There is nothing suspicious about it. If you have our catalog or have been on our website you will see our Bilstiens come from RCD. They purchase Bilsteins as blanks. They fix the proper ends to them for the applications that we request.
We also carry a higher end shock which is built by Vi-king which I feel far out exceeds the fox. It to is a smooth bodied aluminum shock but is double adjustable with a stainless steel rod.
Thanks
