Locking Diff - air or electric? ... and why?

I'm thinking of getting locking diffs, on the rear at least. Should I be looking at air (ARBs) or electric (Eaton)?

Electric seems to win on cost, ease of instillation and use. What am I missing?

IIRC, you will be limited by your rear axle. If you have a semi-floating axle, I believe, that only the ARB will work. If you have full-floating axle, all options are available to you.

My observation has been electric lockers are very reliable, while air lockers occasionally have leaks. Also, electric lockers are self-contained (moot point if you already have on-board air). But air lockers are available for many more applications.

Why? Where do you go that you need one?

Re: Locking Diff - air or electric? ... and why?

I was advised by John as SMB West (2006) to go with limited slip diff in the rear, and a locker in the front. I don't do heavy duty boulder scrambling, but wanted to get up over ledges, and better pulling power in snow and mud. I wend with the ARB Air Lockers.

I always lusted after an Ox locker, but I don't think they make one that would work for an E350. Cable actuated, but I think they offer electric and air actuated options.

Hell, it doesn't have to be that bad to make a locker a pretty nice thing to have. Sand, snow, gravel, mud... anything that gets the wrong two wheels slipping can mean digging or pulling out where a locker would keep you going.

Re: Locking Diff - air or electric? ... and why?

We chose front lockers on the advice of a friend who was part of the company that brought G-Wagons to the US before Mercedes bought them out. His example was crossing a stream w/rear wheels on slippery rocks and a rocky exit. The added pull we'd get from the front end would help get out.

Went with front and rear ARB. A compressor is a must have so it was an easy decision for me. Nothing exceeds like excess.
