Hum…truck appears almost level even with the longer shackles? Is that correct? Or is the picture/driveway sloped some?

Looks like you installed the military/double wrap on the shackle end rather than front hanger like normal. Wonder if that makes a height difference and maybe why the stock shackles did'nt work? Should work either way with the longer shackles but stock the springs roll under on the shackle & over on the front hanger which supports the weight better. The military wrap adds to that and gives some more insurance if the main breaks.
