differential

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...

Hello, I need to replace both front and rear diff cases on my K6 EXb. I want to get the HR ones. I am not certain if I need two of the same or if there are separate front a rear. Also if anyone has a lead on tough replacement cap heads for keeping the shock tower on, I would be thankful.

I'm doing bashing (not speed runs) and I was thinking to change the diff fluids to 60/500/30 K cps (f/c/r). Stock are 10/100/10 K cps. Next week I'll pass byt the LHS to get them. What are you guys using?

Hi, I have a question: The weight off differential fluids, do they work the same on LSD as non-LSD differentials? Couldn't find out myself (fast enough), so i hope someone here is kind enough to help me in my quest. What do you ride/recommend for a Kraton EXB 6s and why? 🚀 Kind regards from...

Hi all, I figured I'd ask this question now for when I inevitably break my current diffs. What is a durable input and crown gear for bashing in a Typhon. I currently run a castle 1717-1260kv with a 30t pinion and a 46t spur on the stock diffs. Thanks in advance for the help.

Hey everyone, I'm starting to be worried about how often my stock front diff on my Granite strips a tooth or two. I've rebuilt it too weeks ago, ran about 3 packs through it and the input gear has a tooth slightly shorter than the rest, causing it to slip once in a while. Now the infuriating...

I personally is just a basher, so should i just go with the thickest oil i can find?

Got a new diff and input gear. Put it all back together but when i put the diff yoke on and spin the diff it feels like its binding. If i take the yoke screws out it spins super easily and smooth. As soon as the yoke screws are snugged up or if i pinch the yoke closed with my fingers it binds...

Me and 2 other buddies who all have granite v3's got new batteries yesterday. We each bought the Ace gens 3s 8000mah 100c. Today the first time trying them 2 of us blew our rear diffs and 2 of us blew a tire. Is it possible that the battery is too powerful or is this just a coincidence? Also the...
