This is a review of the Lexus Gx460 B5100 lift with old man emu springs (medium duty). the springs are rated for 100 to 300 pounds of constant weight. with no weight (bumpers winch etc) there is approximately 2.5 inches of lift loaded up, and it would be 2 inches. no upper control arms are necessary when lifting 2.5 inches or less. there is no bump steer, and the steering wheel still feels weighted.
