i dont have a posi rear, but was wondering if it is possible to convert my rear to a posi? and what would i need? assuming this is possible..thanks in advance

 

also how can i tell which gears i have? also, can i change just the gears out if i wish? im assuming it might have a 2 something ratio...i want 3.73's after i get enough money to spice up my engine...is it possible to switch them? i know it will screw up my speedometer

 

You can check your stock gear ratio with the tables in the Tech Data section. And unless you're a skilled mechanic with the knowledge and tools, I recommend taking your car in to a shop for a gear/posi install. Thats what I plan to do. SLP has an OEM posi unit for $100, and I'm currently looking for decently priced 3.73 gears.

Estimated cost to install gears is $300 from what I hear.
*** this is going to be so expensive, but worth it.
I'm hearing 3-4 tenths off an ET from 2.73 open to 3.73 posi

 

The installation of a Limited Slip (aka posi) all depends on what rear you now have. For example a 10-bolt 2-series 26 spline axles=no aftermarket products. So you have to know what you have first before you start looking for parts.

 

Will a shop usually recalibrate your spedo after the gears are installed... or is this something that I have to look into if I do this?
