Please remove all springs (unless you want them tested) and mounting hardware before shipping.
If you do not have tools to safely remove the springs yourself, please ship them assembled. We will dismount and remount them for you. There is a $12.50 per shock charge to remove and reinstall springs that require the use of a spring compressor.
Please include a note with your contact details and any relevant information pertaining to the shocks and your vehicle.
