I am unsure of my exact lift height. I measure 18 3/8" from the ground to the framerail next to the trans crossmember. I have the equivelent of 30" tires.

11"! Um, no. I guess around 5" but want to know for sure because im buying new springs to replace the ones I have and the spacers and want the correct length. Heres a pic.
To get the correct measurement, you cannot measure from the ground. There is too much variation in actual tire sizes and pressures that will affect the demension. Measure from the top of the axle tube to the bottom of the frame rail directly above the axle.
Quoted from NAXJA:
Checking Front Ride Height
Measure front ride height with the vehicle unloaded (no luggage or passengers) and with the fuel tank full.
Place the vehicle on a level surface and measure the veryical distance between the top of the axle tube (A) and the underside of the frame sill (B). Refer to Figure 1 for driver's side measurement and Figure 2 for passenger side measurement. Be sure each measurement is taken from the top of the tube and not from the axle or shift motor housings.
With Standard or Soft Ride Suspension, vertical distance should be 17 cm (6-3/4 inches) plus or minus 13 mm (1/2 inch). With Heavy Duty Suspension, vertical distance should be 20 cm (7-3/4 inches) plus or minus 13 mm (1/2 inch).
Checking Rear Ride Height
Measure rear ride height with the vehicle unloaded (no luggage or passengers) and with the fuel tank full.
Place the vehicle on a level surface and measure the vertical distance between the top of the axle tube (C) and the underside of the frame sill (D) inboard of the jounce bumper (E).
With Standard or Soft Ride Suspension, vertical distance should be 15 cm (6 inches) plus or minus 13 mm (1/2 inch). With Heavy Duty Suspension, vertical distance should be 18 cm (7 inches) plus or minus 13 mm (1/2 inch).
