I have the rough country 4rcx flex kit with quick discos on my 2002 overland 4.7. It's been fitted for around 3 months or so, since then I have been onto rc and have had to have replacement shock bushes, replacement steering bushes, replacement rose joint and I'm currently waiting on new bush rubber for the control arm flexi joints. Seems to be nothing but trouble and bad quality materials. Rough country are happy to replace the parts with newer upgraded ones. But damn it been a hassle
Anyone else having these problems?
