i have all all quality crap in my suspension, and it still hops sometimes. not nearly as bad as with original bushings, but its not completely gone either.
there are a bunch of things you can do to reduce it, but it'll probably never go away:
solid rear diff mounts with collars (custom part- basically filling the gap between the crown and the diff on the rear mounts with a hockey puck or aluminum or whatever), subframe mounts, stiffer shocks, make sure theres no excess play in the diff
