SMB Posted June 28, 2021 Share Posted June 28, 2021 I would like to find out the correct size shock absorber for the 37 Presidents. I replaced them when building the car but don't believe they are doing the job as they may be the wrong working length. I would appreciate some suggestion as to what others have used or how to determine the correct size. Link to comment Share on other sites More sharing options...
studerex Posted June 28, 2021 Share Posted June 28, 2021 I would check with the studebaker museum for the shock print. If they have the print it will show the collapsed and extended length. Maybe the supplier and number. Link to comment Share on other sites More sharing options...

John DePrey Posted July 6, 2021 Share Posted July 6, 2021 First choice is get shocks from a supplier that are correct. But thought I'd answer the question... if you dont have compressed and extended lengths another way, measure what the compressed length would be with springs hard against the stops (a little geometry is required). Disconnect existing shocks and Measure extended length by jacking car up by the frame and let things hang. The compressed length is more important imo, don't go any longer than what math tells you. You'd rarely reach the extended length as measured above. Sometimes that is what helps control spring extension at extreme unload, I just dont like seeing much hanging-from-shocks on the lift.
