    RPM arms & CVD compatibility

    Hi,

    I'm soon going to start on a new ERBE build, and I need to know which CVDs are compatible with RPM arms and/or axle carriers:

    1) Traxxas steel CVDs (5451R)
    2) Summit plastic CVDs (5656+5654+5653)
    3) MIP Spline CVDs
    4) TVR Ball-X CVDs
    5) Am I missing anything?

    Thanks.

    Go for the summit axles. Bolt up fine and hold up better

    I'd skip CVDs and RPM arms. I've heard a lot of things about CVDs partially popping out or bending because the RPM arms flex so much. I'd suggest summit shafts.

    I use the X-Spline CVD's from MIP they work just fine with my RPM TrueTrack.

    Wait, so do I need long or short Summit CVDs for use with RPM arms? I used this article as a source of necessary part numbers.

    And are Summit CVDs compatible with RPM axle carriers? How about Tekno?

    Thanks.

    Iv been using my trx cvds with rpm arms for awhile and havent had any issues. The trick is to make sure your pillow balls are screwed in all the way

    The Summit shafts will work just fine with the stock knuckles, they are the same on the Revo & Summit..

    The long & short shafts, the Summit has a locking diff so one side needs a shorter drive shaft.
    If that bugs you just buy two sets & sell the shorts or try to find just the longs for sale.
    I run the two shorts in the rear, will not hurt a thing.........

    Honestly... I'm not sure I want to go with Summit CVDs shafts any longer. A full set would won't cost me much less than MIP Spline CVDs, and those, at least, I can be sure will last be a long time.
