Bilstein label on the shock body should be upright.
The Bilstein label on the shock body should be upright and readable when the shock is mounted on the vehicle in the correct orientation. If your shocks have been installed with the labels upside down they should be re-mounted right side up to insure optimum performance and warranty. Be aware the boot could be up or down but the label on the shock must be upright and readable when mounted on the vehicle. This does not apply to off-road racing shocks or motorsports shocks.
