Only pro is that it is one piece. Locker is a MUCH better way to go regardless of use.

    A Spool solidly locks the axle shafts togther. Make a turn on a hard surface over 1 mph, and you will break parts. Having FRONT axle lock-outs has no effect on the rear axle.

Never use a spool for a daily driver. Your just asking for trouble.

the street, it had 5:43 gears with a 9" summers bros 35 spline. Never broke anything, but when going up entrance and exit ramps from highways it would wind up then break the back end loose. Did a little stock car driving so I new what to expect, but it could be very disastrous. Go with a good posi... or locker. or check into the airlock dif's to see if it's available for that truck.
