    Drive cup for 6mm output and 8mm bore dog bone?

    Hey guys need alittle help.

    I'm looking for some drive cups for our standard 6mm outputs on tranny and diffs that have 8mm bore so I can run 8mm dog bones.

    I hear the erevo drive cups are like this? Also are the rc monster cups like this?

    Links would help! Thanks!

    yeah i knew about those but i couldn't find anyone or anywhere that said they were 8mm bore on the dog bone side...so they are 6mm for the input shaft and 8mm on the dog bone side?

    The 5mm, 6mm, 8mm represent the size of the output/input shaft they fit on.

    My UE 6mm cup has a 7.91mm dog bone bore, my UE Ti bog bones have a 7.76mm end on them & my LST2 CVD's have a 7.83mm end.

    All of them have 3mm pins in the bones & the slots in the cups are 3.09mm.

    I do not have an 8mm bone to measure for you but I'm assuming it's pin end is going to be either 8mm or just over 8mm.

    Great info. I should be good to go. And yeah when I said 8mm I meant the size of the ball end.

    Thanks a lot really appreciate it!

    I have found that most rc parts have a bit of tolerance,s in them too. Got a couple 8mm ue cups that were oversize on the pinion holes and fit kinda loose. They replaced them for free.

    So guys, may I ask, if I buy 8mm CVD's from UE, do they need the 8mm drive cups, or do 6mm drive cups work with them? Pretty confused sorry

    You will need the 6mm drive cup's for the diff output's.

    The "8mm CVD" refers to the stub axle that the hex fits on, it's 8mm instead of the usual 6mm.

    That & the UE CVD's do not work with the new "Revo" style carrier, so unless you have correct UE arms/carriers(or the old type stock carriers) for them the UE CVD's are a waste of your coin(but still very well made).
    Look out for the tree/crunch!
