Does The Mojave 4s Center Diff Fit 3s & 4s Arrma RCs? | Watch FIRST!

Will the new center differential fit the Arrma Granite Typhon Outcast Kraton Senton Limitless Infraction Big Rock to replace the slipper clutch? Join me to find out!

[@IsaacSchultz-lz8jc]

I do appreciate it, that you actually take apart most of the things in your videos just to show the quality, I really appreciate it.

[@DoRC]

Glad you like it. I enjoy doing it!

[@django2467]

Sir you are a God send you helped the entirety of the arrma 3s platform guys worldwide who needed that question answered don't stop doing you 💯👊🏽

[@DoRC]

Glad you enjoyed. Like I said it is possible that you could jam that thing in there without the modification and maybe other chassis are different though They all look the same to me but I'd be concerned about ever getting it back out again.

[@GeddyRC]

I predicted they would release basically this exact thing (albeit not from a new car, just as an optional upgrade for the pre-Mojave 4S lineup) so I'm pretty stoked to see it fits. I've got a Kraton 4S that I'm definitely dropping this thing into.

[@DoRC]

Yeah it's possible They will release a several one that doesn't require any modifications but as it stands right now unless I really missed something which I don't think I did I don't think that this module will ever be officially compatible since the chassis needs a little bit of modification to fit well.

[@wvlfkvnt]

Finally ordered all the pieces to completely build the center diff, and I just now obtained the power module housing. This is gonna go on my Typhon that’s running on 4s castle system now. Thank you for this. M2C has motor plates now!

[@DoRC]

Nice! Let me know how it goes.

[@wvlfkvnt]

@@DoRCJenny’s RC had made everything I’ve done so far possible. I just got confirmation my housing order was successful. So here we go. I’ll try and make a video.

My Outcast 4s is definitely getting this upgrade

[@DoRC]

Yeah I think the 4s vehicles definitely need it

[@K5_RC]

Oh man even if they do fit in current models, we gotta see V3 Kraton and Outcast 4S rigs with center diff and updated chassis formula! The Mojave chassis is tough as nails!

[@DoRC]

Yeah Yeah it would be nice to see an updated chassis for those that has the slots and holes already cut for this.

[@K5_RC]

@@DoRC absolutely. This could change their BOOST/MEGA/3S/4S line for good!!

[@DoRC]

@Krapper515 Yeah I predict a lot of people will be doing this upgrade. I think these parts are going to be out of stock for a long time.

[@ellc.6143]

I have one on the way for my granite. I was never a fan of the slipper clutch. Its a pain in the rear literally. Now its gonna have a center diff way better alot more reliable. Granite is gonna be a tank when im done with it. Thanks for the vids.

[@DoRC]

Yes. The only advantage a slipper clutch has is cost for the manufacturer. Pretty much everything else goes to the center differential.

[@lautrique]

Thanks for confirming that the center dif module can fit in the other 3/4 s chasis with some minor modification.

[@DoRC]

Yeah it's possible it'll fit different chassis differently but I looked and they all basically look the same in that area. It's also possible you could jam the module in there without doing the modification but you may never get it back out again.

[@vogalan2067]

Yes thank you! Been waiting for a video like this since the mojave was announced. Definetly going into my outcast! Best wishes from austria

[@DoRC]

Awesome let me know how it goes! Thanks for watching :-)

[@make4all2000]

the option to adjust the distance from the pinion through those holes is that without the rear cover the differential does not sit straight and you can adjust the distance incorrectly, so if you put the cover on it is something else and tighten the screws from the engine through those holes and check the distance from the pinion audibly

[@DoRC]

Yeah you can but it's still going to be a bit of a challenge without actually being able to see the gears at all. It's a nice option though.

[@VDVC-RC]

Thanks for pioneering this center diff adaptation hands on! Was planning on doing this with my Kraton 4sV2, but unfortunately "Horizon's new System" cancelled my Mojave 4s order...😢 I may just order the center diff module for my K4sV2 install it after needed modification, then continue with my 6s Mojave chassis build... I have a lot of goodies on the way.

[@DoRC]

That sucks. Yes they also canceled mine but I was able to get it reordered. I'm not sure what's going on with them but hopefully they get figured out eventually.

[@jasonpantages7248]

Definitely going to put one in my 3s Typhon. I fabricated my own slipper eliminator and ran it till the out drive split into 3 pieces. Was looking a replacement slipper or eliminator then ran across this. So yes I will be getting one ASAP!!!

[@DoRC]

Center differential is the way to go!

Bad ass vid dude. I actually swapped my big rock chassis with the Mojave one and everything lines up perfect, I’ll have a vid up on my channel here soon. Side note: the Mojave bumpers also work on the other line. It’s pretty sweet

[@DoRC]

Nice! Yeah pretty much everything is cross-compatible on the different models. Can make for some pretty interesting hybrids :-) Thanks for watching!

[@ragsixracing]

Now I can pull out my mt converted 3s Typhon, and start running it again. I hate no center diff in a 4wd off road vehicle. I've been wanting this mod for 2 years...

[@DoRC]

Yeah the chassis mod really is not that difficult And maybe it'll fit without the mod on some chassis. I don't think so though as they all kind of look the same from what I'm seeing. You might be able to jam it in there without doing the mod but I'm not sure you'll ever get it back out again

[@jasonpantages7248]

Have you installed? Was it difficult to modify and how do you like the outcome?

[@Adubbs87]

I was wondering about this since the Mojave came out! Thx for showing us how easy it can be… bye bye to all the center diffs on Jenny’s lol

[@DoRC]

Yeah it's pretty straightforward process. There are a couple of people that have installed it without modifying the chassis but I don't think I would recommend it. If you can manage to cram it in there it's going to be a pretty fun task getting it back out once the dovetails get loaded up with dirt like they do.

[@Adubbs87]

I remember cramming a 4074 in my granite back in the day. I had to remove receiver box to get it out because of the dirt in the dovetails.I think the way you did it is the way to go

[@RCPropaganda]

Very interesting. It might a great upgrade for my 4s outcast.

[@DoRC]

Yeah I think this is going to be a required upgrade for the 4S trucks

[@RCPropaganda]

so I will have to trim my chassis down a bit to fit it?@@DoRC

[@DoRC]

@@RCPropaganda based on my experience I believe that is best. I was physically unable to get the module to fit into the chassis I tested on and they all appear to be the same in that area. Other people have managed to jam the module in there but I don't think it's a good idea and I think they're going to have a really hard time getting it back out even if it is aligned correctly once installed.

[@GamezOfWar]

It fits in the Kraton 4S perfect, no trimming needed

[@DoRC]

@GamezOfWar have you tried to remove it after the dovetails get packed in with dirt?

@@DoRC sweet! Thanks!!

[@DoRC]

You're welcome!

[@chriscrisafulli798]

When you were doing the swap, do you know if the factory motor mount plate fit in the center diff module? I have a hot racing heavy duty motor mount with the chassis brace that I’d like to use. I’m guessing the chassis brace will be too long.

[@DoRC]

@@chriscrisafulli798 I didn't specifically look but I don't think it will. The bearing on the center differential is quite a bit larger than on the slipper clutch so the hole for that is going to be too small on the slipper clutch motor mount plate unfortunately.

[@franklee6301]

Seems the center diff is currently available via Horizon but the mount plate is on pre order and i couldnt find the modual at all.

[@DoRC]

That's unfortunate. Yeah I know a couple people had them in their hands but I'm not sure how they got a hold of them. Looks like it's either going to be buying or Mojave or wait for Jenny's for now.

[@Macgyver46]

Wonder how this will work on the 4S outcast v2. Currently trying to build one and don't have these parts yet so this could be an interesting upgrade to consider.

[@DoRC]

I don't see why it wouldn't. The Outcast V2 chassis appears identical in that area too What you saw in the video so with the same trimming it should fit just fine.

[@Macgyver46]

@DoRC I mean change the handling etc. I city bash and wish this came out when I still had the vorteks! That slipper got replaced 5 times before I sold it.

[@Macgyver46]

@DoRC I think the 3s and 4s chassis from arrma are basically the same just SWB MWB LWB and i think an XLWB. Yeah I spent way to long shopping for the MWB. Not sure if it's backorder.

[@DoRC]

@@Macgyver46 oh well it really depend on what viscosity fluid you put in it. If you go fairly thin it'll make a huge difference. Stick a couple ear plugs in there and it'll behave very similarly to the slipper clutch just with the ability to help save the drivetrain from shock loads.

[@DoRC]

@Macgyver46 according to my recollection and the pictures I checked they all appear to be identical in that area. That means that you'll probably have the same problem as I did no matter which chassis you're installing it on. Not a hard problem to fix though.

[@colinmorand129]

Cool vid, on the flip side yeas it will make the drive train less vulnerable in terms of stress,, BUT it will sacrifice some Of the snappyness and bitethat you had before = FUN

[@DoRC]

It can do that but if you're worried about that problem you can just put silicone ear plugs in it and it'll mostly lock it up giving you pretty much that same snappiness without sacrificing the drivetrain protection too much.

[@cjchannel12RC]

Cool video, You've made me want to do this to my new Vendetta and you used the Infraction as a test which is based off the same platform as my Vendetta. Maybe someday i'll do the Center Diff mod to it plus a 4s system and the metal 4s front ear diffs. One last thing which new 4s chassis would fit the 3s Infraction\Vendetta.

[@DoRC]

I think the chassis are different lengths so I don't think either one of them would.

[@cjchannel12RC]

@@DoRC Oh okay, Although i haven't driven mine yet so i don't how it will hold up but i can definitely look into a center diff swap someday if the stock slipper fails. It will just require some mods to make it work.

[@dandyer8351]

Be nice if you could do a weight comparison between the two setups.😁

Yeah but did you notice how he didn't actually show it being installed? I'm sure you can jam it in there if you push hard enough but good luck getting it back out again especially once some grit gets in and does its thing like it usually does in the dovetails. He even said in the video it was super tight. That's not what you want. I would recommend making the clearance so that it installs easily. If you don't you're probably going to be pretty unhappy when it comes to time to take it out later.

All you need is the center differential itself the power module and the motor mount plate. You can look at the exploded view for the fee 2.5 outcast 4S and get the part numbers from there.

[@make4all2000]

Hello! do you really think there is 10 million cst oil in this diff? or did I not understand well? I've finished putting the power module on an Outcast 4s v2 and it seems to me that it inflates the hubs too much on the front, it actually works better but I think it needs a little thicker oil, but on the other hand I'm a little afraid not to force the planetary gears or the central axis...thanks once again

[@DoRC]

I'm not entirely sure what weight fluid is in there. It might be thinner than that. I wouldn't worry about over stressing the internal gears. I have put pretty thick stuff in quite a few differentials and I've never had a negative outcome because of it. I'd recommend putting a little bit of silicone ear plug in there and see how that works. It'll nearly lock up the center differential but will still give you enough give to protect the drivetrain.

[@DoRC]

I don't have one currently but at least in the pictures I've seen of the chassis the V2 Outcast and Kraton appear to look identical to the 3S models. It may be possible to install the differential without modification even on the 3S models as I've seen a couple other people do it but I think creating that extra room will make life a lot easier especially when it comes to taking it back out again.

Will the 4s axles work on the 3s vehicles? I have a senton we swapped to 4s and it destroys the stock shafts.

Can u use the oem 3s motor with the center diff instead of swapping them out

You can use the 3S motor but you have to use the motor mount and module from the 4S as the center diff won't fit in the 3S mount or module.

Great video mate I've been asking this question since this centre differential came out. Now would it fit vorteks 4x4 3s and what would the part numbers be for any part change ?. Ps running 4s plus on vorteks 😊

[@DoRC]

Based on what I was seeing when I looked at various chassis online I believe they're all identical in that area between the 3S and 4S cars up till the Mojave so it should fit the same way as it did in the video. If you look up the exploded view for the Mojave 4s You can find the part numbers on there. Thanks for watching!

[@scaleworksRC]

I got a Granite 550 on sale for $150. It costs about $115 to upgrade to a center diff if you already have the motor end ESC, but it's worth the trouble over going for the convenience of the $200 boost box imo. It's a nice combo, but still has the slipper setup👎

[@DoRC]

I've heard you can get the center differential module on AliExpress for a lot cheaper.

[@DoRC]

@PigglyWigglyDeluxe Yes without the differential it'll fit fine because you can put it in an angle. With the differential in there it becomes a lot more difficult because the splines on the differential have to line up with this lines on the rear diff input shaft. That's what was binding on me.

@BradWorona Nice yeah when vehicles first come out googling new parts can be very hit or miss because until those parts start getting available on third-party sites I think Google has a hard time automatically crawling that information and making it available.

@@DoRCI know running that on 4S is going to lower my rpm, how far should I gear up to compensate for the lost rpms? Im going from 3S with the stock 3200kv so a rough 35,500 rpm down to a 4S with a 2050kv which will be around 30,300 rpm? Or should I just toss in 4S diffs and cvd’s and run it balls out at 6S?

[@DoRC]

@thatmadscientistfromny5362 yeah that math seems about right. I would maybe go two teeth on the pinion and see how that goes.

@@DoRCwill 4s front and rear diffs fit my vorteks? Im sure Im gonna grenade the stock 3s diffs in short order and after I get my big bore shocks and cvd’s I want to run my vorteks on 6S and see if it will hold it

[@DoRC]

@@thatmadscientistfromny5362 yes they will.

[@Batchat2352]

So its no longer a friction fit. It easily slides out now after removing the screws. They will iodate the current 4s and 3s to make it compatible. Im sure before xmas

[@DoRC]

No the fit is pretty much the same as with the 3S ones. When they're brand new they all come out pretty easily. It becomes more difficult as soon as any grit gets in the dovetails. None of them are designed to be a friction fit from the factory though. They're supposed to be held in by the little block that sits in front of them and the latch at the top. It will be interesting to see if they update the other chassis to be compatible.

[@jonhowland4985]

As a noob….what’s the benefit of doing this?

[@DoRC]

There are two main advantages to a center differential. The first one is the allows you to adjust the fluid in that center differential to tune how the truck behaves. If you run thinner central differential fluid under heavy acceleration the truck will be less likely to wheelie because power will be allowed to bleed off to the front tires. The second and more important benefit is that it allows energy to dissipate through the drivetrain. For example without If you land a jump on just the back wheels when those wheels start to spin up or slow down the entire drivetrain has to take all of that inertia because it's all locked together. A centric differential decouples the front from the rear so that those loads can be dissipated so it really helps save the drivetrain.

@@DoRC Thanks for the detailed explanation. 👍🏻

You're welcome and thanks for watching!

[@RC-Kwagga]

Great video, have been thinking about this since they released the 4s Mojave. Question though, can’t you just replace the 3s slipper clutch with the center diff and keep the 3s power module? Does the center diff fit on its own? Then you wouldn’t have to mod the chassis. Would love to know

[@DoRC]

Unfortunately no. The center differential is quite a bit thicker than the slipper clutch and uses different size bearings. It's got to be the whole module.

[@666cemetaryslut]

You honestly expected it to fit in there??

[@RC-Kwagga]

@@666cemetaryslut that’s what she said

[@ruuster83]

only my big rock is getting a diff. the vendettas get spools and the granite will be fine w a slipper

[@DoRC]

That sounds pretty reasonable. Unless you're having a problem with the slipper the smaller vehicles probably don't need it

[@ruuster83]

@@DoRC thanks for this quick video,, we've been dying to know if it will fit

[@DoRC]

@@ruuster83 Yeah I've been itching to find out too. I was so curious about this I ended up putting this video out before my first video on the Mojave. That'll be coming out tomorrow so stay tuned!

[@TheMitsosBlog]

Anyone wanna try on a Typhoon 3s?😁

[@DoRC]

Based on the way the chassis looks I don't think the process would be any different. All the vehicles other than the Mojave appear to be identical in that area.

[@Hungrybird474]

Anyone done this to a granite yet ?

[@DoRC]

I think I've seen a couple of videos on KZbin where people did. The basic chassis design is identical between all of the 3S vehicles so it shouldn't be any different than this.

[@boduke9428]

Why not just use the Mojave chassis also? The 4s Outcast and Kraton chassis are dirt cheap. Won't the Mojave be the same as the Kraton and only a little longer than an Outcast?

[@DoRC]

Not sure about the length. I'd have to measure them. Hopefully they'll come out with updated chassis for the other two that already have the updated area for the spur gear

[@PigglyWigglyDeluxe]

THE CASE DOES NOT COME WITH THE RED ALUMINUM PLATE. Ask me how I know. 🤬

[@DoRC]

That sucks. I'd heard someone else say it did but that's why I said I wasn't sure.

[@PigglyWigglyDeluxe]

@@DoRC my shop ordered a few of the cases and diffs. We didn’t order plates because the picture of the part number CLEARLY showed a motor plate. Once they arrived, no motor plate.

That's 2 videos in a row you copied, Earl Morehead and Jay Tee. Come up with your own videos, c'mon man

[@DoRC]

Okay so first of all Earl Moorhead did not provide a solution to the problem he just complained. My video provides a solution and then tests the solution so I don't really think that's a copy. Second check the time stamps on the differential videos from JayTee and me. Mine came out first :-)

[@JonathanPARADIS-nb5bw]

There's only so much going on in the RC world at any given time, there's going to be some overlap. Everyone and their mother with a 4S or 3S Arrma wanted to know if these will fit.
