There are several manufactures that make roller rockers from aluminum. The other option is stainless steel. One word of caution if you choose aluminum. The method by which the roller tip (axle) is retained in the body of the rocker usually entails inserting a hardened axle pin that is knurled on ONE end into the machined hole at the tip of the aluminum body. The constant heat cycling and beating that the tip incurs through normal usage will often times allow the knurled pin retention to be compromised and it can slide out of the body allowing to roller to exit the rocker body and potentially cause serious damage. If you choose aluminum check them often, and watch for any movement of the roller tip axles. This is just my opinion, but I have seen the resulting coinsequences of long term use of aluminum rockers on the street.
