If Sachs was building these shocks for them, the stickers would not be on them. They are going to start with new, fresh casings and then install the internals, not take a freshly built shock and take it apart to change the valving. Since they start with a fresh case there are no stickers on them. Most shocks are made by a few companies, so you shop around with who will build them to your specs at the best price, but you won't find two stickers on them. My second guess is since they're coming from Germany, anything aftermarket needs to be TUV approved. Guessing that they don't sell enough to have to pay for each shock/strut part # TUV approval, therefore the need to use something that is approved and available. I'm also thinking they don't make the springs either, if they did I'm sure they would be sure to make mention of that. I don't see anything that says they make any of the components in house. Manufacturers that do, usually make a point of saying they make all or most of the things they sell. by the way, I've worked in the aftermarket industry for many years and find it very odd that they would leave that sticker on there.
