The LR3 / LR4 and Sport does really well as far as the air spring itself. The corner valves are a little problem and the compressors fail a lot till you update to the AMK brand compressor. In the full size Range Rover the 03 to 05 air springs are shitty and rupture all the damn time. After 07 things got a little better and you don't see as many air spring failures.
