Anyone here use this or know anyone?
 

The only time I've heard of people sucessfully using lockers in the front 7.2 diff is when they have swapped in the cast iron diff from a 5 speed ZR2. I've seen 3 or 4 people post up stories who tried it with the aluminum diff and it grenaded on their first trip each time. If you're doing some serious off-roading and really want a front locker then you really should try and find a cast-iron diff.

Thank you
