Not to be a know it all but do not buy radflo's without ucas that have a built in extension/ rebound stop, radflo's are not designed to limit suspension extension and you will have a very harsh thud / f....d ball joints before you know it, every time your wheel drops over an edge etc.
Cheers, jus from experience, correct me if I'm wrong.
BTW, Good luck with your email, you might as well piss in the wind. Order something than let it go to a PayPal complaint then you will get an immediate answer. Awesome gear though. Just do your research on frontier forum though,IMO, get the PRG arms OR Total chaos and use offset LCA bushes.
