Hey there, I got the heavy duty rear diff cover / girdle and looks great. There's two bolts that provide support to the bearings at 10' / pounds. My torque wrench doesn't go down that low. I was just going to use my five finger torgue wrench settings but I'm thinking maybe since they bear on the assembly that they need to be perfect.

Thoughts?

I tighten till they engage, back out and coat that portion of the threads with some RTV then tighten back up with slight pressure.

Do you guys use that cover on a stock diff, or only if you've rebuilt the internals for all out racing?

I don’t know if it’s right, but I like to use them with no gasket. Just thin sealer to fill in gaps. Seems to make it more stable in my mind. Just tighten the stops with a wrench till they just get snug. Then tighten jam nut. It’ll pull the stop off the cap slightly. Never had an issue with my 12 bolt with 980 hp and 800 ftlbs.

I’m the same as you on the no gasket. I used the gasket that came with mine and it leaked a tad. When I did a gear change I used silicone like I do on every other diff. No leaks after that. The silicone will take up and fill in any imperfections.
