This is a good question and I’d like to know the answer too.  I have a 4” JBA kit from before there were silver/gold/etc. options! My shocks are all still going strong at the moment but it’s good to have a plan for the inevitable. I know they’re Bilsteins but that’s it at this point. 
I figure JBA will still exist when they go so I was planning on giving Marlin a call at that point.
