I don't know. That is almost a half pound of added weight to that rig. Makes it a little too top heavy IMO. Also, does the Slash really need one? I have yet to hurt mine despite who knows how many trips on the lid.
+1, A friend and I took turns beating the ever loving hell out of my new Slash this weekend. So far, durability seems to be REALLY good. Put $50 with it and get the Velineon setup instead.
