you use a ramp/bump/pothole to cycle the suspension everyday you ride on the road.
problem is, you need a way to simulate that in your garage. You have to make the frame and axle come together somehow...slowly, in a controlled manner.
And since the springs hold the frame off the axle, the easiest thing to do is remove the springs. Support the frame, drop the springs out, then use a floor jack (or a lift of some sort) to push the axle up to full bump and full flex. You also check tire clearances, full droop, brake line length, etc at the same time.
If you're looking at flex on an RTI ramp, hill or something, you're not even getting half the story.
