    suspension - please check your ride and report back :)

    I have summit springs on mine front and back and the traxxas upgrade shocks.

    If i press down on the front, it bounces back alll the way.

    If i press down on the rear it will not bounce back. Stops about half way.

    On the rear i have the screw tightened so the spring is compressed yet the above happens.

    If i lift the car of the ground, indeed the rear wheels have stronger suspension and full range of movement.

    If i put a piece of paper under each front wheel and push down distance between front wheels remains the same

    If i put a piece of paper under each rear wheel and push down, the papers slide. The distance between rear wheels increases sligtly. So i believe this is why it does not bounce back up as easily because it would have to drag the wheels back together and with the wheight it aint gona happen


    IS THIS THE SAME FOR EVERYONE??

    I have A arms all around and HR knuckles, and traxxas pushrod, toe in and shafts.

    make sure your knuckles are not too tight. When i tightened the little hex screw on mine too much i received the same reaction from my shocks. If that doesn't work you could check your shocks for a leak and check to make sure that your drive shafts slide in and out smoothly (assuming that they are stock).

    That is not it.

    Loosened knuckles same issue.
    Not a leak either, they work very well just not when wheels on the ground.

    I have A arms all around and HR knuckles, and traxxas pushrod, toe in and steel traxxas shafts.

    The problem is that the distance between rear wheels gets larger when i press down. If i put wheel against the wall and my foot on the other wheel then i see an issue when i push down. This is not an issue on front suspension.

    Can someone test this on their truck?

    I think it has to do with the GPM Aluminum F&R Rocker Arm Set!

    It supposed to do that. It's just the camber changing

    Well, you are referring to something else!

    I am not referring to camber changing.

    Back is behaving different than front so something is not right. Will buy new rocker arms

    Mine is stock and does that. The way the back is made the camber changes causeing the paper to pull apart. It sounds like on you ride hight that the springs are to soft. I have 60wt with black on the rear and mine does that.

    Wow that's bright!

    I wouldn't have thunk of that...but consider that is the intent of the suspension geometry; is it not?

    Revo's seem to have a remarkable amount of what the manual (& industry) calls droop.

    That kind of suspension geometry & travel on a-arms inevitably increases/decreases the distance between the wheels; lest springs that maybe too bouncy.

    Having the 1-1.5 of toe-in on the rear may help bring the rear wheels back together, or at least help counter the effect of the rear dropping under acceleration.

    mine is the same way. the locations on where the arms connect to the bulkheads affects this. ive wondered it too but it never bothered me. when ur driving the tires will pull back together and go to normal ride height. i think that the top is shorter so when it pivots it pulls in faster. theres no way to fix this as its how the bulkhead is built

    But my rear suspension i feel is ridiculously bad considering i have the traxxas suspension upgrade + summit springs 2.77 rate. I had tried the black ones and did not work well for me. Besides the ones i have now are rated higher so they are stiffer.

    I think it has to do with the rocker arms since the summit ones are longer. As a result the suspension would need to work harder to push back... I have ordered new ones and takes about 3 weeks to get here

    I used front rockers in the rear to eliminate the droop or as I refer to it as squat. I also have GMP silver springs all the way around. This makes for a very stiff ride, but I drive mostly on roads and parking lots anyway.

    My front will not fit on the rear. Did you do that with aftermaket version or the stock plastic ones?
