Same question, Bob---my stock were junk from the get go so at 18K miles I went with the group buy on bilsteins and she rode like a cadillac for some time but at 53K on the clock the ride sucks---just did the old knee on the bumper test and she bounces as if no shocks are present!!! Does the lifetime warranty cover completely worn out in 30K miles?? If so, how to get them replaced under warranty---truck needs to go everyday so sending shocks back and waiting for bilstein to test them and decide wether to warranty or not is not an option.
TIA,
Jerry
