Arrma 3S/4S Metal Diffs & CVD Sliders ATF9337 ATF11A01 AR310870 Granite/Senton/Typhon/Kraton/Outcast

Typhon 3S and 4s Outcast Kraton SEE BELOW FOR NOTES
If you've got one of the 3S or 4S trucks from Arrma (Senton, Granite, Typhon, Outcast, Kraton) then you may have had an issue with the plastic diffs or driveshafts on your truck. The new metal differentials from Hot Racing should prevent any ring/pinion problems in the future, as well as offering support for more power. The CVD slider set from Arrma isn't completely metal, but we have stronger parts where the normal plastic driveshafts were breaking. Note, if you have a Typhon, you can make these driveshafts work but you'll need some extra parts (see below). This video is less of a how to, and more of a general overview and some install tips. Kraton/Outcast 4S keep reading below too.
What you'll need:
Metal Hot Racing Diffs (you'll need 2 if you want the front and rear diff done) Part#ATF9337 ebay.to/39aFUL5
Hot Racing Metal Diff cups (you'll need 2 if you want the front and rear done) Part #ATF11A01 ebay.to/2U8FNvh
CVD Slider Set Part #AR310870 (you'll need 2 if you want CVD's in the front and rear) ebay.to/33DqdLa
Hot Racing Metal Diff Yoke Part#ATF11Y02 amzn.to/3badjqG
2.0mm Driver (long, you can remove the stock shafts with this) amzn.to/2WBloAK
NOTES!!! Typhon 3S and 4S Kraton/Outcast
Now, if you have a Typhon, you'll need to change out the wheel hex as well (Typhon 3S uses a different wheel hex mount than the rest of the 3S line). The easiest way to do this is with the Hot Racing 10mm extended hubs for 17mm wheels Part #ATF117XT02 amzn.to/2QC9L8N If you choose the Hot Racing 10mm extenders, you'll need 17mm wheels as well (if you don't already have them-Typhon 3s comes stock with 17mm FYI).
4S Owners!!! The CVD slider set is NOT AVAILABLE for the 4S lineup yet. If you really really need to upgrade your driveshafts, you'll have to swap to the 3S lineup suspension arms (Typhon) and the other related parts (turnbuckles, steering links, hubs, etc). It's probably best to just wait for the 4S cvd sliders to be released. If you have a 4S Outcast or 4s Kraton, you'll only be able to install the diff yoke, metal diff cups, and the metal differential gears.

Here's another two thumbs up for your collection! I appreciate that you didn't edit out the fact that it took some adjusting to get it right. Many people don't get that aspect. Looking forward to more. Be well.

[@sherm7456]

Thank you for your videos. I shredded my rear diff for a second time. Your video makes it easy for me to install an upgrade with out any worries.

[@cristianmarcomonton797]

Just a question please, are necessary both itmes , metal gears and case? or can I run changing only the metar gears?, thanks in advance, sorry my english

[@RCRoads]

Great job on this video. Very informative and easy to follow. Your Kraton really jams. I dread when the time comes where my 3s Typhon or Granite need new Diffs but I can just look back at this video for reference. Awesome Thanks ... 🏆🏆

[@papachilla]

That Kraton body looks good with the Typhon arms and 3S chassis. Thanks for the inspiration. :)

[@jarrodedwards9239]

Very well displayed. You're doing a great job!

[@continuecrushingrc3653]

Thanks!

[@rickbadessa4897]

Man what a great video...been having same issues with stripping and snapping everything

[@Dreson45]

Lol! “Let’s see how it does”.......backflips on take off. Awesome work, I like that rig! 👍

[@Mauq5_Rc]

Thnaks for info, been having problems with my driveshafts breaking a lot!

[@norcalrc]

Try the gpm units if you can’t find the Arrma ones . Don’t get the HR axles. 70$ a pair and they broke every time

[@lyricalcoma1979]

Just found your vids and you are a life saver man, new sub👍

[@norcalrc]

Good knowledge bro, thanks for sharing, I have experienced the same issues you were talking about and handled them in the same manner. I had to subscribe and show some support.

[@nickteele169]

Seriously great video man.i have a granite 3s n converted brushless senton so this is great.i hope theres a follow up video.i just discovered your channel so im glad to find a nee good rc channel.anyways ive actually had great luck with my granite .i know its an ominous reality alway luming with plastic diffs tho lol so this willbe happening.

[@3SonsRC]

Nice video buddy. Would think 4s is PLENTY for this truck especially with your upgraded electronics. Rock on brother and stay safe... New Sub.... Great commentary!

[@BuildingByFaith]

Great video. Can you share how you added the chassis brace? I want to add one to my big rock v3.

[@mexicalikingzzz4983]

Great video bro!

[@SpeedSyko]

I put the 6s system on a 3s senton, have not stripped any gears. But I want to upgrade the gears on these cars. Good to know upgrades are available. Thank you!

[@icyfs3036]

Heyan how did the CvD sliders hold up? Was thinking about getting some but I can't decide which ones to get. Great video and very helpful 👍

[@thenapierfamily]

Thanks for your Video. I have a granite 3s that I keep stripping gears. Your video is the only one that looks like what I need, but I can't find these parts anywhere. You would think that they would make more because of the high demand right now. The factory ones are always on backorder.

[@anotherrcdude1552]

Pretty sweet man!

[@Starkster50]

Thank you for the information. I change the fluid out on rear diff on Granite. 1 million to help lock up rear. Strip ring & pinion, won't do that again and this was with slipper clutch tight half turn backed off, and wheelies on the street. Bat. 7000mah 120c. Three wheelies and boom ! What do you recommend once I replace with metal and I'm running 20t pinion. Thanks And also plastic axles had to be replaced. Thanks.

[@a-1430]

Great video you learn one lesson never run 4s on a plastic spur gear. 👍

[@PopExpo]

I got my arrma metal crown and pinion gears last week. Just gotta use thier composite diff cup that's like 7 bucks a piece.

[@smitheshn6637]

Nice video brother

[@cmarq007]

Shim goes on the cup side. 👌🏼

[@kurt3306]

Great vid :) would you happen to have the Arrma part number as alternative to the hr diff cup? None of the hr diff cups in my country and cost of postage is prohibitive. Was think Arrma part ar310772 but not sure ?

[@Ricardo-qh4ul]

That's bro you help alot I got two of them but i been have more problems with motor than anything and i dont do jumps or nothing like just riding it

[@PopExpo]

When you buy a 3s or 4s arrma truck, you're basically buying a roller. If you like to wrench and put together your own build, which is what I like to do anyways, the 3s/4s line is a good starting point. Just dont expect a quality RTR experience.

[@cristianmarcomonton797]

Just a question please, are necessary both items , metal gears and case? or can I run changing only the metar gears?, thanks in advance, sorry my english

[@1Himiko7Toga]

Same mine are still holding up very strong after 6-8 hard runs and crashes my wheels are stright like a knife i even upgraded my (A-arms for "Rear & Front") all in all i just lube the shafts and bearing so its running good im gonna upgrade my difs very soon. Ill buy the parts some point in time but before i install them ill run and run my car untill its toast inside but just the casual cuz i dont wanna have to put the metal parts in to early but maybe ill upgrade to 6s combo 😂 but its fairly fast so i gotta do more on the dirt to handle my high speed crashes before we go faster up.

[@GuyslacklusterRcReview]

Good info man. Thanks👍

[@continuecrushingrc3653]

Thanks for watching, hope it helps!

[@GuyslacklusterRcReview]

@@continuecrushingrc3653 yep thanks 🙂

[@DOFIXERR]

I need to do this to my Outcast 4S. Tired of poppin’ U-joints and strippin’ diffs (and yes messin’ with the slipper). Also, I thought the spur gears came metal on the 4S?

[@cagerage21]

Badass video man!! Are those 2.8 wheels and tires?

[@michaelrittenhouse2544]

I just received the arrma boost box. Two metal diffs with composite yokes. I bought two alloy yokes to swap onto it. Do you know if I should open the housing and put oil or grease inside the diff? And do I need to upgrade any other gears to make the entire drivetrain metal? I have no real logical reason to go full metal other than. I just want to upgrade the crap out of it and I don’t like the idea of any moving part being plastic. Please if you know anything about the arrma boost diffs or have any tips. Let me know. Thank you!

[@cfmc6201]

My Centre drive shaft melted/snapped a Little Rock got caught in. Disappointed happend after the 2nd run less than 30 minutes on the buggy. Should be alloy. Does any one know of an upgrade?

[@TeamDrif-Tastik]

I have the firma spektrum smart 150a esc and motor on my senton 3s blx. the first two supporting mods were the steel spur and pinion gear upgrades. I got a 17t spur on mine. best upgrade so far for 6s. I use metal drive shafts. as well. next is the metal diffs front and rear . I see from the description that I can use these parts on my 3s blx senton?

[@julianvalenzuela6481]

yes you can

[@VEEZER1]

6s on 1/10 is no fun ;) God damn I love my kraton4s Just stripped the diff after 15 runs brand new. Time to upgrade to HR!

[@riskeyrotors967]

my granite snapped the input gear on the second battery xD only on 3s battery.

[@rockyrc9942]

Just striped my rear diff upgraded my typhon to 4s and she lasted a while but eventually to much torque and power Haha have you had any issues with the new HR differential?

[@horacewashington4690]

Did you use the stock 17mm wheel hex and nut with the Typhon 3s CVD Sliders?

[@cristianmarcomonton797]

Just a question please Does the truck need ATF 11A01 ? If I buy ATF 9337 PArt, or I can place ATF9337 in old diff case, thanks In advance, sorry my english

[@EXTREMERC416]

So far the issue is the diff yoke seperating under 4s power i know the kraton 4s is effected by it but alluminum yokes seems to be the fix. I hope your hot racing diff doesnt eip the seals or somethijg in the future because no way of getting spares

[@troyflanagan4237]

I'm having problems with my plastic gesrs in the rear in of my 4s kratons i want to put steel gears or Aluminum gears that will stand up to my 4s kratons power with a 2400kv Motor and 2 mah 5000mah BATTERYs 1s a 50c 14.8 THE other 1 is a mah5000 100c c 14.8 to much power for plastic gears plus also slipper Clutch comes loose sometimes what should i do put metsl gears in or Aluminum gesrs in my 4s kraton cause motor comes loose and pushes up against the gears i think iam Explaining it right if some out therer can help me with this Question please do

[@kingaj79]

How have the driveshafts held up since?

[@eeezzzzzzz2335]

What shocks are those? The stock shocks on my granite leak bad.

[@jah-jah87]

What modifications is required for the 4s cvd on the typhon 3s?

[@rickbadessa4897]

How have the new driveshafts been holding up

[@mattpotts8561]

My cvds came with metal rings also, where do those go?

[@claytonparsons4963]

welp, i boug the upgraded gear set but didnt know i needed to buy the diff cover as well :(

[@EXTREMERC416]

The only way for the driveshafts to pop out and cant be reused is due to the clutch being too tight i never poped one in my 4s kraton but the rear pin holes are pretty stretched up because it was my first rc and year i locked the clutch all the way XD. Also dont forget to shim the diffs i had to shim mine when i got the hot racing yokes

[@continuecrushingrc3653]

The area where the pins are seems to be what snaps, and setting the slipper can be a pain! Upgraded shafts just means more driving time between rebuilds/breaks (usually haha)

[@troyflanagan4237]

Are Hot Racing diff gears hard to get a hold of?

[@SpeedSyko]

Yikes, I need to upgrade mine!

[@lowridr2]

Sweet are these new i wanted a senton 6s but they dont make them anymore so i thought i would put 6s blx setup in the senton 3s then i found out it has plastic diffs and that was basically a dead end untill now !

[@continuecrushingrc3653]

Yeah these are semi new, came out a while ago in very small quantities. Seems like there are more available now. What’s your goal/use for the car? Like I mention in the video, 6s is pretty ridiculous lol. But at least these should deal with 6s okay...I think.once I have more time beating on the truck I can let you know how it’s holding up.

[@acourtneylawson2065]

That was how I felt buddy..but I’m definitely about to order a 3s box line probably sent on or typhon for sure...the hrvdiffs are huge...I think basically you get 6s power for 3s price cause even the plastic gears can withstand a lot power

[@dogsfam30]

Can you use them on a big rock v3

[@Gazelle0078]

Is there anybody that makes a metal center drive shaft ? I just did this conversion on my Kraton 4s

[@audiS4nissa]

Thanks 😍✌️👌

[@lyftjennings1890]

Are the cvd arms required for typhon?

[@ragsixracing]

Let it be known... You do not need a long 2mm driver to get the stock shafts off of the diff. Just put a little extra pressure on the driveshaft at the joint, and you can get a short driver into the joint area to get it off. Try it...

[@DeathHelper420]

Does this all work for the big rock ?

[@thunderbolt2602]

Hey... I wanna put that center brace on my typhon... do you mind putting those part numbers/ a video about it.. because I have some part numbers on it, but I’m not exactly sure about how to do it

[@continuecrushingrc3653]

Yeah I’ll see what stuff I can get put together for ya

[@thunderbolt2602]

continuecrushingrc I would greatly appreciate it thank you!

[@thunderbolt2602]

continuecrushingrc i also had a question... do you know if this Keaton 4s/ outcast cod composite slider driveshaft would fit the 3s line? I’m assuming so if it is the center drive shaft... the part number is arac3950

[@germanopinheiromartins4547]

how much did you spend on all these improvements?

[@TheTylerjoy04]

Thanks for The Video!! Question, Can I Just Replacement Everything Else Except The Yoke & Driveshafts & Will Fit On To The Plastic Yoke? The Reason I'm Asking B/c My Funds Is Low, Especially When You Have 3 Young Kids To Support & Have Only One Income Coming In..Lol!

[@ThDESTROYER-xd5jv]

Can I lock my diffs

[@BudDingus]

I installed those cvd sliders on my granite that has typhon arms. There is not a lot of contact area inside the sliders with the longer arms. I had a little tumble wumble and the slider popped out of the shaft. It didn’t break, but I’m afraid with continued use it with eat the sliders up.

[@continuecrushingrc3653]

Hmm, I haven't checked how much contact there is in them, I thought it was a bit though. I'm shocked the arms flexed enough for the shaft to pop out. I'll need to pull mine apart and see how much they contact.

[@Roach838]

Help me !!! How do you turn the one end of the new axle to 17 mm ? Please Help Me 🥲😁

[@XAPSRxCasper]

How did these hold up?

[@aznriceboiz5]

do these parts fix the new vorteks 3s blx also?

[@shaquillehemphill3308]

Yes

[@vapeapetn]

so in short, 6S is simply OVERKILL and uncontrollable LoL...Another reason I will stay 4S on my Arrma Typhon. I prefer spending the money on durability upgrades. performance is simply fine on 4S!

[@acourtneylawson2065]

The stock plastic gears are nearly bulletproof from what I heard ...only reason I hadn’t bought the 3s 4s line because I hated the idea of them being plastic...but I’m definitely ordering one now I have been waiting on the metal gears...and they look huge for a 3 or 4s setup...I think they can handle 6s be honest...best bang for buck...a must have for me...how’s yours holding up???

[@continuecrushingrc3653]

Yeah they are pretty tough, I'm shocked. So far, still good. Haven't run it a lot, but I'm not afraid to beat on it much now (well throttle finger wise).

[@troyflanagan4237]

What are sliders

[@winstonoso5821]

Will the driveshaft fit on the big rock?

[@continuecrushingrc3653]

I would think so

[@williemonteiro]

Great content my friend. I’m confused tough. They do make cvd slider for the 4S . Part #ARA310889. You also need the CVD diff outdrive part #ARA31890. Check it out!!

[@continuecrushingrc3653]

I mean, they "have them" but no where has stock. They keep saying, "coming soon" but who knows how long it could be. The 3s lineup took a long time, should have been available last year. Then the beginning of this year, and just now it seems they are more readily available.

[@troyflanagan4237]

Yolks i forgot to mention

[@daerriangibbons1019]

sweet video, I utterly destroyed mine

[@ifitaintbrokefixit3975]

Awesome info i changed mine to 6s and the axles pop off

[@GKCcisco]

First run does all sound normal?

[@GKCcisco]

[@outdoorseveryonceandawhile8236]

I’m destroying the stock ones on 3s

[@troyflanagan4237]

Aluminum Hot Racing gears i want

[@daerriangibbons1019]

try some liquid gravity

[@joshua_luther]

That’s an expensive upgrade.

[@redblue40rc33]

You're better off to buy a buggy that's made for racing or already beefed up like the 6s or 8s buggies...(ex) hyper 7e......built like a tank....plastic just will not hold up

[@michaeljohnson254]

it stripped because u cut a hole in bottom of chassis and its hitting rocks ect....i know alot people do this mod..but its a dumb mod theres reason why they didnt put a hole there lol....

[@continuecrushingrc3653]

The spur gear stripped because of ridiculous power going through a tiny little plastic gear...the slot in the bottom allows the sand and dirt that DOES get into the "sealed" area to fall out. Now that doesn't mean rocks and stuff don't cause it to strip out, but I think this is a screwed if you do, screwed if you don't mod lol. Don't cut a hole and debris builds up in there, cut a hole and stuff can get in there...I think the chances are greater of stuff getting stuck in there and causing damage because it can't get out, but I'm sure tons of people think the opposite! The 6s line has the spur and pinion completely exposed, but they have metal from factory, but rocks do get in there too and crack the spur on occasion! Build, bash, break, repeat haha. Happy bashing!

[@redblue40rc33]

Just buy the typhon 6s......all metal

[@45Rand0m]

Thing broke so easy

[@germanopinheiromartins4547]

Buy a Vorza and be happier

[@DTWC]

All reviews i read say hot racing sucks worse than stock
