    From my research Ive heard so many mixed views on U joint drivelines.
    Some say that U joint setup doesn't work on Trailing arms due to binding during plunge. But the EBK kart seems to have done very well with Trailing arms.

    Im wondering how the EBK karts are doing with this setup?

    Im currently working on the same setup, Ujoint/trailing arm, on my Roketa LT conversion. Granted its only 35HP but tops out at about 50 MPH.
    All I have to do is get the Type2-930 CV adapters, then have the 1310 driveshafts cut down to size. Im hoping to get at least 14-15 inches out of the travel numbers to match with the front. Hope the Ujoint setup works out so I haven't wasted all my time and $ on gathering parts together.

    I believe EBK has had the dealer in th UK for some time.

    I am not sure where Bob has gone though, it appears his web domain has lapsed & someone else grabbed it & has it up for sale. Haven't heard from him on some of the forums either.

    Maybe another casualty of the recession?

    Bummer.From what I saw on RDC he basically got shut out of the Trophy Kart scene,at least racing anyway.It looked like he was doing pretty good with the larger desert karts he had though.

    Thats weird! UK!
    Yah I know his Karts were doing pretty good for sometime. Maybe the economy took a hit on EBK.

    Rather than starting a new thread, I'll dredge up this one.
    So I've got the EBK, it has plunging axles with U joints, I just had them rebuilt, the guy at the driveline shop said they are good and can handle about 22 degrees, right up to the point that they bind, so here's my question:
    the car has limit straps, they are about 2" too short if I want to utilize full travel capability based on using the joints until they get close to bind. this of course also makes the plunge of the axle quite a bit more.
    Anyone with experience setting up this type of axle? am I safe if I get some longer straps? it's a shame to waste 2 or 3 inches of potential wheel travel.

    So I just looked at another thread, seams like the big issue is plunge, if the splines stick and the suspension moves this puts a lot of side load on things, could bend the trailing arm?
    If it sounds like I'm answering my own question, I guess I am but need some further advice on this.
    I should not push my luck with increasing the travel/plunge, if I want to upgrade to CVs then more travel is available.
    Question, why is plunge in the u joint axle any different than the plunge in a CV axle?, is it that the CV axle plunge is shared on both ends?

    "I should not push my luck with increasing the travel/plunge"

    I'd go with this.

    Im not the expert but I have read about before. The CVs plunge on the balls up to a point, then the splines take over if they have too, but that's not ideal.

    Think about the splines on your axle trying to slide with a huge twisting force on them. The twisting tries to keep them from sliding, making the suspension act different.

    So balls versus splines! Balls always win!

    Bull, sounds like you're telling him he doesn't have the balls to increase his travel. hee hee

    Add to that the big increase in diameter for the sliding spline means far more shock loading going through the rest of your driveline.
