the rpm arms are a lot lighter then the aluminum arms out right now. The only downside that the rpm arms have is that they got a lot of flex in them. That is the one reason why there so indestructible. For bashing there the best arms money can buy, for racing i would stick with the stockers. Dont go aluminum if you are worried about weight, your truck will probly gain like 2 pounds or more with just arms. Wait till UE comes out with arms or dace. They make there products out of 7075 which is light and strong.
