This is a factory 901 LSD that I am rebuilding for a customer. Now that I have found that Guard transmission has the disks for sale for a good price, these will be much easier to do. This one had a set up for 40% originally, but a broken plate and worn disks made sure that the bias was almost 0. You can see the busted plate in the second pic. Plates are $39 ea at Guard and the disks are $89 ea. At those prices they are the cheapest pieces in the tranny.

Ahhhh..

Rare diffy parts porn good.....

Kinda sucks that regular tranny parts are way more spendy than special option parts...

Cool, I haven't taken my GT LSD apart yet to gaze at it.

Mike, are those parts cheap because they fit a wide spectrum of diffs? What else do those parts cross reference to?

No idea of the fit in other LSDs. The parts are just like motorcycle clutch parts, though.

just curious does the LSD 901 take the usual sweepco trans fluid, do you use an additive?

It does not need swepco at all. Regular dino oil is just fine.

So are you saying it would be a cheap(ish) conversion from standard diff to LSD?

If so... Lets talk about this further...

Um, no. The cost of an LSD, plus the cost of the time to install it correctly is not inexpensive. However, the parts to repair one is not cost prohibitive. The LSD trans I am working on was bought on ebay and sold for $xxxx.00. It wasnt cheap

What I dont get is that Renegade Hybrids rebuilds them for only $1800 (just the LSD!?). I can do it for $300 plus parts and as you see the parts are not $1500.

A few months ago a Torque Biased Diff was $1,895 and a clutch type LSD was $2295 from Guard Transmission. Quaife's were higher. ZF's were hard to find.
