Track Suspension

[Loren]

I'm glad someone grasped what I was saying... I really felt like I was rambling. I literally had an awful headache at that very moment and wasn't sure I was making sense at all!

The problem with using 2.5" ID springs in the stock location is that the way the rear axle assembly moves, the lower spring perch does not come up in a straight line. It's fairly level at rest (at stock ride height), but as the suspension compresses or droops, that lower perch takes an angle compared to the upper perch, this makes the spring want to bend. Small diameter springs don't like to do that. The larger diameter spring will help with that, as will the pigtailed end.

2.5" ID springs are available in any size and rate you can think of, and they're dirt cheap (relatively speaking), but I'm not sure they'd work well for this application, unfortunately.
