this set up is used in the new X SS 4.6 diffs - i am not even sure if alloy diff cups like these are even available in the market

does anyone possibly know what these parts(1-4) are and where they go. part numbers would be a big help - if this set up is new and will be released only when the X SS4.6 will come out then plz ignore this post

thanx

I think you may have to wait for the 4.6 X to arrive first...
However there are aluminum diff cups at hand by many manufacture's...
search ebay for them

ViperX

ofcourse they are - thanx for the info

i already have the nova alloy diff cups installed in one of my x - i was just curious about them 4 bits that i have squared out and if available, wanted to try them out in my other X

p.s. if i m not mistaken, arent u the one who bid his farewell to this forum - u still here?

The 4 square pieces go on the end of the spider gear shafts against the diff cups. I would think they will only work with the X SS cups.

ViperX

pretty sure ur right

this pic does what i believe show them between the spider gear shaft and the diff cups - i m liking what hpi has done with the diff cups [sm=spinnyeyes.gif] - cant wait to test em out

#1-- Shims for the spider gears
#2-- Shims for the side gears
#3-- Looks like they might be shims for the bearings...
#4-- Steel seats for the cross pins


Steel seats(guides) inside of a plastic cup would have been an upgrade, but to put them inside of aluminum cups is a serious effort on their part to increase longevity. The diffs are the main thing holding these trucks back and I'm excited over these changes.

Im getting a set thats for sure. I really dont think there will be any need for easy access to these bad boys.

that is the same setup in the genesis and nemesis and probably in the 7.7.

ViperX

got it back with a complete front and rear diff replaced with new ones - i was told they were the root of the problem - not much detail provided

strange thing is that i dropped a working diff out of my other X and the problem persisted

i dont want to stress my lhs anymore so i ve given it a rest - the truck runs fine - havent taken it out much - to be honest, i dont even want to talk about it - it pisses me off

anyway - i appreciate ur concern

ViperX

yes it does look very similiar to the cen genesis diff - i thought hpi came out with an original design - if cen uses it, i presume its a heavy duty setup to suppost that .46 engine - does anyone know of any genesis diff issues?

Similar, but I think it was Kyosho who first started doing that type thing.

Why can't they just make a reasonably-priced diff-set up that you can just whack in there and forget about?? Maybe that's a dumb question.. But is this going to be a new option - or do you ALWAYS have to assemble, shim, etc.. yourself??

They DO have this kind of set-up here in Germany.. It's called the Nitro Diff-mod from some shop.. Everybody says they're great - and they better be - they cost €120 - per diff!!... I think they use Kyosho housings.. - as well as those little square-looking bits that slide down between the housing and the diff-pin(or whatever it is... I'm WAY clueless here..)

If I start having trouble with my new SS, I may just go that route - unless this HPI unit will be sold as an upgrade - AND doesn't cost a ton.. Anybody have even a guess what these new X SS diffs will cost??

R.s.D

for people that cant visualize it
i scanned the exploded view from the manual

well the pic is pretty big so click here

1 goes behind the spider gears
2 goes behind the large bevel gears
3 is used to shim the entire diff side to side to adjust pinion/ring gear mesh
4 has already been cleared up

BTW-these gears appear to be identical to the Hot Bodies hardened diff gears
