I've been wobbling back and forth over the lockers for my 4x4 build....I'd like to have cable or air lockers front and rear if I had the coin......Maybe a power trax in the rear and an air locker in the front would work. I have to drive this thing daily on dry pavement so I have to be able to steer it...
Well IMHO...with a full size extra cab truck LWB I would have no problem with a locker in the rear...you will steer fine compared to SWB trucks, LWB are a whole lot more forgiving when lockers are in play.
Ya the cable or air or electric locker in the front would be real nice as an addition later on. It is easy enough to find (come across) a Ltd slip for a D60 so maybe that could be thrown in for cheap who knows.
I have considered the Power Trax and if I am not mistaken they make a soft locker now that has less impact on day to day driving yet still provides a full lockup when needed.
Depending on which axle I end up with ....will ultimately set what locker I'll run. Rockwell = Detroit, D70 = cheapo lok rite. 8.8 = Ltd Slip (have this is ok)
IMHO lockers are best especially with full floating axles because in the rarest of occasions when an axle may break you can still run on one axle if need be!
