    3s Diff Issues

    I have been having some issues when trying to install the metal diff I just bought for my Granite BLX. It seems like the metal diff is slightly bigger than the plastic diff. The yokes are pinching the diff just enough so the diff can barely move. Not sure what the deal is.

    Does Ear plugged center diff contribute to rear diff fail? (Outcast)

    Current setup on my outcast is max5/800kv with 37/39 gearing, I always run it on punch level 3 and I have already ear plugged my center diff out of the box. Previously on stock setup, there is no issue with it everything runs smooth. Recently I broke both rear CVD pins (m2c driveshaft) and...

    Big Rock Out of the box set up/adjustments to make to the Arrma big rock 4x4 3s

    Just purchased a Arrma big rock 4 x 4 3s and will be running 3s battery with it and I’m wondering what adjustments or set ups need changed or adjusted from factory settings for the best performance. Mainly any shock, differential, or gearing adjustments that need to be made before running it for...

    Vorteks Keep destroying rear diff with a particular set of (heavier) tyres.

    I've got my data imo. Both times I destroyed my rear diff, was with the JetKo MT Extreme Tyre Tomahawk Belted on Arrma Granite Black Rims 14mm Hex (2) tyres. They are quite heavy compared to stock Vorteks, Louise RC MT MCross tyres, so the car can backflip and frontflip crazy, but this keeps...

    Diff Building Help: Notchy Gears

    When re-building the BLX diffs, how "notchy" should the diff feel after a re-build? Notchy, but turning? Completely butter smooth? I'm curious if there is a break-in period that takes out "some" notchiness or if the diff should be completely smooth before installation.

    Kraton 6s Kraton v3 clicking noise from front end

    Hello Arrma forum! I’m working on getting my Kraton going again but can’t figure out this clicking sound in the front drivetrain. At first I figured it was some differential gear that got worn down, but after replacing the worn diff ring gear the sound persisted. I had a new input pinion on...

    Mojave Why are so many swapping to an open diff from LSD on their Mojave EXBs?

    I see many threads and videos about how to swap to an open diff from an LSD, but I haven't caught on as to why. There are some videos I've watched about the difference between open, LSD, and even locked diffs, but many of these lead me to believe LSD would be better for the Mojave. And I'd...

    Typhon Diff Oil Weight in Relationship to Vehicle Weight

    Curious to know—I've read enough to understand the differences between thicker vs. thinner weight f/c/r diff fluid (changing the oil's viscosity if you want to be technical 😂). That being said, I'm curious if the weight of the diff oil should be increased if the overall weight of the vehicle is...

    Granite Screw in the rear differential

    Hey folks, today i made a shocking discovery in my rear diff. The Granite BLX v3 is brand new (only 6 Lipo-packs in). After a quick run on a sand/gras mix surface it started to sound pretty bad. Like a stripped gear or sand in the gears. I stopped driving immediatly to prevent more damage. The...

    Typhon Typhon TLR differential

    I recently got a TLR Typhon. I'm upgrading the middle differential from a 50 tooth to a 46 tooth. When upgrading one diff, do you typically upgrade all of them to the same tooth count?

    Hi All, My first post. I just picked up my Arrma Kraton EXB 8s 1/5. Sos the Diffs still require shimming, if so does anyone have part numbers for suitable shims. (I’m based in the uk) Thanks!

    Talion EXB Diff missing parts?

    Have a "new" (run only twice) EXB Talion. Reading the posts about Arrma quality and diffs without oil, I decided to check and fill the Talion. I notice the front matches the EXB exploded view perfect, no worries. But the rear is missing both of the part circled in red. Is this correct? or is...

    Typhon Typhon diff fluid after upgrades

    So I've had my typhon v4 for a while now and I've beat the hell out of it. Great car. It's snowing now so i figured it was time to go through it for maintenance. The manual says 7k/10k/7k f/r/c for the diff fluid. My question is, I've overpowered the hell out of this thing. I'm running a 1520...

    Hi Everyone, I'm in the process of completely upgrading my Granite 3s BLX's drivetrain. As the post states I recently put in the Hot Racing front and rear metal diffs and upgraded the composite slipper clutch gear to steel. I also added in a 15T pinion. My current situation is that when no...
