How to soften ride??

Ok here is whats up. I installed a 4" Procomp lift about 2 months ago and of course i new the ride quality would change. The ride was definately ruff but i hoped that is would loosen up some after a couple thousand miles. The suspension is still very stiff. No matter where i am driving the whole jeep bounces up and down. When i installed the lift i ended up with some *EXTRA * washers, Im wondering if they were supposed to go between the shackle and the leaf spring instead of having the rubber on the leaf spring rub on the shackle the washer would,?? Another question is would getting a different style of shackle help soften the ride. I konw I cant have a luxury ride but anything would help!

I don't think there's that much difference btw rubber and poly, but new rubber pieces for the suspension and body will be the softest theoretically. Did you (lithium) grease the suspension when you assembled it? How tight did you make the shackles?

Tire pressure seems to make the biggest change to me, 24lbs rides a lot softer than 28lbs. I tend to feel that it wanders too much when that low, and slides too easily in the rain (forget about the snow), but if a soft ride is what you're after...

I took the smallest leaf out on my Trailmaster lift. Rides great and flexes like the expensive ones. Didn't lose that much lift either (the width of a leaf ). I'm sure it will weakin the springs some, but so far they've held up fine, without any sagging, and i've thrown a lot at them.

I also have new shocks...DT3000s, cheap and they ride fairly well.

I took the smallest (bottom) leaf out of my pro-crap stack hoping to soften the ride a little. It didn't seem to help much. I also lost about an inch of the lift by doing this. I finally gave up on it and replaced it. Greaseable shackles and main eye bolts can only help. Also make sure the shackle bolts are not over torqued. Are you still running with the sway bar and track bars? Removing them make a difference.

Never Buy Pro Comp Springs

You have a Pro-Comp lift...there is nothing you can do. Seriously. Nothing.

It is the stiffest spring there is. I made the mistake of replacing bent front springs with pro comps (I am embarrassed to admit it). It is awful. Pro comp has no business or excuse make springs that stiff.

You can air down to 20 and that will help some, but you are screwed. Sorry.

That is the very reason I renewed the following thread: http://jeepforum.com/forum/showthread.php?t=178834

I am getting rid of my pro comps for Rubicon Express.

For those who may read this, NEVER BUY PRO COMP SPRINGS FOR YOUR JEEP!

They will bust your spleen and knock the fillings out of your teeth on a smooth paved road.

Oh yeah..new shackles will make no difference...save your money.

I've got an RC lift, and man was it stiff. The instructions had the shackles torqued to something like 95FP. ugh. I loosened them to 35FB as recommended by some folks on the board and it helped signifigantly.

With those stiff leafs, you have a few options. I would first loosen the shackles like Richmond88yj recommended. Use nylocls or locktite on the nuts so they don't back out.

Next, I'd remove the front and rear trackbar. The rear is a nobrained but the front is more of a perferance. Well on softer springs. Since you've got those stiff springs, you won't need to stiffen the front end any more. Some people like to open up the spring clamps so the springs can work independantly when needed. Better shocks would help also. Those cheap ES3000's are really hard. You'll want to make sure you grease all of the bolts and bushings too.

Longer shackles may help but that will really depend on what the shackle angle is once it settles. Then you've also got to think about camber angles as well as pinion angles with those.

No matter how long his shackles are the springs still will not bend - they are too stiff. With my Pro Comp springs I tried long shackles and then switched to boomerang shackles. It made no difference. Save your money!

what your probably feelin is the back suspension kickin when you go over whatever, its gonna be more in the back than the front. if you go over speed bumps slow and concentrate you wil see what i mean. I would take out a leaf in the back, not the short 1`st one ,the second one. i`m basing this on the style leaf pack i had. I didnt lose any lift (thats how nasty it was) if you lose a inch or so make it up with a long shackle. this probably isnt the ideal thing but its workin with what ya got and you`ll probably be happy with the improvemnt.

Well as you've heard here... you bought the worst possible springs you could have. I do know that when I removed my track bars the ride improved on mine a bit. That said... I do love my OME lift cuz it rides nice!

I've had my 4" procomp in since the spring and it takes a while for them to soften. If your looking for a softer ride go with a street tire. I just put on my crappy 31 radial no name tires for winter and it rides smoother then BFG All terrians.
Especially on pot holes the tires can absord alot more impact.

I don't run a rear trac bar either

thanks everyone for the input. I am going to loosen up the shackle bolts because i remember torqing them down pretty good when installing the lift. I didnt get the procomp shocks so i think ill be fine i ended up getting SkyJacker shocks instead so anyways. As for being the worst lift made.... not to be rude or nothing but Im happy i have a jeep with lift and tires. I bought what i could afford and thats that. Thanks Y'all Yah a Tj would be nice someday!!

ive got the pro comp lift and its not that bad, its a little rough but has loosened up nicely after some off roading trips. no front sway bar is the way to go along with loosening up your shackle bolts. flex it out a bit too. as far as the spring clamps go, anyone have any more information on if that helps at all by loosening othem up?
