best way to soften up ride??

I have a 93 yj 4.0 and it has a 3.5 inch superlift with the shocks included. I was looking for a way to soften up the ride. It is as stiff as riding on steel beams. I know the better lifts have better rides, but what are some ways other than loosening up bolts that I can soften up the ride some????

Depending on how long the lift kit has been on, I would recommend taking it to a suspension specialty shop and having them re-arch the spring. I did that to my rear srings in my YJ and noticed a tremendous difference in the ride quality. My springs are the originals and I had one of my coworkers arch them up 2 inches and the added pep of the the re-arching worked wonders. Good luck.

I wouldn't recomment re-arching the springs just yet. Take off your track bars. Start with the rear and see how you like it. If you want it to soften up more, take off the front. Some people say the get more body roll/lean when they take off both, but most say it doesn't bother them enough to put it back on. Mine was a little stiff, so I removed the rear track bar. It made a world of difference. I didn't even bother removing the front. Let us know how it turns out!

Losing the track and sway bars will only help. Also make sure the shackles are not torqued to 100 ft-lbs. I don't know about your shocks, but quality shocks can make a big difference as well. Greasables all around (shackles & maineyes) made a noticable difference when I installed them. Be glad you don't have Pro-Comp. I've had both Superlift and Pro-Comp and the SL was way softer.

you could pull the bottom leaf out of each pack, that'll soften it up a bit.

Switch to round springs.

What is your tire pressure? I aired mine to 25lbs from 35 and loosened the shackle bolts and replaced the nuts with nylocks so they don't rattle off. World of difference.

I don't know how old your springs are, but if you just put them on then they will probably soften up a little as you break them in. Tire pressure does wonders also. You can remove the bottom spring and it will be a world of difference. My brother did that on his CJ 5 with a Pro Comp lift and it improved it alot but his springs started sagging really early in the game too so I would try everything else before I did that.

If you don't already have them.. Get some greasable shackles and torque the bolts to 40 ft/lbs. Doing that made a huge difference in my ride quality.

Well, the springs are still relatively new, so they are still stiff, but the PO had them all put on. I have loosened the shackles slightly and used a little lithium grease not that it did anything, I have my tires set to around 28 lbs of pressure, and its a superlift 3.5 lift. The rear sway bar was gone when I got it, and the track bar is too. I'm probably going to take the front sway bar off just to see how it drives, and then if its undrivable, throw on quick disconnects or make my own.

In this order:

1. Air down to 25, or even 20.

2. Make sure the shackles are not on too tight. If they are your ride will be very harsh.

3. Try different shocks.

After those three things are done, the only thing left would be to replace the springs with something less stiff.

I do not believe the track bar or sway bar are going to make your ride stiff. They simply control stability, so save your time working on disconnects.

I had pro comp for a while. They sucked. Ultimately I had to buy new springs to fix my ride.

yeah, the shocks that are on it are no name and I would definitely say that they came with the kit or the po before me scrimped pennies and just put cheap shocks after he bought the kit. I would really like to change out to a good shock, but what would you guys recommend for a 3.5" superlift riding with bfg mt 32x11.50 tires?? I have looked at the 5150 more because I liked the looks, but hows performance on those things? I used to be a rancho fan, but they ride like a rock as well. What would be the softest riding usable shock out there for a reasonable price?

Trac bars link your axle to the frame....you better believe that they will stiffen the ride. Bumps are more harsh as well.

I removed my rear trac bar and my sway bar....world of difference...front trac bar will be next.

A track bar will only stiffen the ride if they are at a large angle. When at such angle the rise and fall will cause a push to the frame, but usually will result in a twitch also (like a slight side to side bump) whereas the push is not directly up and down. It is kind of the same effect on ride as bump steer is to steering. If the track bars are on anything near a parrallel plane (ideal set up) then there will be very little if any effect on ride stiffness.

While this is technically true, my ride softened a lot after the rear trac bar was removed.
