Hi everybody!

Whats you opinion about self locker (eaton detroit) and air lockers?
which one?
not competition use just hunting....2 axle or enough just one(rear)?

thanks
 
no experience of detroit or any LSD but IMO if you are going to install something like that might as well go full tilt and do it with an air locker, on the rear.
That's what i've done, but not yet used in anger but it's nice that it's there.

Drove a mates with Detroit locker While it did its stuff off road It was still doing its thing when on the road which I did not like.
So go air locker,it is in or it's out. Other option is KAM electro mechanical,no air system needed just two wires up to a dash switch.

Self locker?? You may want to research differential types a little more. To gain an understanding of what they are doing and why.

Ashcroft ATB is probably worth a look.

Both axles will always be better than just one. But cost double. Choice is yours in this regard.

And while Defenders only ever came with open diffs. They are still extremely capable vehciles. So are you sure you have need of any diff upgrades?

I fitted the Ashcroft ATB/Limited sip diffs at the end of 2014 and have noticed a distinct improvement on slippery surfaces, like going uphill on wet grass, climbing slopes which are covered in mud, manure, snow and the like. It was great in the snow earlier this year because I climbed hills easily where you could see that other vehicles with aggressive tyres had skidded and spun their wheels, and you could just sail effortlessly past the point where they had given up. Very reasonably priced, a straight swap with the standard diff centres, don't need any special oil and undetectable on tarmac. I'm not being paid to say this, honestly.

Both axles. In fact after a couple of years I was so pleased with them that I also splashed out on a limited slip centre diff too, so I have the full set.
Also in favour of the Ashcroft units is that I haven't seen anyone online moaning that they've broken one. Whereas Quaife, which used to be the Rolls Royce of limited slip diffs, seems to have yielded a lot of complaints in recent years.

Lockers are good for competition use, or if you do a lot of pay and play activity. But if you're just driving across fields and moorland in the course of a spot of shooting, maybe limited slips will suffice.

If getting only one and for general use. Put it in the back. Although it wouldn’t do any harm in the front.

You can feel them on the road. At least the front one. The same as you can with any fwd car that is fitted with a Torsen style ATB or LSD such as a Honda Integra Type R, MK1 Focus RS, Rover BRM. The steering wheel will snatch a little more and you’ll feel it keeping the wheels in check more.

Off road they are great too. And in most situations will keep all 4 wheels spinning. Whereas open diffs you often only have 2 or 3 wheels spinning at a time.

Full lockers would be better if you are constantly getting wheels high in the air or are rock crawling where you need instant lockup with no wheel slippage at all. But lockers cost more and require manual intervention to use and will reduce your turning circle off road. And they can’t be used on road.

ATB’s can be used all the time and offer improvements on and off road.

In don’t want air lockers....this ATB will good for me!!
 
I fitted a rear lsd from Ashcroft a couple of years back, it really paid off in the snow this year. A great improvement in grip in previous snow . I actually fitted it to help pull boats up slippery slipways .
