I totally agree with you. There are over 3,500 different grades of steel, encompassing unique physical, chemical and environmental properties. The solid I was referring to was the common A36 we use on a daily basis. And I agree that it all depends on the steel. Example: I put a 1/2" solid rod of A36 into a hydraulic break and bend it quite easily. The same 1/2" DOM tube will take more pressure to bend, even with the hollow space inside. Try to bend the same 1/2" solid rod of tool steel and it will snap.

All I was stating was that the DOM is adequate and comparable to using solid steel, but no one uses solid steel because of weight, when a tube can get the same results. Even a low grade carbon when cold drawn will gain much more strength from compacting the grains. Same can be said with aluminum. I've cold drawn and annealed aluminum tube to a hardness comparable to the same wall thickness of SS tubing, all in the name of weight and cost savings.

The DOM used on the Allstar Performance tubes I used have been tested on the Modified Dirt and World Of Outlaw racers with great success. And that is some kind of abuse for suspensions.
