Gosh! these scene looks familiar with my XX4

So, whats the best way to prevent this? Keep the belt covers well sealed? What about diff grease, does it eat the belts? Get the tough belts?

They all seem to fall apart for any number of reasons.

I'm hoping the new belts for the 22-4 are better somehow.

I would blame the front one on dry rot of sorts as you can pull on belt and rebreak it no problem. the other 2 would be dirt buildup on pulleys and running little roller thingys. Last one would be again dirt and a slight thrashing by the guy behind controller

or the 6 feet of air

I raced a XX4 for quite a while, as long as my diffs and slipper were good, I never roasted a belt.

I did ask while at the iHobby show, and it sounds like the belts for the 22-4 are not the same length.

About the only parts that looked like there might be even a chance to work on the xx4 are the black rubber access cover and and perhaps the battery straps.

Too bad about the belts, but there is always a chance that something minor might be able to be changed to make it work. I just pulled apart a Street Weapon that had a XXT steel diff in it, with the Weapon rear gear. Maybe swapping some gears around might work.

Or not, either way, I'll see what I can do once the kit is out.

I've ordered some of the plugs to replace the horrible yellow ones I have on my SW and XX4

let us know if they fit as I need some too.

anyone running frt/rear sway bars? I have a NIP set that I may install during this winters rebuild

I just scored a baggy of xx4 parts! aluminum CVDs, steel CVDs, drive cups,, and...... trinity drive cup steel strengtheners!!! bunch more junk too.

Well I spent a good 4 hours wrenching time on my xx4 tonight, I love working on this thing. not really doing anything just tweaking.
Is there any news about the 22-4 parts fitting the xx4?
I installed rear sway and was wondering if anyone is running a front one.

I own both...and everything in the 22-4, while it looks similar, is not gonna work.

Still racing XX-4 even in 2019
