I have the JBG 5.5" leafs on mine. They come with rubber bushings so there actually about $150 less!
Mine are stiffer than id like but i attribute that to the huge arch in a 5.5" spring pack, and im running dual shocks. Someday i might try removing one shock, because when i used to drive it without any shocks it rode much much better! And agin if your used to driving a caddi like me everyday it dont matter what springs you buy for the bronco it will never be a caddi....unless you go rear coils.
I matched them JBG leafs up with there dever superflex coils and them coils are ausome!
