Hey all, I want to fit Arb lockers front and rear to my defender but I am confused on what I need to purchase to have it all installed and running, Basically do I need the Arb manifold to run both lockers front and rear and which lockers do I need, do I need buy the front and rear switch or do it come with compressor? I'm very confused so if someone please help me and point me out what I need to do that be great.

Usually when you buy the diff centres from ARB you also buy the air kit, that includes the special compact compressor/reciever unit with hoses, a wiring harness and the rocker switches for compressor on, rear diff lock and if required front diff lock. ARB sells these compressors and bits for a pretty inflated price but it depends on how much value you put on your time, it can save a fair bit on installation to buy the ARB gear to go with the diff.
One thing I should mention re these "airlockers", they have a reputation for leaking seals on the air actuation ring in side the diff, do a google search on air lockers, here in Australia, their home, they are called the leaky locker, they can empty the oil from your diff by pressurising it, ARB claim to have improved the sealing but I have seen evidence to the contrary.
You are in UK, why not go with Ashcroft air lockers, the same thing manufactured better, I'm about to order an Ashcroft for my Disco1, my mate has one fitted to his, and his son has a bin full of broken parts from ARB units.
The ashcroft has twice as much engagement area on the movable engagement member as the ARB has. You choose .

Think you need to contact the manufacturer, or whoever is supplying the diffs. Those are quite expensive, they should give full instructions and specs.
You will need a compressor, manifold, and air lines. Thats how ARBs work.
The diffs are very good, had several sets. TBH I found the compressor etc. fiddly and unrelaible. Which is why I went to Detroits this time.
Just out of interest, what are you planning to do that needs lockers in both axles?
Thanks for the replies, it's just for off road use at p&p places, is front and rear uprated lockers abit OTT then for what I want them for? I was looking on paddocks website at the Arb kit but when I seen what kit was for sale I just got totally confused and didn't want buy stuff that I wasn't going to use or that was wrong and wasn't going to fit.

Talk to them on the phone. You are spending a lot of money on a specialised product, you deserve a bit of service.
If you just want it for off roading, not worried about slightly heavy steering and bit of clunking on road, you could try a simple mechanical setup, like my Detroit Locker and Tru Trac.
Or go with the Ashcrofts ,like Gazbo suggests. Not had em myself, but many seem satisfied. Ashcroft are helpful, if you phone them, they will give you chapter and verse on the products.

Go for ashcroft if your going to buy an air locker, I have an arb in the rear which leaked a good en until I finally sourced some decent O rings for it thanks to Paul D. A friend of mine brought an ashcroft lsd which doesn't require any compressor ect. We literally fitted it and forget it's there. Kicks in when he needs it and works a treat goes where I go with my air locker
