Vehicle applications and ride-height settings
Height changes are relative to original equipment ride height: negative values mean lowering and positive values mean raising. Use the recommended range for your exact vehicle. The maximum adjustment range describes mechanical travel and is not a recommended operating setting. Actual height varies with vehicle condition and equipment.
