FLM Rustler Diff is red now?
 

So I ordered the Rustler FLM diff through Mike. The diff case is anodized red, instead of the plain aluminum. It was suprising light and easy to assemble. I just added 10k diff oil in there for now, to see if it will leak.
It did come with two thin washers. I didn't know where to use them, so I put in the inside, to butt up against the small O-rings on the output shaft.

Please do let us know if it is oil-tight. I got tired of my Slash's diff leaking so I JB-Welded it, but it understandably drives differently.

I had it sitting for a day before installing it. Didn't see any wet spots before installing it. I didn't like the JB welded diff with those big 5.5" crawler tires. I used 10K diff fluid in the stock case and it didn't last too long. So I'm giving the FLM case a try. I'll post again when I open it after few good bash sessions with my son.

Reporting that my Rustler still has diff action going on. I haven't opened it ever since I installed diff. Good stuff!

Here's a vid of the Rustler in action. Using the HPI dog bone conversion and crawler tires. Pulling my son up on a driveway. 3S Lipo, geared 58/25 mod.8, with Tekin 1900 buggy motor. I wasn't able to do this with the stock diff, as I would end up with a one wheel burn out.
