a lsd and posi are the same thing. if u say its got a torsen in there then it is a posi. just hope you didnt get stuck with a 2 series posi with a 2:73 ring on there.1997 Camaro LS1 RS

The Torsens are like that. They function as an open rear until it detects slip.
See how many turns of the pinion flange it takes to complete one rotation of the wheel. Appx. 2¾ = 2.73, 3 = 3.08, 3¼ = 3.23, 3½ = 3.421994 Firebird 3.4<br />15.65 @ 86.8<br /><a href=\"http://www.funkz.net/firebird.htm\" target=\"_blank\">funkz.net/firebird</a><br /><a href=\"http://mywebpages.comcast.net/funkz/timeslips.htm\" target=\"_blank\">Timeslips</a>Comment
