Heim joint extended radius arms

[XploreAlaska]

Okay so I checked out www.rustysoffroad.com for heim joints, found rubber ones and the standard steel ones, anyone know which one might be better for this application?? Any better sources for heavy duty joints?? I'm not about to spend the extra cash for longer arms when I've got a chance to extend them myself.

Since there all the same price I'd go with the steel ones.
