I've got 725# springs on the Radflows with TC UCA's... when I installed the UCA's they were really difficult to move up and down. I'm not sure if this is limiting wheel travel because we haven't gotten a chance to flex them offroad yet. Is there any mod of the tabs on the upper control arm bracket that needs to be done to free up movement or is this the way it is supposed to feel? I'm sure the tire puts more force on the arm than my arm. -Andy and Jo
