I have a 1996 4.0 N/A Sovereign so they should be the softer BILSTEIN B4's as I can see the Bilstein sticker but not the model number . In order to bring them back to serviceability I wish to air them up to the proper air pressure before I was to overhaul them with new internal porting valves and seals . But I can't find the schrader valve to do so as I would on aircraft landing gear struts . Did these not come with a servicing schrader valve ? I understand the unloaded air pressure charge is according the Bilsten documents is between 180 - 200 psi . Motorcycle shop should be able to do this without buying the 193000 servicing tool . Somewhere I get the understanding they are 7100 series and they show the schrader valve and that is the key even to be able to overhaul them . I don't see them on top under the rubber boot . My upper bushings need replacing as well . Front 24-018616 rear 24-015886 are the new numbers are the old numbers the 7100 ? . Overhaul kit # BSN B4KT0Y013A00 Summit Racing .
