A really rough ride...

I've had my lift now for about a month...i have never ever had such a rough riding vehicle! Am i going insane? Is it because i have larger tires? Should my ride be this rough? Its a 4" ProComp lift with 33x12.50 tires...sure its great in town, but on the highway, i almost lost it hitting cracks/bumps in these LA roads Is there something i can do to improve the ride quality? It gets to the point where my cd player skips...mine NEVER skipped when i had the stock suspension...


Thanks in advance.

Cheers,
Reclaimer

It really shouldn't be that bad. As kits go a 4" is as far as you can go on a short arm kit. You will give up some drive ability, but not beat you up. You need to go over every thing for tight. The TB's and CA's are most likely the cause of driving issues.

That would be the first thing I would check. Also, as stated already, a 4" SA lift isn't going to ride great so that's probably part of it too.

Did you put the lift in yourself? Did you get an alignment after the lift was installed? If it is just the front end then that could be the problem. If it's the entire ride then try going over and tightening everything up.

Pro-Comp lifts are notoriously rough riding lifts, both in TJ's and YJ's. I know several people that have swapped out their Pro-Comp lifts because of the ride quality in their DD TJ's.

I had it professionally installed by someone in town, they did a good job on it, got it aligned too. I just got it out of their shop again for the 500 mile maintenence check, they said all was well.

I've had some buddies of mine, who own full-size Titans/Silverados tell me ProComp is the way to go...i guess from expierence their advice only goes for full-size trucks!

ProComp's suspension lift kits come with one of the stiffest riding shocks around, the ProComp ES-3000. Your stiff ride can certainly be primarily attributed to the ES-3000 shocks, with possibly your tires having been overinflated too. Remember your air pressure is not supposed to be what is molded onto the sidewall, that is only its max allowable pressure. Radial 33" tires should be no higher than around 28 psi for a Wrangler. No worries about the springs, ProComp's coil springs are actually very good quality and will give a very good ride when paired with the right shocks.

If you ended up replacing your shocks, a very good riding inexpensive shock is the Skyjacker Hydro (not their Nitro!!). If a little more $$$ isn't a problem, Old Man Emu's shocks have a very good ride, as do Rubicon Express Monotube (not twin tube!) shocks.

I've been running with Rubicon Express - monotube shocks and I really can't say enough about them. They are awesome....

If the tires are not grossly overinflated, yes replacing the shocks with something like what was recommended will make a night and day improvement in your ride quality.

Here's a few shocks commonly listed for Wranglers in websites like Quadratec to AVOID because of their stiff ride when installed on a vehicle with the weight of a Wrangler: Rancho R5000, Skyjacker Nitro, Rubicon Express twin-tube, Rancho RSX, ProComp ES-3000, ProComp ES-9000.

i have the skyjacker hydros, and love them. sometimes they are almost too soft and can get bouncy. but they are very smooth, and articulate extremely well off road.

found these too @ quadratec

Old Man Emu N66L - Old Man Emu Front Nitrocharger Shock Absorber for 97-06 Jeep® Wrangler TJ & Unlimited with 3.5-5" Lift - Quadratec

the OME shocks seem like a sound investment even though they cost 82.00 compared to the skyjacker 39.00 shocks...it comes out to about 321.00 for all the shocks...this even seems like something i can do myself! just basically replace whats there allready.

I can vouch for the less than appealing ride of the RE twin-tubes even with leaf springs!

Yep, you don't even need to remove the wheels or jack up the vehicle to do this.

Good choice, and yes they are pricey but...Words to live by....."You get what you pay for". You want to go out and buy a lift for $300 that is exactly what you'll get a $300 POS that you will constantly have to change parts or upgrade......IMO that is...

Seems the problem is narrowed down but I'll throw out the fact that going from military leaf springs to parabolic leafs on my buddy's series was compromised due to pro comp shocks, they ruined that lift kit.

So new set of shocks will do you good.

x2 on the crappiness of ES3000s. I should have listened to Jerry when I got my PC 2" lift and upgraded the shock. But noooo - I went the cheap route. If you want to stay with Pro Comp I hear the MX 6 monos are pretty good and they are 6-way adjustable.

Well, i checked my PSI on all my tires...and they were set @ 40 for each tire! i didn't have alot of time on my hands to i decreased each of them to 35psi. i had to run pick up some supper for the family and i did notice a small difference in the ride, ill try it like this for a while then i may remove some more air.
