differential

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.

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...

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...

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...

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.

Hello arrma dudes So I’m having this problem on my dual motor felony So I desired to swap the front diff “gp5”to the back and the back “gp6” to the front So when I changed it used it I noticed the front would tighten up but would still roll only if pushed or with it being driven and it would...

hi, why theres no shim on the V5 typhon but there is one on the TLR? the input gear itself is the same ..

Hi all, first post here. Bought a brand new k6 did the usual diff inspection and ran a few packs through it. Shimmed they diff and all still working fine, recently under braking or full throttle from a standstill the front diff is making a loud clicking sound for a second or two then goes...

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...

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...

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...

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...

Hello All, Anyone getting good life from the GP4 open diffs (not LSD ones)?

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!

Hello. Just got a awsome 3s Big Rock home, but i will just check the Diff - what oile should i put in?

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...

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...
