I know I have stock 10bolt with 3.42 gears and a Zexel torsen differential. But how do I determine if I have a 2 or 3 series gear set and is the rear end a 3 or 4 channel.


The car has ABS but no sensors on the rear, and don't believe it has TCS.

Is there a serial number on the rearend that can be used to determine the type?

 

M6 car should have a series 3 carrier (stock 3.42) and non-TCS is a 3 channel. Best wishes. WJ.

 

If u have 3.23 or 3.42 its a 3 carier if u got 2.73 or 3.08 u got 2 carier

 

Thanks for the help.
