Just for everyones info if you didn't know.I have a 86 Jimmy 2WD.I put in Bell Tech 3"drop coils in my Jimmy.I used #4227 Bell tech which are firmer because they are for a 94 and up 4.3.I plan on doing a V8 swap one day and Eric at Bell tech as well as my Bell Tech rep.said to use these because they are firmer than the 2.8 springs.I sell these for a living so I got the inside scoop.
