Rob,
You are correct. It equates to about a 4.5in drop in the front.
The HQ single adjustable, smooth body shock comes in the StreetGrip kit. The shock in this kit was spec'd out for the mounting height this kit provides. We do have multiple stroke lengths available in the HQ line up.
If you can get me a measurement from the center of your top mount to the center of your bottom mount, I can figure out exactly what shock length you need.
Give me a shout whenever you get some measurements and we can get you squared away.
