It'd do what stites-xk did... one full coil off and no preload spacer.

Also, my reason for longer shocks (28" for 2-3" lifts and 31" for superlift+) is to maximize rear end travel. A few minor mods usually need to be done in addition to take full advantage of the longer shocks, but they're minor. Check brake and sensor lines at full drop, gas tank skid clearance, etc. And check for tire clearance under full compression; add longer bump stops if needed.
