Yeah... they look really Wide... That is weird that anyone would make them like that. Especially RMS who I have heard nothing but good about. Let me know what you find out!
Are these RMS tubular uppers the same part number used on the Alterkion front ends? If so, those are setup to use coilover spring/shocks that need room to go through the upper control arm. But again, I'm not sure the Alterkion uses these same uppers.
