diff locks

Bob,
If you know how a diff works and how you can quickly become stuck with two wheels (usually diagonally opposite sides) spinning... you will see that there are no disadvantages (apart from the price) on having diff locks.
There are several types but you cannot use a lockrite on the front of a Cruiser because they are full time 4wd and steering is affected.
By far the best way and the easiest on all your components and most expensive is the ARB airlocker, this setup also gives you an air compressor for your tyres etc.
The advantage of air lockers is that if you are travelling on easy terrain you do not turn it on and the car behaves like it did from factory, the lockrites and similar affect steering all the time regardless of wether if its needed or not.
I don't know if the airlockers are available for the front of the independent suspension cruisers but they are certainly available for the beam axles front and rear....
I have a GU patrol with an air locker on the front and the original LSD on the rear and I have found that on steep rutted terrain you just flick the switch and you no longer have to charge at rocks, you just walk them... you no longer need momentum... You just have to be careful to switch it on only when you need it which is almost never unless you are on very difficult terrain.

WILL, thanks for info. I can fit ARB 'Air Locker' to both front and rear. I need to know can they be dissengaged easily when the veihicle has come to a sudden stop on a steep incline and is under severe load? The centre diff takes some time to unlock after it has been disengaged Bob
