The kit I just took off my truck was mcg spindles, djm torsion keys, djm shackle and hanger and replaced overload spring with one from a ford.
There are pros and cons to every manufacturer, so I pieced mine together to get "what I think are the best parts" it all depends on what you are willing to deal with and what you use your truck for.
