Hi there,
Can anyone tell me wat weight of diff oil to
put in a Mutant maxx?Tks.

what diffs are you running and talking about? the center diff or diffs at either end? If you have stock maxx diffs on either end forget about silicone diff oil bceause they are not sealed just put grease in there. In the center diff I'd run something pretty thick like 10,000.

I run 30,000 in the center Mp diff, and 10,000 front and 7,000 rear in my SM 1/8 diffs of my JT hybrid.

Tks 4 the reply.
I am running UE 1/8 spider diff,F/R.Center Storm stock diff,
with 13T and 55T for the spur.Wat kind of diff oil wt do u
recon.Tks.

well probably go with 10,000 in the center. then run something like 10,000 front and 5,000 or so in the rear as a baseline.

I run 30,000 in the center of mine because its a monster pirate diff. they take some really thick oil to slow the diff action down.
