Peloquin diff and Torsen TBD (similarities?)

[Sodo]

That has been offered before, maybe a different company.
IIRC it was much much less $$ but was likely cheesier.

That looks like a nice product, but how much torque do you think can be transferred across that lubricated 'circle' where the springs mash it against the side gears?

Probably a little.

Look at a real clutch-type LSD that has a series of clutches, friction material, requiring enhanced lubrication for optimal performance (that squishes out of the way at peril to your gears/bearings!).

And the force comes from an arrangement of "ramps" that produce more force as torque increases,
not just the constant-force of springs.

It's probably helps a little.
$379/$1500= 25%
I highly doubt it's even 25% of a $1500 Peloquin.
Perhaps better than nothing but I doubt its better than your parking brake lever.

I wonder if the preload will cause issues when trying to lock the diff up.

Also, you must machine some clearance on one side of each of the internal gears inside the diff itself (spider gears).

Are those gears still available new? (just incase I'd want to revert it back to stock)

Thanks!

I see now . The Traction Concepts spring-loaded LSD block itself replaces item 11 on a standard open diff. The syncro locker (shown below) has the 2 additional holes on that part, as well as the two extra shafts (#17), & 2 more gears (#13). That LSD block only works with 2 spider gears inside the diff, as it looks like a factory locker has 4 gears in there, if i'm reading that right...

& a 091 open diff (for reference) The block replaces item 5 in the illustration below, and puts a spring load on the two spider gears (item 4).

I would definitely try that TC LSD block thing on my lowered '85 if I still had it...

Thanks again Sodo
