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...

If you can gain as much as 2 inches,. It got me wondering. What do suspension companies base their lifts on?

If I went from 14/56 to 18/60, would I have as much lift as if I bought a Skyjacker or Teraflex 2" lift?

No

You would get more lift but because you had less stock.
Essentially all end up the same ride height after lift install.

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.

Basically nothing.

I have a 03 sport and was trying to figure out what springs I have but the only tag I can find is on one of the front springs... 224000 miles has worn the others off. I see the numbers 129Ab and 71765 and a long one of 52088129AB. My question is what spring do I have on this Jeep...

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.

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?

Those are 14 and 56.

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