Axle/ locker question
I know I'm messing up my nomenclature here, but here the issue. I have the 3.28 or 3.31 open rear end for my 00 F-150. This thing sucks off road and for any kindof power. I'm about to lift the truck 5 inches and put some fender cutouts on it so I can fit 37 inch tires (any excess needed will be made up with body lift). I'm going to need a spool [the LS version of the locker?] and i found a POWERTRAX NO-SLIP. But I need to know my spline count and i was wondering if anybody had used these at all.

Can you find the axle code on the door jamb plate? Or a tag on the axle on one of the bolts holding the back cover on?

A spool is a solid connection between the two sides; it allows NO differentiation at all. If you never intend to drive on dry pavement again, you can install one. Otherwise, it can be very harsh on your drive train. Powertrax no-slip is like a mild locker, and allows more gentle unlocking of the rear end around turns. That's more preferable to a spool.
