Yes they are, I believe there are only one set stiffer, 19's and 60's.

From what I can tell the "stiffest" springs available are 19 (front) and 60 (rear). What are you currently running?

I am running the Teraflex 2.5" coil and shock lift, but picked these up on Ebay for a good price.
I am not sure what I am going to do with them, but want to keep them around in case I downgrade the lift.

Hello!
I read through most pages in this thread, but have to admit, that I scrolled thru some, just looking for numbers.

So, here's what I have found (JK was second hand, but mostly stock):

1 - CRD Unlimited Sport 4-door
2 - Hard Top only
3.1 - Front Left: 5212 6515AB yellow tag
3.2 - Front Right: 5212 6516AB red tag
4.1 - Rear Right: 6800 4459AA lime green tag
4.2 - Rear Left: 6800 4458AA (no colour tag, maybe white or black)
5 - Black, gas charged: 5212 6751AC
6 - Fourth Digit in VIN: G (2585kg/5700lbs)
7 - 2009 (Built: 8-08)

Don't know if there was a factory tow package specified, but it has a Mopar/Brink hitch fitted with a 3500kg/7716lbs rating, and 140kg/308lbs tongue weight.

What I noticed in this thread:

front springs: all posted so far have 63 in the part number, only mine has a 65 - that may be Diesel related, but maybe not!?!?!?
Some German off-road publication mentioned once, that the Diesel engine itself is about 90kg heavier than the 3.8 gas engine ... I leave those 90kg unconfirmed! And then there's the big OEM Optima yellow top on the right side and 85 Liters/22.5 US-Gallons of diesel in the tank.

rear springs: so far all 2-doors had a spring part number containing 42, all 4-doors have 44 in the part number, except one unlimited owner, who posted a 42 part number.

Interesting thread. If anybody can help. I am trying to locate a credible source of maximum gross weight for a 2007 rubicon 4door I need it to be over 2500kg or around 5700lb.

Since Jeep.com lists the current model year @ 2237kg, I think you're going to be disappointed.
