand do you reccomend

Tony_90fox · June 10th, 2007, 05:57 PM

Never done it, so i really dont know. somebody will jump in here i am sure.

usmcsawgunner · June 10th, 2007, 05:58 PM

cool...i was thinking moser but i dunno

Tony_90fox · June 10th, 2007, 06:11 PM

strange is another brand, again, dont know about the quality.

fox trot · June 10th, 2007, 08:56 PM

Ive still got 28s in mine. They are moser but ive never had them break i have torn up a alburn locker but not the axles. I was running slicks then.If your gona replace your locker to id go a head and step up while you got it apart.

usmcsawgunner · June 10th, 2007, 09:14 PM

yea i was looking at the auburn ected electric locker but ive heard from a lot of people that they break easy...whats the difference between LSD and Posi....im lookin for a locker that will lock up real quick but not so much like a spool that i cat make a turn without it squealing the tires....i was thinking abut a detriot locker

fox trot · June 10th, 2007, 09:42 PM

That ected one has got a switch you can turn it on and of the limited slip works just like your factory one would when you turn a coner it will let one wheel spin faster than the other with no tire chirp, when you have it turned on it stays locked up, I ve never heard any body use one but i think you have to drill some holes for the wiring and im no fan of that my self .

usmcsawgunner · June 10th, 2007, 10:02 PM

what about an air locker has anyone put one in for drag racing on here...youd still have to cut a hole right?

fox trot · June 10th, 2007, 10:20 PM

Ya not only that you got to have an air supply to run it I think they use those things on a lot of 4by 4s any of them will do the job for ya, those things are really one of those things that depend on your driving habbits as to how long they last you know. If your trying to pull the wheels off the ground

every time you take off look for failure sooner than if you drive on the street and just looking to make sure there is no one wheel peel durnig the smokey burnout

fox trot · June 10th, 2007, 10:27 PM

Oh ya they have got a set of rebuild kits for the factory one two thats always an optionseems like i saw some one sales a clutch pac that has some upgraded disk that is supposed to better than the one that came in the thing wish i could remeber where i saw them think summit sells them .

ryans88gt · June 11th, 2007, 03:57 PM

If you put 4 clutches in place of the factory 3, remove one of the steels, and shim it up real tight, the factory trac lok is as good as any diff out there. After a fresh rebuild it will chirp the tires when going around a corner just like a spool.

The only problem with it is you have to rebuild it after about every 3000-6000 hard miles and you have to use the friction modifier if you want it to maintain that high level of performance. After about 6k hard miles the performace starts to tail off.

I have the Moser 31 spline axles and the PowerTrax diff. It works great full lock in the straight line and unlocks for turns. I have used a couple of lockers over the years and the Powertrax is by far the quietest I have ever herd. I have only herd it click maybe 3 or 4 times in the 8 months or so I since I installed it. Some lockers I have herd sound like they are gonna come apart and some sound like a 1\2 ratchet.. Buy like you said if you have the extra money do it while it is apart. My next suggestion is to also replace the axle bearings and seals while you are at it. Dont be suprised if in a couple a months the seals start leaking.. They have been wrapped around the stock axles all these years and after stuffing bigger units in there the seals tend to fail shortly there after..

the 1993 gt has stock 28 spline right?

usmcsawgunner · June 11th, 2007, 11:57 PM

how much did you pay for that power trax and the akles?

Yeah you have to tell them what size axles you will be running in the rear and make sure it is not for an open diff. they sent me the wrong one and I had to send it back.. The axles were like 240 or so and the locker was like 450. The unit goes inside where all the trac lock clutches are. You have to take all that out and put it together. Was not that hard..Ring and pinion stay in place during install..

usmcsawgunner · June 12th, 2007, 12:50 AM

nice...so what i read about it on their website sounded like its full lock except thru turns...that cant be..can someone enlighten me? another question....whats the quick way to see if your trac-loc is working properly....besides a burnout?
