Of course I'll recommend UPR, but regardless of which brand you go with, I'd strongly recommend upgrading to tubular a-arms and coilovers. If you still have stock a-arms on a fox, it's almost guaranteed that the stock bushings and ball joints are very warn. In my opinion, it's not worth the effort to replace the bushings and ball joints in the stock arms. It's better to just upgrade to tubular. Two cents.
