Very interesting----I thought I knew it all when it comes to suspensions. Both my trucks are gone right now--when they come back, I will look and also call my suspension buddy in CA. </div></BLOCKQUOTE>Well, I made one more phone call and here is how I understand it. It is actually a "supplemental spring," not "end spring" as I said earlier. It helps to make the whole front suspension more progressive but lessens the overall weight while doing so. Other technical terms are "micro cellular urethane" and "zero-weight spring." I guess, because it supposedly offers spring without the added weight from extra metal in heavier torsion bars.

Also, since the torsion bar is a "smaller" one, it offers a softer ride on the road. The torsion bars are "tuned" with the jounce bumpers to provide the smoothest ride, especially when the suspension compresses fully. Changing the bars or stops will change this "tuning" and make the ride different.

As I understand it, this is something commonly used in small cars. I don't really see how it was conceived that this was a good idea for an off-road vehicle. The physics involved with the H2's front end would seem to preclude using this design. And yes, some cars sit on the bumpers when they are at rest and some don't. Many are designed where the frame component is just barely touching the tip of the jounce bumper.

Go figure!
