Leaf springs are cool for old Jeeps but they don't work as well as coil springs do for offroading. And they sure don't ride nearly (!) as well as coil springs do. Put it this way... there are a lot of people converting their leaf spring suspensions to coil springs, and there are commercial kits for doing that too, but not the other way around.

What about the advantages/disadvantages of our straight axle vs. IFS other than the "pumpkin" on the IFS having more clearance?

Yes and no. A properly done SOA on a YJ will ride just as well as any TJ and in most cases will outride one. Its always gonna be an argument whether coils or leafs are better offroad. The biggest thing you have to take into consideration is what kind of wheeling you do. For 80 percent of the people leafs are just fine as they never push their rig to the limit. The biggest problem with the TJ's suspension design is that its prone to death wobble and is expensive to modify and maintain.

I can't argue with that but I'll add that 100% of the vehicles I have personally seen at the two years of the King of the Hammers offroad race and rock crawling event I have attended or helped build a vehicle for were running coilover suspensions. Not a single leaf spring vehicle to be found.

Stock coils vs. stock leafs= coils
Good long arm vs. good spring over= coils
Cheap 6" short arm vs. good spring over= leafs
The only real pro I see to leafs is the simplicity. I can still wheel with a shackle hanger ripped off, but you'll be dead in the water if you lose a link or link bolt. Coils are usually superior, but leafs can be made to work quite well.

Not my rig but it shows that properly setup leaves will get you anywhere coils will. This CJ went all the way through Sunbonnet in JV unwinched including a couple of spots that a few on coils had to be tugged. Of course a good V8 and 37's (IIRC) help too. Slick rig!
