Replacing oem coils with a spacer, or doing a 2" lift with aftermarket kit??

My LJ is ten years old with 25k miles on it and has pretty much sat in a garage for most of that time. I'm not sure if it's the shocks, springs or both, but this thing rocks violently from side to side every time i hit some bumps or potholes on city streets at low speed (at highway speeds it's decent).

I'm looking to get the best possible street/highway ride with no interest in offroading or rock crawling.From all my research (scouring jeep message boards mostly, my GF is ready to break up with me over this, btw) i think a 2" lift would be the best idea (partially because I want to add 31" or 32" tires).

Could my shocks and or springs have gone bad simply by sitting in the garage all that time? It feels like one or both are shot, and I'm only too happy to replace both regardless, I just want to make the best decision that suits my street needs.

Any advice would be greatly appreciated.

Thanks!

When you mean rocks side to side, do you means body roll laterally or the steering wheel turns causing the jeep to turn? Or does the shaking cease when you come to a complete stop because it could be a lot worse than springs/shocks? Shocks are for sudden, heavy impacts and springs give a comfy ride. I don't know what would cause your problem but a 2" spring lift would most likely solve them.

The body rocks side to side, the steering doesn't move. WHen The jeep stops, everything else stops, it's just during the bump / pothole that the problem occurs.

Sounds like it could just be the shocks. But if you wanted to put in a small lift to go with a slightly larger tire, most suspension lift kits will include new shocks and springs. For a great riding 2.5 inch lift, check out OME (Old Man Emu) For a 3 inch lift that's a little bit less money, check out Zone. Still a very good ride..I just put this one in my Jeep.

This kind of confuses me. The bump/hole initiates the problem but does the shaking continue until a complete stop? Most likely your shocks need replacing and would come in kits that reb6672 suggested.

No it stops after the shake response from the bump. It settles pretty quickly regardless if i stop or not.

But before you buy that lift and bigger tires..check the clearance in your garage. Mine JUST makes it with the 3inch lift and my small tires. When I go bigger tires..I'm going to loose the garage spot I have to go and buy one of those portable canopy garages now.

Yeah that's not going to be a problem since I pay for a garage in nyc. It's only the price of the parking that's the issue.

Right well, this brings us full circle to my initial question. I want to do a 2" lift, (no more than that), but even 2" lifts end up being higher because they are rated for Jeeps which carry extra bumper weight, winches, etc.

So, I'm thinking to either go with OEM (not OME) coils, and then doing a BB, or the better case would be to find a true 2" coil (preferably progressive) which I could use here. I'm planning on adding Bilstein 5100's regardless.

Any advice here on how to pull off this 2" street use only lift?

it sounds like you're off to a good start. I'm going to point you back to OME now haha. Here's a link to their 1.75 inch budget boost. Old Man Emu TJ/LJ Econo-Kit | dpgoffroad.com The shocks that come with that are some of the best for a TJ. I actually want to say they are comparable, if not better than Bilstein 5100's. Reviews I've read say the ride is the same, but the OME's tend to last longer. It includes the shocks, coil spacers for the small amount of lift and rear bump stop extensions.

That's great (and I appreciate the advice) but it still doesn't solve my ten year old coils that probably should be replaced issue. Do you recommend I go with stock (OEM, not OME) coils? If so , where would I ever get those, mopar? And, at that point, wouldn't it be just as good if not a better idea to simply forgo the spacers altogether, and simply go with new 2" coils?

I really don't think the coils would need to be replaced. Going to OEM coils again will probably not do anything at all. Maybe a slight..very slight lift in ride height. The ride quality is mostly in the shocks.

BDS is also a very good quality lift..they make a 2 inch lift that includes new coils and shocks. I don't know much about it other than I don't hear any complaints about BDS at all.

2 inches of lift, you MIGHT be able to squeeze 32 inch tires under the Jeep but it would be better suited for just 31's.

You said you were looking for the best possible ride for your Jeep. That's why I keep pointing you towards Old Man Emu with their springs and not towards a budget boost/spacers. BB aka coil spacers will get the job done to put in bigger tires and gain ride height. but IMO, the right way to do it with the best ride quality is with aftermarket springs. Hands down, that's the best setup for the tire size you want to go too in that lift range.

If you ever want to take a ride over the river, I work right near Giants Stadium. I just put in a 3" lift. I know that's higher than what you're looking for, but you can get a feel for how the Jeep drives and feels with aftermarket springs/shocks. I'm sure the crappy roads here in the Meadowlands are comparable to what you're going to be dealing with in NYC

Gotcha and thank you. I might just go with that. The reasons I've been shying away from OME is:

1) While they say 2 1/2", my understanding is they will likely end up close to 3 1/2" (due to the fact that they are factoring in heavier bumpers and equipment to weigh them down some; I'm running fully stock). At that height, not only do I not like the aesthetics, but I will also be entering a new arena of needing more equipment to deal with the new angles (adjustable trackbars, control arms, and just more work and stuff to deal with and maintain.

2) I've been reading pretty consistently, that while OME makes a very high quality product, on the street, they ride a bit hard due to them being linear coils, as opposed to progressive ones. My understanding (and I'm very new at understanding any of this, so I will surely defer to almost anyone else in this forum) is the progressive coils will offer the best low end range, which is likely the range I will be in mostly in the city and highway. Linear coils seem to do better off road.

I really appreciate all the feedback, and I'm very interested in your thoughts on this. It's been difficult sifting through all the information, especially when so much of it is contradictory.

Thanks again.

They actually have different spring rates depending on what you want to do and the results you're looking for. Most on here will go with the heavy duty spring rate..I think those are the ones you've been reading about. They're the ones that will be a little stiffer to compensate for bumpers/winches and all the body armor.

I must have spend the past 2 months reading about different suspension systems and spring rates on here before I bought my lift. I plan on doing very light offroading, but I also drive an 80 mile round trip from Northern NJ (near the poconos) to about where Giants stadium is for work. Traffic here is a nightmare, and the roads are usually worse so I needed something that would give me a safe and better ride on the road. That was my main concern when I was shopping around.

I gotta admit, you're beginning to win me over. So you're running OME's now? On what size tire? Could I see a pic of your setup?

haha Now you're going to laugh. I'm running the Zone 3 inch lift. It was a VERY tough choice between the two for me. Zone vs OME. I wanted a little more height since I was thinking I was going to go to 33 inch tires. But now I've decided I only want to go to 32's. I'm currently just running the 30x9.5 tires now. Since I do alot of driving in it, I like having stock like power, use of my 5th gear and decent gas mileage. All of those will be gone with bigger tires if I don't regear the axles. That's in the future..but I don't really NEED to do it right now.
