Jeep in question is an 89 YJ 2.5L 5spd, SOA, 1" shackle lift, stock axles, 33x12.5's. Softtop, half doors. 95K miles. Mostly used on trails in the PNW, some daily driving. I finished the spring over late last month, and have about 2000 miles on it. I absolutely love it.

Unfortunately, I knew that when I went SOA, I would destroy my stock spring packs. Front mains are bent to crap, rear packs are sagging with bending mains. They were pretty much toast before I started, so I picked up another complete set. I am about to get my hands on another good set. The set I have yet to get apparently has all perfect main leafs. The extra set I all ready have has all "decent" main leafs. My plan is to cut the spring eyes off of the main leafs from the first set of spares, and add those main leafs to the second set of stock spring packs with good mains. This would result in a 6-leaf pack.

Should I remove the small leaf at the bottom to go back to 5-leaf packs? I don't tow and don't generally carry a heavy load.

While the packs are apart, should I taper the ends of each leaf?

I'm hoping extra main will help fight spring wrap and sagging without giving much more lift. Will the added main do the trick?

I've heard that not using leaf-spring clamps can improve flex.. Is this true? Aren't they necessary to prevent lateral movement of the leafs?

I was checking out my stock packs today.. The front only have 4 leafs, and the rear has 5. The first used set I have are all 5 leaf packs. I need to gain a tiny amount of clearance on the passenger front for the drag link below the spring. Can I cut one of the small bottom leafs to the length of the spring perch and add it to the packs to accomplish this? Will it stiffen the packs? Can I use two of the above to gain a little height in the rear (I don't like the sagging rear look). I would just switch the front and rear packs, but I don't know which are which.

As an alternative, I have considered buying Rubicon SOA springs; are they worth "spring-ing" (ha ha) for?

Thanks for any help..

There is a section for this kind of Newbie Tech.
If you are remotely heavy on the gas, leaf springs alone WILL NOT save your drive shafts. You will need some sort of traction aid. Ask me how I know. Just run the stock packs, the flatter the batter.

the extra main might help a little with wrap, but its definetly not the solution. try running them as a 6 pack first. if you dont like it, get rid of one.

rubicon springs might help, but again, not the solution. sounds like you need wrap bars at the least.

When I did my spring over/full width conversion this is what I have come up with so far:

Front: Stock YJ spring w/ the main out of a 3" lift added after cutting the eyes off. Leaf retainers cut off, no anti-wrap solution, no lowered bump stops.

Well this worked for awhile. When one of my front tires would drop into a ditch all of the strain was on the main leaf (due to no retainers) as they spread apart. Thus my fronts are tweaked and of course with no bump stops they would get negative arch.

Rear: Stock YJ w/ 2" Rancho add-a-leaf. Retainers cut off, traction bar, no lowered bump stops.

So far so good with this setup. I have since lowered my bump stops in the fron/rear, replaced retainers on the front and am planning on replacing the fronts with the reverse eye Rubicon SO packs.

My .02 towards the topic.

I am running YJ packs beefed up. I think I am at 7 or 8 leaves, all the larger ones (main w/o out eye etc). I even mixed in CJ rear leaves since they are basically the same. I do have an anti-wrap bar, lowered bumpstops (very little up travel, but prevents negative arch) and spring clamps bent apart into a U shape (holds some lateral movement).
Works well so far. I plan on alcans later though.
