WHere to start...
If you have a buddy with a locker in their rig, try driving it, so you'll know what it'll be like in yours.
I had a lockright, broke it twice.
I had a welded diff., lots of tire squeeling, and it only wants to go straight.
Presently running an ARB, the best of both worlds(in my eyes, well worth the price).
If you have your own air system(most of us do), the price for the locker is only 50-100 more than the detriot.
Also you could check into the new electric locker from trachtech(detriot), it's a limited slip(when unlocked), and a spool when locked. AWESOME idea!!!
The lockrights, and EZ lockers are less expensive...
but you get what you pay for!!
