question about the leaf springs, OEM

i have some lean in our CJ that i want to correct and would like to get this thing to feel a bit more stable at 55 mph. currently the rear has 6 leaf and the front has 4 leaf. is this a normal configueration?. it leans to the left slightly and i will be simply replacing with stock components "no lift". shocks, bushings, springs, sway bar links. should it be 6 and 6?

Some one will chime in on the count.

A spring shop can correct the leafs to speck. Also google YJ springs, lot of guys like that ride.

I lucked out and grabbed some from a buddy lifting his.

thanks for the info

i figuered the lean was OEM AMC design?. anyway, the YJ upgrade would be nice but i dont want to mod the front hangers. this is a 100% original jeep other than front seats which i replaced and threw the old ones in the junk yard?, im still regreting that!. ill order the springs on monday and keep the 4/6 config. thanks!

I ran 4 front and 4 rear on mine. But also have a fiberglass body, no top, and built very light (light weight bumpers, etc.).
My current YJ springs are 4 in front, and 5 rear.
It has a nice soft ride, but when loaded down with camping gear, it will sway a little in the corners.

It all depends on your weight, and what type of ride you are looking for.
Here's a chart with the spring ratings for the different spring packs.

Leaf spring count all depends on what the Jeep came with as it left the assembly line. 4 leafs up front could be a 4 cylinder engine or factory 'so called" soft ride. 6 leafs in the back indicate you have a factory hardtop with steel doors? Without hardtop, usually only 4 or 5 leafs.

Yes, factory hardtop, 6 springs in rear on mine.
I do have the 4.2, but from information you provided Keith, with my stock 3.54 ratio, it came with the 4 cyl?
She does ride very nice, not bouncy, etc.
Though when I replace springs in the future, I will probably go 6 leaf front with the winch.
Maybe up the rear to 8 with the aftermarket bumper/tire carrier, about 60 lbs, spare, about 55 lbs, a tool box always carried, another 60-80 lbs.

For 1983 model year, the standard gear ratio for the 4 cylinder engine would have been 3.54 with a 4.09 as an option. 2.73 standard on the 6 cylinder with a 3.31 as optional.

That's what I figured out Keith. Wish I had the 3.73, for my use would be perfect, but oh well.
Ocerall it runs good, spring arch still good.
I noticed/commented on the jeep lean in the brochure post from Overland magazine. It makes sense in a way, they used to crown dirt roads more years ago.

ill stay stock at $100 each from morris 4x4. will the "lean" likely be corrected with the new springs or will it require shimming?. somewhere on here im hearing shims are required on one side in the rear to correct a factory flaw?. thanks for the info and spring chart.
