No instructions but that's ok. It's not to terribly hard to figure out.
I had to disassemble mine and change some things around to get it to work on my SCX10 Deadbolt.
But they give you all sorts of spacers and bolts to set it up the way you need it.
Installing it is sort of strange. It just slides in between the frame rails (you need to remove the bumper/cross members).
I used a couple of zip ties to lock it into place.
It looks great and works very well. Just pay attention and put your steering rod on the same side as where the panhard rod connects to the axle.
