The company that we use for our Bilsteins is authorized by Bilstein to apply the proper ends to fit these shocks to classic muscle cars. This line is known as their classic line as there are painted black. There is no secrecy here. The company's logo is on the shocks. They do not offer retail but sell through authorized dealers as we are one. If you have any questions let me know and I will answer them. All you have to do is ask. We price them fairly and include free shipping and on top of that we offer 10% off to the members of this forum. They are a quality shock at a good price and should be the last set of shocks you should have to buy for your muscle car.
Thanks
James
