does the diffs have seals or do they use silicone?

If you buy a Mag Hytec you dont need silicone. They have O-rings, but they're pricey.......Everyone uses silicone. Make sure you buy the right stuff. Mine has leaked twice now.....However you can buy a roll of gasket and use that. i herd it works pretty good with a bit of silicone to.
Its imparitive that both surfaces are spotless.

Ultragray silicone on the old rear and no leaky. Just change out the cover two weeks ago and great!
