Diff ID

Post by Jimmer84 »

I have a diff like this one in the rally car. it is starting to break away easier than usual, so I need to rebuild it, but I have no idea what kind it is. It is a R180. It kinda looks like a Nismo LSD, but says LOM6 on it like a precision gear lsd. It is a clutch type 4 pinion lsd. Any help?

id guess that the clutches for an R180 diff are going to be similiar(in size, not quality) & readily avail... :?


be sure to document it!!! i will be doing this eventually.

So I contacted Precision Gear, and they said that my diff is not a precision gear diff. Any more ideas? Where can I get different clutches for it?

Are you sure it's not a Nissan/Fuji heavy industries part? When purenissan/calmini was selling them they claimed "This is factory stuff!" If it's factory, then...

Nissan Part # Quantity Description
38420-U3010 1 R180 limited slip differential, 4 pinion type, 45 ft-lb break away torque. Designed
for 115mm ID differentials. Side gear axle splines are 26mm x 25t.
38433-RS610 4 R180 LSD replacement part; friction disc 1.9mm.
38434-E4610 4 R180 LSD replacement part; screw.
38435-E4610 2 R180 LSD replacement part; spring plate 1.7mm.
38436-E4610 2 R180 LSD replacement part; spring disc 1.7mm.

Edit: actually, since this is for the later style circlip mounting LSD, they might be different. Scroll down on this page to the table:

Check with Chad @ Chico Nissan, or Riley at Lynchburg Nissan. It is always interesting what a 510-friendly parts department can find in the Nissan USA warehouses.

That's because it's an R180. It's definitely a normal R180 LSD, not a phony grip.
