Rubicon Suspension under a YJ

I've got a buddy with a Rubicon that has upgraded his suspension package and has his old springs and such sitting around. Would these fit underneath my stock 1992 YJ? I'm really only looking for enough space to get a little more meat on the wheels and tires. I'm sure it's a long shot but I figured I'd through the idea out there for the experts' opinions....

Only if you want to convert your YJ to coil springs, not really cost effective though. Short answer would be no.

The Rubicon is "special" mainly because of the D44. You have leaf springs, be thankful. Coil springs get more flex sure, but for 90% of us, that extra flex doesn't mean squat. They also get this deal breaker known as deathwobble. My 91 YJ is way more solid than my previous 97 TJ

They also get:
A better ride
More controlled flex
No axle wrap
No broken leaves

Death wobble happens to a TON of leaf sprung rigs.

Hey, I like my bouncy YJ! Drives like a Jeep should. In my opinion, I've owned both, the YJ is a better Jeep. Easier to repair and just plain stronger, but you're missing the point of the thread

Definately, it's not just a Jeep or TJ issue.

Hmmmm I am pretty sure the so called death wobble is special only to coil springs. I don't believe it is possible to get death wobble on a leaf spring set up. I think there is a lot of misconception about death wobble and what it really is.

Exactly, only TJ owners know that pain. YJ's might get shimmy from unbalanced tires, ball joints and tie rods, but it's nowhere close to the sh!t your pants "Oh god I'm gonna die" death wobble from the coil spring track bar control arm combo and eventually it will happen to every TJ when one the 5 main bushings in that setup fails or becomes even slightly worn. Been there done that, I'll keep my leaf springs thank you

Do you have proof of this? That is a pretty bold blanket statment, that happens to be false.

I have personally had death wobble on 2 different rigs. Im not talking a shimmy or shake. I mean full on tire oscilation from left to right yanking steering wheel out of hands.

There are TONS of threads of people with leaf rigs with death wobble.

Wrong caster setting, worn out tierod ends, out of round or out of balance tires, bad balljoints, worn kingpin bushings, bad wheel bearings are all causes of Death wobble.

Is this not death wobble?



or this?

Jeep Death Wobble And How To Solve It - Jeep Parts and Accessories

Or I could just take your word for it. Either way it doesn't really matter. You can be right if you want to.

I wouldn't consider a tire out of balance death wobble though.

I didnt say an out of balance tire was death wobble. I said it can be a cause of it.

Death wobble is caused by the oscilation of the wheels from side to side. An out of balance tire can start these oscilations.

So those 2 trucks in the videos i posted on leaf springs are not showing death wobble according to you?

It is not a jeep or coil only thing.

ANYTHING with a single steering pivot and enough play can have this issue.
