I ended up getting about 4" of lift on the front and 4.5" in the rear. It should come down a bit after an alignment because it has some positive camber up front, and the rear springs will settle. Also, it came at a perfect time because I found that both of my rear shocks were toast once I got them off the truck.
I took before and after measurements from the center of the hub to the fender, and from ground to fender on both the front and rear... these measurements are lift only, no tires, and we're taken immediately following the install so they do not reflect any settling in the new springs.
FRONT:
Driver's Side, Before: Ground to fender = 33", center of hub to fender = 18 7/8"
Driver's Side, After: Ground to fender = 37", center of hub to fender = ???, forgot to measure
Passenger's Side, Before: Ground to fender = 33.5", center of hub to fender = 19 1/8"
Passenger's Side, After: Ground to fender = 37 1/8", center of hub to fender = ???, forgot to measure
Based on these measurements, the front gained about 4 inches of lift. It also appears that the factory coil on the driver's side had sagged quite a bit. Both front shocks were also going bad.
REAR:
Driver's Side, Before: Ground to fender = 34 3/8", center of hub to fender = 20.25"
Driver's Side, After: Ground to fender = 38 7/8", center of hub to fender = 24.5"
Passenger's Side, Before: Ground to fender = 34 3/8", center of hub to fender = 20.5"
Passenger's Side, After: Ground to fender = 38 7/8", center of hub to fender = 24.5"
Based on these measurements, the rear gained about 4.5 inches of lift. These measurements were taken without the spare tire mounted under the vehicle.
It was slightly raked before, but picked up an additional 1/2" of front to back rake from the lift. The amount of rake didn't end up where I thought it would be, and that's a good thing. I'll take more measurements down the road to see how the springs settle out.
EDIT 2/19/11:
I just measured it after installing the sliders, these measurements are with 285/75r16 GY Wrangler Duratracs installed as well (previous measurements were on 265/70r16's)... Ground to Fender........
Front Driver/Pass. sides: 38"
Rear Driver/Pass. sides: 40"
