Stock Coil Springs - Driver vs. Passenger

I apologize if this is easily found somewhere on the forum, i did a search but couldnt find anything. I have an extra set of fully assembled shocks and springs for the front of my 2006. I plan to disassemble these, install my 5100s, and then reassemble so that when i take my truck to the shop, they are basically changing out my own "quick strut" assembly. i know that the stock coils are specific driver to passenger side. Which side has the longer coil spring? I'm assuming its the driver's side to make up for the extra weight of the battery, fuel tank, driver, etc.., but i'm not 100% certain. I want to make sure i mark the new assembly correctly for the shop when they do the install for me.

 

hmmm, i measured one about an inch longer than the other. i took this measurement assembled. i got these from a member on here, so i have no idea which went where originally.
