Installing HD Spiral Cut DIFF GEARS In My Traxxas XMaxx

[@scottlesage386]

The helical gears will give you more contact patch between the gears than a straight cut gear. It’s not a lot but it does make a difference. And the chrome/moly is quite a bit better metal.

[@RCKnockout]

Yep…..these unfortunately stripped on me though lol

[@scottlesage386]

Ya, saw that, didn’t take very long either. Guess you’ll have to switch up to the 8s gears.

[@RCKnockout]

@@scottlesage386 yeah that’s what I run now

Nice nolan, input 1M with a mix of 50k diff fluid on front and rear diff and on my center diff i put 20M diff fluid on my xmaxx

[@RCKnockout]

Thanks man! How’s that work for you?

[@oscarmike131]

@@RCKnockout its good feel a lot smoother granting im running 1100kv motor and the xlx2. It hold the the drivetrain with that much power

[@RCKnockout]

@@oscarmike131 good to know thanks!

[@rclife3231]

My xmaxx sounded like that and it was one of the spider gear bars in the center diff that broke

[@RCKnockout]

My center diff so far hasn’t had any issues…..it usually seems to be differential gear or spur gear

[@DeRock401]

If you run big power (like aftermarket motor and esc) a metal diff cover for the front and rear will really save your diffs!! Wouldn’t hurt to do it for stock motor too it’s good protection.

[@RCKnockout]

I do have the alloy diff covers on one of my Xmaxxs….have you had any issues? I’ve always been kinda worried that the metal cover will make the bulkheads more prone to breaking

[@DeRock401]

@RC Knockout no. I am running mod 1.5 gears so the metal cover is really necessary! It’s only been a few weeks so I can’t really say for sure how it strains the bulkhead or not.

[@RCKnockout]

@@DeRock401 I gotcha…..well let me know if you have any issues

[@RetiredTechnician]

Spiral cut gears aren’t necessarily stronger, spiral gears are little quieter when they mesh.. great for road cars, that’s why race transmissions sound so much louder and whine as they’re straight cut, I think the hardened steel will help a lot too.. 10:46 is probably the main cause of the pinion/crown failure.. it’ll flex the plastic under load, Great vid btw the xmaxx looks awesome for tearing up 👌

[@RCKnockout]

Thanks for the info. These gears already got chewed up though lol 😂

[@RetiredTechnician]

@@RCKnockout ohh 😮 that 8s power 😂

[@mikegent2676]

Nice mechanic gloves what brand are they?

[@RCKnockout]

No clue

[@Mr316jon316]

What gears do you run? I’m going to probably buy vitavon… but I’m not sure if they are worth it. I noticed you said these already broke? Any good recommendations?

[@RCKnockout]

The stock 8s gears is what I’m using now

[@digeolrc8586]

Which one better spiral cut or straight cut diff and bevel gears?

[@RCKnockout]

Usually spiral cut are stronger….but these ones still ended up stripping on me….I’ve gone back to the stock diff gears at this point

[@digeolrc8586]

@@RCKnockout how if spiral +bevel siff using to MT rc, good torque is it?

[@RCKnockout]

@@digeolrc8586 not sure what you mean?

[@dstjamesrc6395]

Did that fix the clicking noise? Mine is having the same sounds.

[@RCKnockout]

No….these diffs actually destroyed themselves after one or two bashes…..wouldn’t recommend them

[@achraff9748]

Nice 👍

[@never-stock-rc2968]

They sell these for the e Revo 2.0??

[@RCKnockout]

Not sure?

[@TheMatt70140]

What gears are you running now?

[@RCKnockout]

I’ve got the stock 8s hd ones in it now
