Whats Up All!!!
New RB6 owner.
Working my build right now and I've built a bunch of kits but I'm having a hell of a time with the ball diff. Built to the instructions every step of the way down to having the washers in the correct direction but the diff wont diff. I turn it all the way in it gets to lock, I back it out a but and I turn one outdrive the other doesn't move (no diff action). I've carried out the whole process a couple times now and no luck so I thought I'd try you kind folks!
Any input is much appreciated!!!

so I'm really late to the party, been really trying to avoid it but i guess I'm going to bite the bullet and try shorty sideways. how big of a difference will 1mm make on the battery height? looking at the chassis it seems that 1mm will get rid of the ridges in the chassis. Im assuming a little more on the edges since it bevels just a touch? I was thinking of may just dremeling the sides and not even touching the middle of the chassis unless i need to. Has anyone done the shorty sideways and not have cared for it?

Well I figured it out and I wish I had something more earth shattering than just re building it and re building over and over did the trick. I'm guessing one of the rings just didn't seat all the way. something to watch for on the first re-build again!!! Thanks Again those who replied to help!!!

I ran then once last night, didnt change anything except shock ends to short and 27.5 droop using the inside hole. The rear end felt flatter, almost like you could drive the car a big harder overall. I don't think drilling is required on these arms but its worth a shot if you want to mess with it. I think have to go to a slightly softer rear setup as well. I was 32.5 and golds and I think white's would have been better or 30 wt.

Im not sure about the RB6 but when I ran my B5M on the astro we were going from the flat arms that we run on dirt to gull wings just for more steering. Not sure that applies to the RB6 but I certainly will try both when I go and see what I think

I would imagine your talking front arms which makes sense to run gullys for more steering. Kevin is refering to the rear arms which on the RB6 help the car rotate in certain situations. My experience with rear flats are they square up faster and are better if you have to run a softer setup for bumpy tracks without giving up on power steering. When i try to run gullys with a soft suspension the car gets really tight on exit.
