Stiff ride

Hey guys! First post here.
I’ve got a 93 yj that I bought lifted 4 inches on 33s by the previous owner and I’ve owned it for a little over a year now and I’ve removed front and rear track bars and my sway bars. The ride is still stiffer than hell. I’ve rode in other yjs and a handful of cjs and they were not this rough. Is it just a low quality lift and should I switch it out or am I missing something?

Well not knowing what you have we can't say what the problem(s) is/are...

Shocks and springs are the suspects.... also your shackles could be binding...

Fwiw I have rubicon express extreme duty springs w +1 shackles and damn if I can remember what shocks on my yj w 33 10.50 km2's and it rides better than a stock tj

I don’t know what brand the lift is but seeing what kind of shape the jeep was in when I bought it, I can only imagine that it’s as cheap as you could go. If my shackles are binding up what could I do to fix that? Or should I start shopping for a new lift?

I have a similar problem. I haven't checked the torque on the shackles and spring mounts yet, but I have a feeling I'm going to end up with a new lift before the end of this year. Not only for the ride, but I doubt I get as much flex as I should be getting. And like you, I'm quite certain the PO cheaped out as much as possible.

Your shackle bolts could be too tight, causing the binding Gottagofast mentioned. Some people think tighter is better, and that's not the case here. The shackles need to be able to move for the leaf springs to flex properly.

Hopefully I'll get a chance to address mine this weekend. If it helps, I'll post back up here.

Noooo I don't buy into the shackle torque mumbo jumbo..... aftermarket poly bushings have steel tubes inside them... shackles tighten against the steel tube and it turns inside the bushing...

I'm talking about really long lift springs that may require 1" longer boomerang shackles to keep the springs or shackles from hitting the frame.....

If they're hitting that will seriously effect your ride.

The springs themselves on cheaper kits seem to be shorter than stock length springs. The lower bolt on your shackles should be ahead of the upper bolt (front shackles). On the rear, the lower bolt should be behind the upper bolt.
If your shackles are perpendicular or the lower bolt is behind the upper bolt (on the front) you need new springs. I suggest Rubicon Express or Old Man Emu, with a stronger preference for the RE kit. OME springs require their proprietary bushings and their kit is more expensive.

Let us know what you find.

Good Luck, L.M.

X2 I can't say enough good about my re 4.5's
MAKE SURE you get the extreme duty.. they should be ashamed to sell their standard duty 4" springs....

Back off the tension on all of the shackle bolts and the spring anchor point on the other end. Not sloppy loose, just take the pressure off. Drive it around the block a couple of times. Now tighten all the fasteners until there is no slack in the bolts. I know there is a torque spec but, the suspension pivot points must be able to move( flex ) or it's going to ride like a buckboard.
I run one of the most maligned suspensions in Jeepdom( RC 2.5 ) and have no issues with ride quality.
You can find my review here. Post #174

Didn't feel like typing this again. Copied from another thread.

Also, check that the bolts are still centered in the bushings.
