True Trac rear end ??

[SY2455]

I went to a wrecking yard last Sat and found a 1993 - 4 door Jimmy 4X4 with a True Trac rear end in it.

The rear looks like it had billet axles in it as well do to the axle flange had the machine flat face on it. Has anyone heard or know anyone that has ran this rear end? Will the Jimmy Rear fit a Syclone :dunno: ? I was thinking of going back and checking the gear ratio.

Get it! It would be much better than our rear!

i don't see why it wouldn't fit if it was a regular jimmy and not a zr2 or anything

This rear didnt come in any factory vehicles right?

Nope. It's suppose to be similar to a Zexel Torsen LSD. It doesn't provide 100% lockup, from what I've read.

I Was Going To Use The True Trac In My Sy But It Was Back Ordered Thru Summit, So I Went With Carbon Posi Unit, I'd Def Snatch It Up And Use It Or Sell It.

The TrueTrac is a niece piece.

Def check gear ratios, since somebody obviously had it put in, it's possible the ratios were swapped (front and rear) to something other than what the glovebox plate would indicate.

It certainly is a better diff than the factory Gov-Loc which isn't a limited slip. More of a limited spin, by design.

The biggest head ache you're going to run into is the rear wheel sensors, if you're still running ABS. The 93 doesn't have any.

Not to hijack this thread but reading this reply reminded me of a question I had.
Do the SyTy's have separate wheel speed sensors on each rear wheel, as opposed to one sensor at the output of the trans. like most GM trucks?

Yes you are correct each wheel has its own sensor:tdown: .
