18.25 hub to fender in front, have not installed front yet, only rear just today.

Rear was I think 19.5 ish, now 20.25

OME 731, Bilstein 5125 33-185552

No isolators besides the stock

If by extra you mean weight, the car is stock and empty besides a fishing pole or three.

This is something I found, but its front, and its KJ, but shouldn't the rear springs also be blatantly taller?

Well, finally found tech specs, 2731 is only 300mm tall (11.8 inches) which is what my tape measure shows. How can this be when the oem ones are 11.3ish? Is the KK limited a higher spring rate thus a lower amount of new ride height compared to other oem liberty springs?

Lift springs have a higher compression rate than stock springs so they have less squish. This could lead to different lift heights from springs that have similar unloaded lengths. But I don’t know why you didn’t get the height you expected. Maybe they sent the wrong springs?

You can have 4 different springs that are the same height unloaded
but when on a vehicle give 4 different heights
it all come down to the diameter of the wire used, the compression rating built into each spring
we have ran into this hundreds of times when people start measuring things without knowing exactly what they are measuring
in the case of different springs, how each is rated , etc
all OE springs are basically the same each rated at 310 lb for the fronts which by the way to low, should of been 340-345 lb

52109894AE is the stock spring I had on there. Here is the tech sheet. Says 2731 is 300mm (11.8in) and spring rate is 280 while stock is 200, according to this chart.

Maybe someone who knows what they are talking about can chime in, preferably without elitist sarcasm. Not once did I ask for a lesson on how springs work, I asked why the 731 is giving an inch or less of lift.

I swear, internet tough guys love to belittle people in every answer, little jabs, don't know what they are talking about, waste people's time not answering the question, nitpicking over **** that isn't even that relevant, to what, boost your ego? If you don't have legit troubleshooting on the topic, kindly take that childish **** elsewhere. Not talking about Howard, who I thank for the attempted help.

No one is asking about front springs. No one is asking about 4 different springs. I am asking about 2 specific springs. But thank you for chiming in on people who don't know what they are measuring.

Like what the actual **** is the point of this message? Talking down sarcastically over a 1/4 inch in the FRONT when trying to find a whole TWO inches in the back. What is wrong with you? Or should I put more question marks to show superiority ???

Seriously. It doesn't matter what I measured it to be, it's the differential measurement that matters. I can measure it 30 in instead of the 18 it is supposed to be and with the new springs it should read 32 by the same measurement. Grow up. You want to talk down to me over a quarter inch? Quarter inch can be a warped fender, uneven pavement, quarter inch is nothing.
