Been reading that YJ springs ride better than CJ springs.
They do but they are becoming somewhat rare; I used the I-6 YJ hard top rear springs, (extra leaf, 5 total if I recall correctly) in back on the '81 -5. Some 5s use narrower springs & frame mounts (require mount bending or wider rubber shackle end frame bushings). Some earlier 5s used shorter springs especially on the front if I recall correctly. Be sure to try them out well before relying on them for a long trip (I have come out of difficult trails on the bump stops after installing what I thought were YJ springs, might have been 4 cylinder ragtop springs or even front 4 cylinder (bought a local 4x4 shop's spring pile once).
I found that after a few years stock YJ springs become w shaped and need to be replaced if used hard; lockers, 456s, 33s or 35s, on trails like Pritchett canyon in Moab.
Enjoy!
