New RC 2.5 Springs Installed
I have had the Rough Country 2.5 progressive springs on since September 2009 and tracked the measurements since day one. You can see the data here:

Last night I finally got a round to installing the new front and rear linear springs that I received after a phone call to Ben Richardson at Rough Country. Ben confirmed that both the front and rear were linear.
As for the measurements, I took them from the ground to the bottom of the stock fender flares and another measurement, inside the (##), from the bottom of the dust cap on the wheel to the bottom of the fender flares.
March 14, 2009 with 1/2 tank of gas.
Before the new springs:
Drivers side
Ft - 38 1/2 (24 1/4)
Rr - 29 1/16 (23 1/2)
Pass Side
Ft - 38 1/4 (24)
Rr - 28 3/4 (23 1/4)
After the new springs:
Drivers side
Ft - 39 (24 3/4)
Rr - 29 7/8 (24 1/2)
Pass Side
Ft - 38 3/4 (24 1/2)
Rr - 29 1/2 (24 1/4)
I have an aftermarket bumper that is responsible for 1/2" of sag on the front springs. I have only driven it about 3 miles to make sure that everything was tight. I will post my thoughts on the ride later this week.
