NKHammer I have 17/59 on my JKU (4dr sport unlimited). I upgraded to King resi shocks on all four ($1500) huge difference on and off road.

It's the last two numbers (not letters) that matter.

ram75 How do you read the label on the sticker on the springs? Mine read as follows, Front:52126314AC Rear:68004256AA Then each has a split number using the whole number-Example 5212 6314AC Same amount of characters front and rear used in the split. Split number same as whole number so I know this doesn't matter. Does it help the blind monkey some how?

The Tj springs are labeled differently. I don't know if they used such a large choice of spring rates like the Jk. You guys could just have a one size fits all spring. I do think the rubicon might have a stiffer spring stock unlike the Jk where it doesn't matter.

Ex- 2.5 lift

Somebody with 14/56 would see 3" + =73" total
Somebody with 19/60's would only see say 2" but still end up at 73" total because they were taller to start.

Understood ?
Yep, thanks for explaining it.

When I say "spring rate," I mean the change that occurs from a part number standpoint--front coils are available from around 12 to 19, and rears are available from around 52 to 60. You might be using it from some sort of mechanical engineering viewpoint, where it's a function of load and length and so on.

Used the way I intend, higher "spring rate" absolutely lifts the jeep. This is especially true on 2 doors, which (obviously) weigh less and are generally equipped from the factory with "spring rates" at the lower end.

Taking an otherwise stock 2 door from 14/55 to 19/60 generates about 2" of lift. Indeed, stood side-by-side without any load, the 19/60s will by considerably taller.

So what I was driving at with my prior post was that whether somebody "gains" more out of higher numbered springs or superior shocks really depends on what's important to them: If they want greater height or greater ride comfort/handling.
As an engineer I also realize that often the only thing that counts is what people that have experience know. I was just making an obtuse enginerdy comment on spring rates. I can't help it, promise...

JIMBOX Ride quality is purely independant , as I said earlier-

My Rubi weighs inexcess of 5200 lbs and with the 19/60 combo and RS9000XL shocks--in their stiffer setting and the ride is non-bouncing/non-leaning and "SOLID"/w abrupt speed bump action-

daggo66 I would think so if you left the puck in. I have the 19's in front and 60's in the rear and my Jeep looks level to me.

2" is quite a difference,. Wouldn't this change make the front end higher than the rear, if say you already had a leveling kit?

My Sport has 14/56, pretty happy with the ride currently.

No doubt that better shocks to go with whatever your current coils are will provide superior dampening, so they will be a "gain" presuming you don't like a bouncy ride. But you won't get any height. Higher rated coils will lift the jeep higher and provide a stiffer ride. Whether that's a "gain" (or an "upgrade" or "better"), is subjective.

Though it seems Wrangler makes all their spring lengths the same, technically a higher spring rate does not mean a higher ride height. The two are independent of each other and dependent on the unloaded spring height & rate (load also, but lets assume that is the same for each spring)

That said, you will get a small increase in height since Jeep makes their springs this way.

When I said "gain" I meant that for the money, shocks provide more change than springs will in the ride quality/handling department. I guess that change can go in the good or bad direction.

A ""gain"--"Better" ride to a 19 yr or "wife" is gonna be judged by "ONE" thats an impossible description--

It's like a guy says--I wanna raise my jeep 4"/35" tires and keep the ride same as "STOCK"--

It's a jungle out there and there aren't simple answers !

You and kjeeper (who has a 2007) are the only two I've heard of first hand. By contrast, I know a number of Rubi owners have chimed in to the various 19/60 coil threads and mentioned they don't have 19/60s on their Rubis. Anecdotal I know, but it all supports my DRUNK MONKEY theory!!

IMHO, I would start with quality shocks, OEM or aftermarket. This is where you will see 75% of your "gains".

rics1997 if you get them cheap enough. Really though, go to the vendor section and look at the ZONE thread. The zone shocks are dirt cheap and though they may only last about 80% as long as better shocks they cost less then 1/2. Last I checked they were in the mid to upper $30 range per shock and a good upgrade for non rubi's. The only thing about RUbi take off is you don't know what they have gone through. Blistens are great shocks but will cost in the $80 range and Fox (better shocks) are $100 each.

Crush2012 Would it be worth it to swap out Rubicon shocks into my Sport?

Great info. Thanks rics. I think I'll save myself the time and effort and give mopar a call for the 19/60's. Is it worth it to get HD shocks while I'm at it or are the stock shocks adequate? I plan on loading her down pretty good with towing/cargo.
