I have had ARB air lockers in several vehicles. Had front and rears in my Wrangler TJ. That Jeep was a beast. RE long arm kit with 35" Pro Comps, 12K winch, roller bumpers, aircraft lights, and on and on. Wife hated it so it is long gone.

Richmond doesn't make a lock-rite for my truck and I have never owned one. I only know what I have seen from other owners. I have heard other wheelers we used to run with complain that the axle will sometimes bind and remain locked when it should differentiate freeley. I definitely would not want a ratcheting locker in a front axle. A selectable locker like an Ox Locker or ARB would be my preference. If a front axle locks when you don't want it, you will almost certainly lose steering control of the vehicle.

Lockers are great equipment, but I would suggest a manual locker for the front axle - and somecareful practice. Honestly, if you don't have experience with them, front lockers can be dangerous. More than a few Rubicons have been wrecked by first time 4 wheelers thinking lockers made their $25K Wranglers invincible. I also got to watch a Grand Cherokee with lockers rollover backwards down the quarry at Moody Hill because the vehicle had all the traction in the world and the driver again felt invincible. Traction is not always your friend, especially if you start rolling backwards.

Like many tools, lockers are great, but can be used incorrectly and have equally negative effects.
