Thread: Diff ratio

Kev, if you are planning to retrofit the e-diff then you will be buying a whole new "e-diff" anyway so the discussion on fitting the 3.7 ring and pinion into the 3.54 housing is moot.

If you haven't yet, have a read of this to get an idea of what you are up for:

Yep seen that write up, that's where I got the idea

Still have to do the front diff though don't I?......don't think 3.54 at one end and 3.7 at the other will go too well.......

Getting the mechanical will be ok, it's the wiring that will be fun. It's just a concept at the moment, I saw an e diff on eBay with the 3.7 ratio, that's what made me think of the ratio change.

Cheers
Kev

quite right! wasn't thinking about he front end when I wrote that!

Yeah, I knew what you meant though.....

If you're going to all this trouble, think about fitting an ARB locker to the front with the 3.7 ratio.

Baz.

I have thought about the traditional lockers but I haven't had the car long enough to evaluate its ability. From reading various forums, there appears to be some who like normal lockers and those that say that it is better to let the terrain system work like it should and a locker would interfere with this. As I said, I have no opinion on this because I haven't really looked at it or spoken in depth to anyone that has a locker and what effect if any it has on the cars systems.

If I need to rebuild either end that's what I'll be fitting. Got the compressor.
(Standard ratio though)

I wonder if unseenone (whom hasn't been here a while) does a kit to do the conversion? As North America have mostly V8s, they should be readily available.
