I could have bought any lift kit available for my XJ when building it. After meeting the owner (Rusty) at the dixie run in tellico. I think it was october of 2005, I bought everything I could from them (9" coils, longarm kit, steering kit, track bar and HD mount, steering box brace, trac bar brace, brake line, shocks, shackles, etc . I feel and having owned it and used it for years, it was a good choice. I think the people complaning, abuse the hell out of things, and get pissed when they brake. I have not broken a thing that has come from Rustys and have only good things to say about what they build.
Of course this is my experience, not all are the same.
