Stock Height of 1986 GMC K1500

[jmora78]

Hello, I'm trying to figure out how much lift the front of my truck has. It has 2" blocks in the rear and sits pretty level so I'm assuming 3-4" in the front. I was thinking that an easy way to determine the lift would be to measure the ground to fender distance and compare it to a stock value. Mine is sitting at 40-5/8" (front fender to ground). Is that the best way to go about it? If so, does anyone know what that stock value is? I'm trying to figure this out because I need to change out the shocks and want to make sure I get the right size. Any help/insight is appreciated.

 

Thanks!
