I have been searching for some time for parts like these (with no success):


But with two holes (instead of three) and one socket for Lego axles at one side.


Likewise two holes (instead of one) and one socket for Lego axles at one side. So does any of the above parts exist?

enter image description here

What I am trying to do is to make the roadwheels of the suspension more sensitive to movement. Now the Lego sword blade goes through the axle hole of the 3l liftarm, but that creates a lot of friction and the roadwheels won't spin with the tracks. If the brick I was searching for existed, I would attach the roadwheels to a Lego axle which would go through the round hole of the liftarm generating minimal resistance. But anyways...

Do you guys have any better ideas?

I can't see a lift arm with two round holes and one axle hole on the same plane, but there is one where the holes are perpendicular

If you have the space you could try joining a standard 3L arm to one of these

Updated suggestion Now that I see what you're trying to do, have you considered one of these


It's 4L but the extra axle hole would be concealed by the wheel, and the wheel would have it's axle through a pin hole and spin freely.

  • Thank you very much for your suggestions, unfortunately I have already tried the 4l axle and the extra length collides with the tracks, the wheels won't be able to sit properly on top of them, I will accept your answer anyways because such brick does not seem to exist, thank you!

Not sure if you’re still working on this build but easy answer,

If it needs to be able to not pull apart and if height doesn’t matter above the wheel this is also an option.

This is the skinniest version that I’ve posted you can reinforce it so it’s more securely anchored to the axles rotation by making it thicker like this,

You could modify the 4L. By chopping off the fourth /end-slot you should now have the right amount of plastic in the right places.
