Need to determine if my 07 silverado classic already has a leveling kit installed.

I recently bought an 07 Silverado 1500 classic. And have been wanting to raise it a couple inches. A couple friends suggested a leveling kit. Well looking at the truck it appeared very level so measuring from the ground through the center of wheels to the fender well was 37” even on all 4.  The rear lift blocks measure 2 1/4”.  Tires are 265/70 17  My question is does the truck already have a leveling kit or are they pretty level as stock.?

Take a look at the torsion bar keys. Do you have a picture looking at the front a-arms and driveshafts?

Looks like the keys might be cranked up a hair. An alignment shop can tell you exactly how much.
