how about spooling the frount diff i have lockrights in the rear. do thay make one for the frount 
From my research a spool is a bad idea in the front as you won't be able to steer when in 4x4. Also an auto locker will also be difficult. Those ARBS are looking good for the front!
If you do want an auto locker you need a sammi carrier machined.
www.trailtough.com does it.
I wish they had those cable actuated lockers for zuks.
