with front 4x4 after market lift springs out of a truck what a good way to see how much lift they really are?? i bought used ones and am unsure

I am going through the same thing right now. Like Irish-Alley said the only way that worked for  me was to put them in. I had a pair of Ranchos and a pair of Rough Country's that looked identical side by side but the rough country's sat about 1.25" inches taller than the Ranchos when installed in the truck.

ok my friend just gave me a awesome idea.... jack up a truck and put them under a tire for weight and then measure them... its so simple

I thought of that also. The only problem is when you come up with a measurement what will you compare that number to? Unless you do the same test with the stock spring all you will know is how much the new springs compress under a load.
I found out the hard way that comparing them side by side didn't work because of the different spring rates.

geez... . I REALLY WOULD WANT TO EVEN TRY THAT STUNT OF YOUR ...OR BE NEAR IT .!!!!!

THAT TIRE SPINS ALITTLE BIT AND THAT COMPRESSED SPRING UNDER THE TIRE WILL COME FLYING OUR WITH GREAT FORCE!!!...THINK ABOUT IT  OR BUY YOURSELF SOME LIFE INSURANCE BEFORE GOING OUTSIDE TO MEASURE THEM THIS WAY!!
