Big Red 97'

How would i go about making the rear end in my 93' a posi-trac so i get both wheels pullin at once? Is there a simple kit that i could buy or what?

i thought they already came with the posi, the clutchs might be gone inside

X2X2X2X2X2 Weld that sucker! It will hold great, but sucks big time on wet pavement when you're in a hurry.

Find a d70 with posi and either swap the rearend or put the posi in your housing.

Your power lock could just be wore out. I thought my truck had an open diff until I pulled the cover. Check the equipment sticker under the hood (if it's still there) or pull the cover and have a look. Could be as easy as new clutches.

both my 89's had open diff. My 93 has a ls and now so does my 89.

I looked at the equipment identification sticker. It is faded badly but i could make out what it said. It says limited slip so i will need to do something to make it posi-trac. And also i was trying to determine what the rear end ratio was. I can make out 3:5 and i believe the last number is 4. Is that correct? is a 3:54 one of the ratios they used in the 1st gen trucks?

Yep 3.54. My 91 is open and it sucks but Im too cheap to do anything about it.

I believe that limited slip and Posi trac are the same thing so you may just need clutches like Wanna said.

he's right limited slip=posi trac just different names for the same thing. Yours is more than likely just wore out and needs new clutches like they said before.
