If you want the lift to improve offroad performance, many offroaders choose Old Man Emu (OME) gear.
The boys who take this game very seriously indeed (and whilst I do a lot of competitions, there are others who take it far more seriously than me) often fit OME and I really cannot recall anyone having had a failure in these items. Google their name and you will find many testimonials to a good, strong and reliable product. As one site puts it "In the world of quality offroad suspensions, there's Old Man Emu, then there's everything else".
