Default Best diff for BEC?

As sierra 3.14 and 3.38 diffs are scarce... what are the other good choices for a bec diff?

Hi you can use a freelander diff if you can fit it to the chassis.

You also need to consider if you want an LSD - 3.62s are available with whereas 3.38 (which I have) and 3.14 hasn't. You can get them retro fitted with a Quaife ATB but that will add about 600.

depends what you want also,

were i live there are loads off twisty windy roads so iv gone for rocket accelleration with a 3.9 but i will be limited on top speed but iff you want to have a better top speed then obviously something like a 3.14 would be good, as for the actual diff the sierra ones arnt that hard to find i saw 5 on a stand at stonley at the weekend for about 40 each though about buying the lot and putting them on ebay could have made a killing lol but the freelander diffs are quite popular and i dont think you would need an awful lot off chassis modification
hope this helps

tilly

Locost solution for a 3.3 or 3.1 LSD is to take the crown wheel and pinion from the diff and swap it into a 3.6 LSD.

a 3.6 LSD is now 150 a 3.3 250 and a 3.1 probably 350, having the crown wheel and pinion professionaly fitted is from 100

So if I can get a 3.62 LSD, take it to somewhere along with my 7" push in shaft 3.38, I can get a 3.38 LSD? Any ideas who will do it?
