I hate to say I personally have no clue.

I tried to google that diff, and it looks like it goes on teh FG F1

I am going to try to look some more.

Refer to this link for info on diffs and how they work - http://www.rctek.com/technical/differentials/index.php

I have not run an adjustable diff in my 2WD Harm Bx1 off roader but as an alternative I used a heavy weight silicon diff oil (I think it was 500,000 weight) and it did improve the traction on loose dirt tracks. However as the diff was not sealed the oil would eventually leak out.

I have found that using different weight (and amounts) of silicon diff oil in the diffs of 4WD largescale on and off roaders does make a significant difference to the handling and especially the front end traction.

In an off road, I would recommend a 4 plate self-locking diff. They're basicaly limited slip diffs. When torque is applied to the diff, it locks both axles together. When torque is released, it unlocks allowing you to turn and remain stable giving you the best of both worlds. If you want the best of the best, an Oddified Mag diff from Ian Oddie would be the ticket. It's a completely different design than any other diff out there and works in all conditions in all cars. It works by using Eddy current generated by 2 aluminum plates fitted with magnets to lock up the axles when one is diffing out. It's basicaly an electric motor in reverse used for braking. I've been using one in all my cars for the last 2 seasons and won't use anything else.

Here is a thread I started on RcTek that Mr. Oddie gave a full rundown of the different types of diffs and how they work, and which ones work in different conditions.

I'm running the 4 plate, not only is it progressive it's also adjustable so you can tighten the screws in and lock it up from very little to almost a spool...it offers the best of both worlds, I had it locked pretty tight on my fgbaja and was spinning donuts on my shop concrete floor for 10mins til i got dizzy watching it...cured my needed fix as we've still got snow here and it doesn't go very well in the snow[]

hi thanks for all the info
ive seen one on ebay and its a oddifed competion diff
i emailed the seller asking if its a limited slip diff

I believe it's a 2 plate locking diff, with a 20 degree angle on the locking plates. That's what the 20 + 2 means in one of the buyers questions. Very good diff.
