My Leafs are flat as a pancake....

Is that normal? I mean, I don't know what they should look like if they are new, but I know the leaf springs on my dodge ram were not flat. People talk about sagging, but in order to notice sag you have to have something to compare it to. Since I just got my jeep I am not sure if they are supposed to look like that.

If they are sagging, what is the best fix? A new set? How about just a set of add a leafs?

Mine on the 90' where pretty much flat. I still managed to fit some 31 bfg ats on. But the black diamond lift on our 89' has alot more arch then the stock leaf springs had (obviously). I would guess to say that the majority of stock leaf springs will be relatively flat or have just a small about of arch, after 20 years of use. I doubt they came with that much to begin with tho.

Maybe its time for a lift?

What you could do, depends on what you "want" to do
I had add a left on one of my toyota trucks and it worked nicely so as to not to sag in the rear.
If you were to get a new set, In my opinion, you should consider getting a small lift kit. Get new shocks (those alone could make a world of difference if yours are oem) and and maybe a 2" lift set of springs.

Guess it really depends on what you want to do with your jeep.
Use the search and the picture forum if your curious what a lift would look like on your rig.

Stock YJ springs from the factory had little to no arch in them.

I always wondered this too, Mine has 130k on stock leafs so I just thought they were saggy. I'm going to a 3" lift when I get the money though

If you are handy with a wrench, can scrounge a pick 'n pull yard, and have an afternoon to kill, do a bastard pack lift. Worked wonders for mine. Can do both front and rear the same way, but in my case the rears were totally flat with some arc left in the fronts so I have only done the rear so far. I am doing a 75% driveline swap (scout dana44 front axle/nv3550 trans/dana300 transfer case) this summer, so I will do my fronts then.

I am hoping the stock springs I just picked up are nice and flat when I go SOA... better ride and flex. High arch = stiffer spring and less flex.

And 89-yj... SOA with 3.5" lift springs is going to put your wayyyy up in the air. Guys run 42's on SOA yj's with 1.5 and 2" springs.

I read through a few build threads and i see guys running soa with 3in springs and 37's. I dont know how to get 42's on with out completely hacking your fenders...assuming you want room to articulate.

highline tube fenders and comp cut and you would be good to go. You dont need a ton of uptravel, maybe 4-5 inches max, it is the droop which means the most. 3" springs are going to be pretty stiff and not flex nearly as well. But some dont really care about flex, just wanna clear "big tires"... so I guess it is all preference.

There is a local junk yard really close to Akron, Ohio called MARS . They have a yj wrangler with 3" lift springs for $55 a spring, if you are interested in a used spring lift.

Currently my stock suspension springs sit about the exact same as everyone says... flat, or the slightest amount of arch. Mine has the 4.0 and a hardtop too, so I know mine aren't too worn cause they're not inverted .

I have 31's on it and They rub when I drive on anything rough at all, so until I lift it I'm stuck on the road
