Get a shock that has a compressed length slightly shorter. For street driven dropped vehicles I have found the extended length does not really matter much. In fact I have seen problems where "drop shocks" were installed and it made the ride bad because of limiting down travel. Topping out the shocks, not allowing suspension to follow the road. One thing I think is often overlooked by many is that a shock mounted at an angle is not moving 1 to 1 with the suspension.

I had issues w/my '90 single-cab swb. The rear was dropped w/a flip kit, shackles, & lower shock extension brackets. The rears tires cupped severely in less than a year. I looked into the lengths & found the shock basically couldn't compress (angle plus shock length). I swapped the stock replacement length shocks for some G-body shocks (slightly shorter & similar mounting arrangement). Put fresh tires on & no more cupping issues.
