Surprisingly, Arrma actually used some thread locker on the stock screws!I would not be concerned. Make sure you do not get fluid in the 4 screw holes. Use threadlock on metal to metal screws. Fill it to just over the crossbar. Looks like this one was filled pretty well from the factory.....not always the case. Good luck
I grabbed some 300k; curious if it strikes a good middle ground with stock F/R weights.Looks good, at least it's up to the proper level compared to most factory setups. I would decide what weight diff fluid you would like to run, take the diffs apart, clean them and refill them.
In my Talion 6s, Typhon 6s v5 and Kraton 6s I run 20k/500k/60K.. F/C/R. You want a thicker diff oil in the center so you get better power distribution front to rear. You want a little lighter in the center for better steering under throttle.
Had to let this sucker drain over night and still had some residual fluid in there! Gently warmed up the case to see if it'll help.Just put it upside down and let it drain for 15 or 20 minutes. Then you can inspect, shim, and then fill. Color is pretty normal in my experience. Here’s a great video.
You do heavier in the rear?20k/500k/60K.. F/C/R
I really like 60/500/30 I’ve never tried heavier rear vs lighter front.You do heavier in the rear?
Have you run it yet or is this out of the box?Opened my center diff for the first time and wasn't sure if I should be concerned over the color/look of the stock fluid. It appears metallic, but doesn't feel gritty. Anything I should look over before tossing in new fluid?

SameI really like 60/500/30 I’ve never tried heavier rear vs lighter front.
Here’s the first time opening one of my OC EXB diffs after 8 packs.I've run about 5 or 6 packs through it.
I could have that backwards lol.You do heavier in the rear?
Use blue lint free shop towels and wipe out the old fluids. You don't have to wait for it to drain.Surprisingly, Arrma actually used some thread locker on the stock screws!

Appreciate the feedback all, glad nothing is out of the ordinary
+1I really like 60/500/30 I’ve never tried heavier rear vs lighter front.
I’ve been out 3 times since I finished my FT I’m running 60/500/30 and it’s perfect for the weight of the vehicle. I can wheelie if I want to but it’s controllable. I’m going to try the Magen shims.+1
I find those oils above, are just about perfect for most of my 6s Off road rigs. Sometimes 300k center is also an option. The Fireteam come with 200k at center FWIW. While all the other OPEN diffs came with 100k at center. Except the Typhon TLRT. (is even thinner) Normal for the oil to darken as the Sat and Sun gears break-in/wear. When it turns to a sludge, its time to change it out, about every 15-20 runs, if nothing else fails before.
Best to not use the Arrma gear shims/washers.
Use Mugen Seiki # E0206. Enough shims/washers for all 3 Arrma "Open" diffs. Diffs will last way longer.
I’ve been building kraton diffs for 12 years. I rotate diffs on a schedule. I keep spares ready to roll.Impressive FT there. Very neat. The best upgrades.
Your rig there absolutely needs those Mugen Seiki diff shims. Otherwise you will become a slave to those "Open" diffs. All 6s rigs are this way.

Looks great man! Those tires look much better. I never liked how the stock ones looked.I’ve been out 3 times since I finished my FT I’m running 60/500/30 and it’s perfect for the weight of the vehicle. I can wheelie if I want to but it’s controllable. I’m going to try the Magen shims.
