Aren't we talking about the rocker arms on the Revo? Rocker arms aren't the same as suspension arms, they just transfer movement from one direction to another. In this case, up and down suspension arm travel to in-and-out travel of the damper.
If meme405 is looking to get aluminum rocker arms for his Revo, by all means, go right ahead. If it were actual suspension arms, then I wouldn't recommend it.
