What is Level? 1987 Suburban

[rideair]

I know it sounds like a crazy question, and maybe I'm just a little to anal, "but" (pardon the pun), what is consider "level" when dealing with a 1987 Suburban?

Thought my 1987 looked like it had a little of the rear squat. When measuring the height on the wheel well lips, the rear was lower than front by about 1". Front 36" 3/4, Rear 35" 3/4 inches.

So I thought the fix would be:

Purchased the ORD Zero-rate 1' spring kit, it was installed, great product, but now, the Suburban looks high in the rear, not level even though the wheel well lips are 100% the same! Front 36" 3/4, Rear 36" 3/4 inches.

Now, if you measure along the bottom of the rocker panels under the doors, front area of the front door is 17" 3/4 inches, rear area of the rear door is 19" 1/4 inches.

Even the body break line that runs down the side, 42" front, 43 1/4 rear.

So, what is considered a "Level" Suburban? Wheel Wells, Body Line, Bottom of Rockers, Bumpers, etc....

In the words of the guy in Dirty Harry, "I got's to know"

Enjoy,
