1980 320iS 3:91 LSD - $1,300.00 picked up I am in So Cal / Riverside area / 92881


I have been on bimmerforums for years as Oldman


This LSD is rebuilt with:

2 new .083" thick dog ear drive plates
2 new clutch plates
Cleaned and brushed LSD case and internals.

Mods to the LSD include:
The 2 new .083" thick dog ear drive plates, as stock thickness is .076" or so
Addition of 2 extra .020" thick shims, one each side, to add extra internal pressure for high lockup breakaway. Current lockup breakaway torque of LSD is 55 to 58 ft-lbs. See video taken before removing diff from car of breakaway torque on my you tube channel DarylLane.


Rebuild of diff includes - all new seals, diff cover gasket, new front pinion gear bearing and crush sleeve and Red Line 75W90ns full synthetic gear oil. No LSD additive has been added as Red Line LSD additive helps make the clutch slip smoothly, once added you cannot take it out.

Diff test driven in car for 250 miles and runs quiet and smooth.
