    Bilstein Sports??? $50???

    I just picked up a set of almost new Bilstein inserts for my Touring ...

    I cannot tell if they are the Sports or HD or whatever. The shock shaft is almost as thick as the housing it sits in. There is an adjustment (i think) bolt at the bottom of the shock.

    Can anyone tell me the main differences between different models of Bilsteins???

      Look for some numbers stamped into the body of the strut or shock- should be near the bottom.

      Then just look at some of the online vendors who sell Bilsteins and see what you've got. Numbers probably won't match up completely, but the main numbers should tell you what you need to know.


      Turner Motorsports is a good source for these Part numbers...


      I have never seen a Bilstein HD or Sport that is adjustable- take a closer look at it to see what that "adjustment" part really is.

          Come to think of it it might be a screw that you use to take the shock apart for rebuilds and such.

          The reason why I ask is so I can find out if I need any special instructions on how to install. I've heard with the sports you need some welding/ fabrication as they are shorter than the OE strut housings.

              Not true, they are the same length. You DO need bilstein "collar" nuts though, stock BMW (or Koni or KYB or whatever) will not work with Bilsteins.

                  The nut you see on the bottom holds the shock in the tube, picture the rear shock with the yellow part polished upside down inside a tube.

                  The sports are shorter, but only internally (piston shorter than body or shorter overall with the Bilstein shock nut taking up the difference, I'm not sure) to make them survive with lowering springs.

                  Not sure what the difference is on valving between the two.
