Default Factory LSD

I am wanting a gear lsd instead of a friction pad one, and have found a 2003 Ranger fx4 off-road with a lsd, how do I tell what it is without taking it apart? A special axle code or something?

For that vintage (2003), only the FX4 Level II's came with the Torsen rear LSD (gear driven). The factory Torsen would also be a 31-spline setup.

The 2003 FX4 Off-Roads and all other non-Level II Rangers that had LSD - received the standard 28-spline friction plate Traction-Lok LSD (see below for 2002 FX4 exception).

IIRC Torsen LSD's only came in the following Rangers (all were 31-spline):
2002 FX4 Off-Road's (No lvl II offered that year)
2003-2009 FX4 Level II's
