i have an 84 z28 with a posi (3.73). i think i ***** it out. if anyone has a good aftermarket posi unit in their car can you let me know what it is called, who makes it, and how much is it.

 

i got a detroit locker in my 14bolt. cost $309

what rear end you got? 10bolt?

 

yeah i have the original 10 bolt and i want to keep that rear end.

 

Zexel Torsen from SLP performance parts-$99
Zexel Torsen Heavy Duty from SLP--$(about, i think)299


I got the cheap one, and it's about halfway installed right now (problems getting old carrier out). When it's done, I'll post how it works...in the mean time, I haven't heard anything bad about it.

 

A posi for $100!!!! I might have to get one. I was totally unaware that SLP made anything remotely affordable! Since, you know, the rest of thier stuff is made of gold.

 

The SLP posi is a takeoff, but at $99 it still has to be a very good deal.

The $299 posi was a sale price (it was when I bought mine), was originally listed at $399, but might be cheaper now.

For what its worth, the HD posi uses gears instead of clutches which makes it more durable.

 

the hd is a non rebuildable unit that is what I had in my car .busted spider gears on launch at track took out ring and pinion also.cluch type will just slip.
