I need to change out my tired springs (86 CJ-7 w/springover) and am thinking about converting to stock YJ springs. Probably would go with rears in both f & r. It has been recommend to me that an add-a-leaf greatly extends the spring life in this type of conversion. Interested in feedback, articles, etc. on CJ-YJ spring conversions. Thanks.

This info has been discussed many times here and on other websites. Change your browser to show posts for the last 90 days or do a search on SOA springs or YJ springs. You'll come up with lots of info. There's a post just below yours about spring wrap which will have some info on it. The tendency is that YJ springs tend to sag and have springwrap problems. Others have no problems. Each situation is different though and your results will probably differ from anybody elses.

Go with aftermarket YJ springs. They will last longer. <IMG SRC="smilies/biggrin.gif" border="0">

I've had stock YJ rear springs in the front for a year and a half on the 7' and have no sag/wrap problems.

I noticed that my rear CJ springs were about the same length was the YJ springs I have laying around, so if you think that YJ won't hold up.

I also did the conversion on the SUA scrambler. I used the 6 leaf military wrap rear CJ springs, the existing front ubolts, rear ubolt plates and rear shackle hangers. Had to do some grinding on the carrier to fit the larger ubolt and had to grind and pound out that rivet on the frame to fit the rear shackle hanger.
Though SUA, here's a pic of the scrambler:

If you do a search there is an excellent article on here about a SOA on a scrambler. I did one on my 7 with stock YJ springs and after one weekend of mild wheeling they were all flat. Took it to the local spring shop where they re arched them +2" and added a leaf. Have had it for about a year since and have not experienced any sag, yet it flexes awesome. This is after three trips to Moab, One to Colorado and numerous local outings. FWIW
