1st 4 you listed are all the same, 13/43 ratio. Not sure about the mayhem.

Thanks
So the only diference is the case. ( plastic vs silver alu vs blue alu)

So Ok for the 4 corners.
BUT for the center??
I use
http://i265.photobucket.com/albums/i...c/trac9151.jpg
Can I bore ( drill) them out to 8mm.
Or do I need something else like 2 of
http://i265.photobucket.com/albums/i...mmcouplerw.jpg
If so, how do i connect them to the CVD.
Thanks.

Yes, i know but my Q is for the center shaft.
The one that goes from 8mm diff pinion output to trans.

Yes, you can drill out the stock part to 8mm to fit the diff shaft- seen it done a couple times. You cant use Mikes part with cvds, you'd have to use dogbones with different drive cups that he sells (8mm bore), or possible drill out the cvd to 8mm, but that might weaken it too much.

Thanks Neil, that's what I was thinking.
I'll go with Traxxas CVD drilled to 8mm.çà
We'll see if it hold up.

Just when I got this thing all tricked out, added mechanical brakes/ redid the suspension/ the dam MMM go's poope :( when I flip the switch only one of then turn on.... guess i need to send them back to castle.. they were V-1's

pics will come soon.

Mechanical brakes! Nice. Definitely get v3's and post pics, you build some really nice rides, I like all your youtube stuff.

I'm posing this question to the 2 people who posted pics of their projects. I was wondering what you used for the center diff. The mount, diff, top plate, and is that a t-maxx motor mount on the center diff? I am new to the forum and just getting back into rc and saw that this thread is based on an idea I had been thinking about before finding this forum. Thanks for any answers and sorry for length on message. :smile:

With the agreement of “IT’S Me“ I post my step by step process to make this mod.

1: It will be cheaper if you have already:
- Center dog bone.
- 4 old and unused drive shafts. (replace 1/8 diff output shaft )

2: It cost me (include shipping cost to Canada):

- 2 x LST 2 diff = $43 us ( 43/13)
- 4 x 1/8 diff output shaft + 2 x Drive cup - 8mm bore for 1/8 diff = $50 us
- 1 Dog Bone center kit from Kershaw = $ 55
- Bow ½ pvc (Fem to Fem) + 1” join = $0.50

First, I cleaned the diffs and put Gorilla Swat in it and change the 4 diffs output.

When I put them back together and tighten the ring to the cup, it was impossible to turn the diff by hands.

I noticed that the RC monster output was a little bit too long so I had to shave them to the appropriate length. Once shaved the diffs output, it worked perfectly!!

Next, plastic trimming can get started. It’s better to do it slowly to not take too much material at a time. I used this dremel bit to do all the work.

I hope the pictures talk by themselves.
A lot of small adjustments is needed to achieve a perfect fit.

Then I had to shave the drive shafts a little bit too. After that, it was A LOT easier to install the pins.

finished with RCM 8mm Drive cup - Kershaw dog bone

ps: I'm french speaking so my english is not perfect.

Very good writeup! This is a very good upgrade for the Traxxas trucks, the stock diffs are very weak.

Actually you already have that part, just need to cut of the threads.
that peice is in the the outers of the axle shafts in revo's, where your wheels are.

Very cool Tech, I'm buying some
I used LSt diffs in my Rock crawler with Ti Ni ring and pinion

1 other thing 43/13 is stronger than 45/11.
there is more tooth contact

its me Build is Frekin awesome , that thing is going to be a blast to drive
I', building something similar but more of a rally sedan

Sorry to intrude
but I am reading different stories on Hybrid diffs. not all the info seems to be there
Can someone tell me what exact parts are involved ?

I read about emax/revo bulkhead with LST Diffs
but I also read Muggy diffs ..? which is it.. confused
I greatly appreciate the help, thank u

WOw that's very cool,
Can you tell me what shocks you used here and how you like them ?


It's looks like they would be great for my 1/5 emaxx build in my Sig
Thank you for your time
Rian

Isn't the Aftershock Diffs the same as the LST ?

Aftershock, lst1 and lst2 all use the same diffs. They have 43t ring gears and 13t pinions.

The muggy uses 45t ring gears and 11t pinions.

All of the cases fit all of the diffs. So you can run al cases on a muggy and plastic cases on a lst. I would run al in everything, but I am having good success with the plastic case in the front of my emaxx. I have an al in the rear.

You also have quite a few options on the diff cups. I run nova rc alloy cups, but the 8t heavy duty cup looks just as stong, and a bit lighter. Stock uses a plastic cup, not the best for big power...

Ah all the diffs that im using are from either the lst or muggy.

Looks great

Care to share what new Parts these are ??

A Arms ?
Shocks ??

would revo arms fit maxx bulk diff bulks ?

[QUOTE=its me;160146]got some more parts in :) The motors are just for a stand in till I get the 7XL's from tekno :) Also got some flight power 4S 25C 5000 coming in from a good friend!!

Looks nice
Anybody Know what A arms these are ???

rear upper arms are revo uppers...

And the front upper arms are... nonexistent :smile:

paid a visit to LHS

the upper arms in the last pic that are placed in the rear of the truck are front revo arms (no str servo back there)

there are no front arms on front of truck

Why not list complete part info on a build thread, isn't that the whole purpose ? helping others.

BTW
Revo Rear uppers Fit Emaxx Front & rear uppers, unless there is some angle I do not see going to buy some verify that.

Heh.

We do like to help other people with their builds when ever possible, but we dont just build our own trucks for use as 'how-to' guides for other users who dont have the skill or initiative to complete their own vehicles.

Posting parts lists and # is a long job and most people dont tend to keep receipts or a log of every single part they've bought- especially if the intention was to build a custom one-off as a personal project.

If you look through the whole thread (yep, all 16 pages), you will see the truck in completed form pretty much- it uses normal maxx suspension essentially, just with the revo arms substituted in place of maxx uppers.

most people do not list part numbers, So certainly not expecting that.
Just a simple part name would do
like (picked up some Losi 8 shocks today)
( the losi 8ight shocks are almost a drop in replacement)
or (I dropped in some revo upper arms and they fit great)

I do agree that detail is nice when eyeballing someones build thread.

I am bad about build threads, I just post pictures of the finished product most of the time.

I leave out the fact that most of my materials are scrounged out of a dustbin... and other choice areas in town... Plus I usually leave out the fact I made 4 of whatever to get the final product correct (or maybe just close).

All in good fun, huh!

Actually the whole purpose of this thread was to show that the lst diffs fit in max bulks with very little work, sorry I wasnt more clear about it but the whole truck was actually a after thought.

No the revo arms do not fit on a t maxx, I modified the bulks to make them fit. You are basically the first person to ask about them, hope I answered your question.

reading this thread reminds me.. I forgot to send of the two MMM back to castle :)

we need more vid of the twin brushless truck:yes:

small udate

What are those shocks from? Never seen anything quite like it....

It looks like he just put an adjustment nut as a seperator; you notice there are no threads there? I did the same thing on my MBX5/Corr truck and Slash to reduce bottoming without making normal suspension travel too stiff.

Ooooh, dime-bar moment. :lol:

Home made dual-rate shocks, very cool.

I love the use of the extension plates for the longer shocks, real slick man.:yes: I wanted to try something like that to run OFNA rear shocks with my Pro-line arms.

Nice truck dude, I can see a lot of thought went into it.

Alien

Yup every one is right, there just revo springs with the retainer slid over the body of ofna shock. works better then I expected :)

UHH its mechanical brakes, hate to say it but if you read the thread 99% of the answers are there..
