My 88 YJ rides like a rock!

My 88 YJ rides extremely rough. I installed new Sky Jacker softride shocks but that only improved the ride slightly. I suspect that the leaf springs are not stock or possibly shot. How can I troubleshoot this?

Some lifts, add a leaf springs can just be rough like a wagon. Tire pressure is massive as I've learned recently. 20 psi to 45 psi it was just nasty. That'll shake the living crap out of you.

Trac bars. If you have them on, try riding with them removed.

Thanks folks!I did lower the tire pressure but I don't think I went low enough, I'll try some more. I did discover one thing the other day, I was hauling some sound equipment for our band (3 good sized amps and some other misc sound gear) and what a difference some weight in the back made! I thought I might throw some sand bags in the back unless somebody has a better solution.

I say your leafs are poo poo. There's a big difference between cheap and quality springs in terms of ride comfort and performance.

Sent from my phone because I'm doing something "more important"

Look through these threads. You shouldn't have to under-inflate your tires to get an acceptable ride. I run 25 to 28 lbs.

Post a pic of your current suspension so we can see your set up.

Using sandbags to correct a bad suspension? I'm not sure I like that idea!

Either your stock springs are wheezed or someone bought el-cheapo junk springs.

It's gotta be your leaf springs, I had some Superlift Springs on my '66 CJ5, I was running 32"s and tried all kinds of tire pressures, loosened all shackle bolts to 35 ft/lbs, greased everything and even put on on some Rancho RS9000 set to the softest settings and the ride OFF ROAD was still unbearable. The ride was so rough a kidney belt was almost needed!

I'm running BDS springs on my YJ now with the BDS Shocks and the ride is much better than the old CJ with those crap lift springs. In the future I'm planning on swapping out the BDS shocks for some Bilstein 5100s for an even better ride.

Again, track bars will give you the buck board ride. Take both off and you will be happy.

It could be lots of things.. Main thing being its a YJ. Loosten and re torque your spring bolts to the proper ft/lb, could grease them while your at it, tire pressure is also a big thing. In my 33" goodyear mtr/k i have 19psi which was decided after many chalk tests, shocks i find dont play much part in ride on leafs

and Ditch the track bars, and sway bar like Pasinbuy said! they are both useless.
