Here's some info on my spring install today.

Current ride height to mark on the fender is 39". This is with the stock springs which have a stacked height of 1" (leaves are 5/16" thick approx).
The new springs which are rated as a 2" lift raised the truck over 3".These springs have a higher spring rate than stock and have a stacked height of around 1 1/4". (the leaves are 3/8 thick approx)

Much higher than I wanted ! If I kept these springs. I would need to replace all the shock because there's less that 1" left of extension, and I would have to replace the steering arm to prevent bump steer.

I've opted to re-arc the new springs and take out 1 1/2", and hopefully end up with a height of around 41".
