Kraton Please send help, going slightly mad (K4s 2.5 center drive shaft)

[Barmaleus]

Hi all!

So my lovely K4s 2.5 will seemingly need a new center drive shaft soon, as rocks are eating it away.
I am looking at options on AliExpress/Amazon - stuff made from aluminum. Feels like it might be sturdier? Hopefully.

Thing is, 99% of sellers are not giving dimensions of the product, just Arrma product codes. Also, 99% of the center drive shafts I see are for 3s/4s Granite, Senton, Typhon, Vorteks and any other model, except Kraton 4s 2.5.

From what I measured, the distance between the front diff and center diff on K4s 2.5 is around 24cm. The stock center drive shaft is roughly 25cm when not compressed. In this state, there is around 3.5cm of the longer shaft in the short one.

Soo... I am trying to understand if any of those Granite, Senton, Typhon, Vorteks drive shafts would fit K4s 2.5? Arrma does not state any dimensions on their web either.

Could someone point me in the right direction? Or just send mental help. Thank you in any case =)

PS. I am based in Europe.

For example
This looks like it MIGHT fit. But no dimensions, ehh https://www.aliexpress.com/item/1005005701494542.html

In other news, this one is 278g long. Which is... interesting.

I got a aluminum one for my moijave 4s and with sand and stuff getting in it and the aluminum itself deforming slighty because its made with cheap stuff it made it very annoying to remove when I needed to. Going to keep using it but I will replace it with a plastic one when the time comes. Regarding your question granite/senton/typhon will not be long enough sadly, the new 2.5 chassis is quite a bit longer than them

@StephenSchandelmayer I see, thank you. The longevity of aluminum concerns me too. Perhaps it is easier to have a pair of factory ones and not worry about dimensions and stuff. And just change whenever one breaks.

I have a K4sv2 and I up graded to the new center diff. I used my stock drive shaft. All if not most 3s cars do not run the XL chassis. I think that the stock one would be best. It's cheep and it works.

I ran into the same issue with my v2.5 4s outcast. Oktays bumper makes a good one that is correct, can't speak for anyone else

 

[Barmaleus]

@Johnboy5586 Right. I saw Oktays, it's around 30 something euro + 17 euro for shipping. Exploring alternatives. Perhaps I'll just get a factory one as a spare.

Yea there's a site here in the states that has them in stock but they're like $56, I just left the stock one in it

Maybe you should try something like this.

Not the best example but there is some good looking ones for the 6s which have fine holes in.

This one being waterproof, I’d be worried about overheating.

 

[Barmaleus]

@danny1202 I actually have and use one of these from Dusty Motors. It helps keeping dirt away.
On the other hand, if a rock gets inside, it will most probably have hard time getting out of the chassis. The seal is not ideal, so rocks do get inside.

 

[danny1202]

Mmm maybe you should try and custom make a prop shaft cover

 

[Barmaleus]

@danny1202 This is where my thoughts are now, yes =)

 

[danny1202]

There is options to do it. Make two and I’ll buy one off you

 

[Barmaleus]

@danny1202 Nah, man, I'd just share the print files so anyone could do it. We'll see how it goes!

 

[danny1202]

Haha I was thinking of a piece of wood glued to the heat sink

 

[neighborhater383ci]

here is a link to the one I have on eBay. Super stout but still light and works with the center diff

 

[Barmaleus]

@neighborhater383ci Thank you! Tho can't see the link sadly. Is it the Oktay's one? Specifically the XLWB chassis?

Nope off brand eBay

 

[Barmaleus]

@neighborhater383ci Hmm, this does not look like a XLWB chassis tho. Might be too short.
One of the comment on eBay says "Item did not fit my Kraton V2 so seller let me send it back.". So it looks like it's too short for XLWB, sadly.

Becarefull using these dust covers.i bought one and it caused everything to over heat.i took it off and my temps were back to normal. From what I noticed it doesn't allow for free air flow .or enough.so just some food for thought

I have the xlwb and it fits just fine

The pic I posted of just the shaft i just realized was an outcast shaft. I have both shafts lol
