Limited slip diffs - Helical

I can buy helical LSD's quite cheaply (comparatively speaking & providing I buy several at a time) but they are only available as standard for the English & Atlas axles, which I assume are only live axles, not independent.

That in itself wouldn't bother me as I want them to use in a chain drive diff, so would make my own bearing carriers etc., but the English is a 22 spline & the Atlas a 16 spline, are these spline setups the same as any later Ford independent axle diffs, in other words, are there any Ford driveshafts with c/v's or pot joints that could be used with those diffs or is all the later stuff completely DIFFerent (see what I did there?

The Westfields used their own cases and special output shafts in their early independent rear ends.

Simple matter of cost, for instance if I can get a few orders for these, then I could do the English diff for 349.95, & the Atlas unit for 384.95, in both cases that's about 40 less than Rally Design have these at, they are the Professional Traction Blackline units, I believe the Quaiffe IB5 is over 600, so that's quite a difference!

But for the diffs to be any use to me I need to have an inboard joint that would be a fit for the spline

Lotus Elan used english diff in lotus housing. So splined output shafts are available. Shame they will cost a lot more than any discount on your diff, don't know of any others.

Found this - may be the same as the ones you are looking at but for a landrover, think they had splined drive shafts as well - http://www.ashcroft-transmissions.co.uk/limited-slip-differentials/ashcroft-atb.html

You might also find some inspiration on here as well - http://chaindrivediff.co.uk/about/home/shop/

Don't actually need any inspiration, we already have our own chain drive diff using the Toyota donor diff, but I was looking for a cheap way of doing a LSD & a supplier coincidentally offered me these diffs.

Just need a way of using one of those diffs with ordinary driveshafts rather than solid halfshafts :s

If anyone is interested in the diffs for English or Atlas setups I could see if we can get a group buy together, if anyone's interested then u2u or email me at russbost at googlemail dot com

Atlas LSD

To be able to do the prices I have listed above I need to get at least 5 orders for whichever diff (if I can get half a dozen combined that would also do it)

The cheapest option is to strip out a Sierra LSD as all the LSD bits are in the housing the crown wheel bolts too.
Yes I know it's a viscous diff but it's the cheapest option and will take Sierra shafts

I would have thought decent second hand Sierra LSD's would be a bit like hen's teeth by now!
