Trailing arms come in red anodized aluminum or plain steel (great for powder coat or paint). Because of the thinner tubing wall and reduced diameter, the steel arms are only 2/3 as strong as the aluminum (based on the critical load of a buckling column with an effective length the same as the maximum rod end bolt distance) but are at least as strong as the OE dogbones.
