Aside from loss of flex, and a crap ton of fabing.

Pros:
Simple setup once it's all done
Probably stronger

Cons:
Setting it up
Setting caster angle
Leafs are more expensive
Not as much articulation




Dunno, can't think of much else.

here's DaveVmax's https://www.cherokeeforum.com/f54/co...vevmax-106774/

cheap as dirt using ruffstuff shackles and some JY bastard packs
other pros are delete your track bar, set perfect shackle angle, stretch wheelbase
cons I imagine would be ruined approach angle and setting up your steering. I'm not sure how you'd get a tie rod on there without histeer

stength is debateable. caster would be easy. same as setting a rear axle pinion angle with leaf perches

Just a few reasons I love leaf springs. This is my opinion and is based on my experience: Stability. Stronger when done correctly. Acts as a slider to shovel the axle over an object if done correctly. Spring rate is easier to tune/adjust without spending a lot of money. Can flex as well as any coil or coilover when done correctly. Easier to setup and stretch wheelbase. Easier to adjust pinion angle. Easier to bumpstop after setup (no need to pull coils). Wears out faster than coils when flexed too much (sag-depends on materials). Doesn't look as "cool" as coils to many. No trackbar is necessary. No control arms are necessary. Cheaper and ubiquitous parts (i.e. bastard packs). Capable of carrying much heavier loads without sag (at the cost of flex). Bushings tend to last longer than control arm bushings (depends on quality of bushing materials and tolerances of spring eyes/shackles).

why go backwards when what you have is already there and easily upgradeable

Probably depends on the amount of arch. It would probably be advisable to run a track bar. YJs have them too. Just give it a quick disconnect or something when offroad similar to the sway bar??

To weigh in on the OPs original question, I think that the benefits would never outweigh the drawbacks of converting the front to leaves. Even upgrading to a long arm would be simpler than doing all that work to put it on leaves...

there is some info in this thread for the both of you
http://www.therangerstation.com/foru...d.php?t=103172

as for long arms being "simpler" or "easier" is not for you to decide. if you're afraid of a little welding and cutting then yeah probably stay away from it. but some people enjoy the work

is it "worth it" is up to you. I still think you'll be pressed for space on a D30. why don't you price out all the bracketry, shackles, leaf packs, and steering and weight that against the cost of going long arm

My friend had a samurai on YJ links, the approach angle sucked but it was also a spring-under setup, spring over would have helped with that.
