What are the condition of your torque boxes. What UCAs are you running? Do you have rubber bushings in both ends of UCAs? I’d have to agree with others here and doubt that it’s the LCAs that are the culprit. I’m running the same ones with FRPP uppers, Tockico blues and Steeda sport springs and the ride doesn’t feel any harsher than stock and I have no clanks that are noticeable during normal driving conditions.
