The 3" BDS lift kit with leaf packs is over $1000 on their site. The 4WDH version would be much cheaper if that's true. I've also heard ProComp may be the makers of their kits.
it rides stiff.... but the springs have yet to sag after 3 years. I have had a good relationship with pro-comp and their customer service.... I kinda wish that I had saved some $$ and gotten springs from them instead of RE... I didnt notice a difference between the 4wd ones I got rid of and the RE springs I put in..
I also wheel with a guy running 4" procomp springs on his TJ... flexes like a Mofo.
I liked my 4wd kit, it was great for a cheap budget boost and it let me haul a ton of gear halfway across the country without hitting the bumpstop in the rear..
the shocks suck, but they only cost 20$ so what do you expect...
I worked at 4WD, 5-6 years ago they were made by BDS, but that could have changed. The only complaint I would hear is the spring were stiff until they broke in which took a while
