Gasket for 8 3/4 Differential- LubeLocker for Chrysler 8.75" Differential Gasket - LLR-C875

Anyone ever used one of these? Thoughts?

Kind of costly at $25 plus on Amazon, but maybe a good seal and forever?

I’m using the pink gasket from Dr.Diff. Good so far,have to see if it’s really re-usable when I replace gears.

That may work, I don't know. At a glance, it reminds me of those plastic automatic transmission pan gaskets...the ones with the rubber ribs in them for sealing. They seemed to work well.
I use this:

This sealant seems to be the best that I have ever used. NO black, ultra gray, blue, orange or red RTV beats it.
I used to use gaskets on the 8 3/4" 3rd member but once I switched to just "The Right Stuff," My leaks have stopped.

I just use a cheap paper with a very thin layer of black rtv on both sides.... never had a leak

I have never had a leak using just a Felpro/OEM dry gasket. Skipping the gasket does slightly misalign the axles.

Paper and aviation gasket sealer for me. I don't do leaks..

Tucson Differential turned me on to this as they use no gaskets at all.

That's a Superformance gasket I think. Supposed to be good stuff! I don't know if it will be reusable. (I bought a couple pairs of superformance valve cover gaskets for my bbm FOUR bolt covers, but I haven't tried em yet.)

"The Right Stuff" comes in gray too. Good stuff.

Excellent gasket, great if changing rear ends frequently. But a couple of cautions... 1.Be sure the mounting surface is totally clean on the diff and housing. 2. When torqueing it down do it in (2) steps, the 1st @ 1/2 torque spec and 2nd final torque spec.

Just my $0.02...

I have always wondered about the axle alignment thing, gasket, reusable gasket, no gasket at all. Then, there are the people that worry and fall apart about the bearing end of the axle. I'm going just continue to do it the the way they did it.

The reusable gaskets work very well provided U follow their instructions, do not over torque just snug it up.
The 1st ones I used was for the pan gasket on my 727, I would change the filter and fluid every 10K.
I saved alot of times just drop the pan, wipe down the pan and trans surface, gasket and reinstall.
Now they also have reusable gaskets for the Mopar oil pans as well..

Just my $0.02...
