I am in the process of building a custom coil setup on my trail Jeep. I was wondering wich type of steel is necessary for the locating arms and the like. I know alot of guys like to run thin wall Chrome-Moly for weight savings, but is the expense really worth it or should I just run a slightly thicker walled DOM mild steel. Weight isn't that big of a deal to me but safety definetaly is. Will heavier DOM mild do the same job as C-M? My rig is Right at or under 4000 so it isn't a heavy vehicle. Cost is a major concern and I have heard that chrome-moly is extremely expensive. Is the difference that great or is it small? If the price difference isn't as great as some people make it out to be my vote would definetaly go to the chrome-moly. Thank You.
