OME, Old Man Emu, what spring rate?

I am on the edge on what rear OME spring rate to purchase for my 2002 wrangler with both hard and soft tops. I rarely carry and gear and do live near some very poor paved roads. I am afraid the HD rears will be too stiff for a daily driver when I use the soft top and no cargo but at the same time do not want to bottom out with some rear passengers or gear. 95% of the time it will be empty with driver only. Any advise or experience to help me make the decision? I will be purchasing the complete kit (springs and shocks).

I'm about to do the same and have been advised to get the heavy duty springs. All I have is a hard top though, no soft top yet.

It's not really about the gear in the Jeep. Those spring rates are for CONSTANT loads. They're refering to winchs, bumpers, tire carriers, roof racks, armor, hemi engine, etc. etc. If your TJ doesn't have those things, go with the light/no load springs.

Put another way, the question for you is, "How much EXTRA weight is bolted/welded on to my TJ? And, relatedly, how much extra weight do I intend to bolt/weld on to my TJ in the near future?"

I've heard a number of times that folks have gotten the HD springs "just because" and been miserable.

Good point. That must be why I was advised of the HD springs,cause of what I plan on doing with my build.

they also have a medium rate spring.

personally, i would be going for the HD springs. 9x out of 10 we end up adding way more bolt-on stuff than originally planned. your ride quality will not suffer from the HD springs.

I agree with the adding more angle.

However, I'm not sure about the ride quality issue. I don't have OME springs, so I can't personally speak for their ride quality. But it seems to me that if ride quality wasn't impacted by using HD springs even when you don't have the recommended extra weight, then OME wouldn't bother making anything other than HD springs. They make different grades of spring for a reason.

I'm looking at going to OME coils too and will probably go HD. But that's because the armor, bumpers, and winch that will eventually complete my build will bring me within the recommended weight for HD coils.

I'd select the weight that actually describes what you intend to do with your Jeep.

The light duty and medium duty rears are the same spring, OME #941, HD is #942. I will not have all the armour, etc. but do have an aftermarket dual tube bumper (not very heavy) and a 33" spare. I would rather sacrifice a bit of ready quality and go with the HD springs if I will bottom out with 2 rear passengers like I have read on a few forums. I was hoping someone had experience with this but it is hard for me to believe that OME would design a light/medium spring that can not support a couple passengers or some gear in the rear. I will be using HD front due to the 6cyl and front bumper weight.

It seems like opinions are dead split between people saying that the HD is too stiff empty and people saying HD rides great empty or loaded.

I had an idea to get the rear HD and tune the pre-load by filling the rear bumper tubes with sand but I would rather not haul around the xtra weight.

I had the HD's at one point and ditched them because it was harsh and almost bouncing on the trails! I never tried other shocks when I had them, but I would imagine that didn't help things as the OME shocks are gas charged. The springs I have in the rear right now are rated at 10 lbs less than the heavy duty OME's and they provide a better ride but they are still too high! I had that same problem with the OME HD's as well. The only time I would get the HD's is if you run a hard top and/or have heavy passengers. On the other hand, if you feel you MAY have too much load for the standard duty coils then maybe OME isn't right for you. I won't spend the money for them anymore I know that. There are lots of other brands out there that don't cost as much and ride just as well (which is heavily dependent on the shock as well - not just the springs).

I bought my '97 with OME HD springs already installed so have never experienced stock Jeep suspension, but wouldn't change it for anything. Passengers are always praising the ride quality.

I am Running a Ranhco 2.5" lift. I got the one for Hard Tops since that was what I had on the Jeep at the time. Now that I run the Soft top in the summer it rides a bit higher in back. I also run the Rancho 5000's which a lot of people say are too stiff but that I really like. Nothing like the old pipe trucks I used to drive or the 77 Power Wagon with 6" Leaf spring lift and bad foam in the seats. I always go with the stiffer springs, not really going to cram too many people in the back anyway and also no sag when I put the hardtop back on.

I use the HD and I love it. It's a little hard but no problem for me and after some added steel it will be perfect. Wouldn't change them for anything else...

Yes, I have a dual top TJ. Stock front bumper, Aftermarket rear bumper/tire carrier.

I can get you the actual coil numbers once I get home and can look at the receipt.

Forgot to look at the receipt while I was at home. I just checked the actual coils, and the front ones say OME 933 and the rears say OME 942X. I'll double check the receipt when I get back home, because I know Dirk wrote it all out.

Okay, so apparently I have the HD coils. My front coils are part# OME2933 and my rear coils are part# OME2942. Links below take you to Rokmen's website. I bought my kit complete from Dirk at DPG Off-Road.

its going to depend on the accessories & weight of your jeep vs the spring rate and spring length you choose. thats the great thing about OME...you can taylor the springs to the needs of your jeep. you can do the math and calculate the ride height you'd like....then pick the appropriate spring.
