Jeff - the references to the myriad of myth re-posts are not reviews, merely a re-hash of the myths themselves...mostly threads like this one, that you're reading in fact.

Here's a quick google for reviews:

Yeah - ALL suspensions eventually reach their limit of extension, and hang the tire.

So - the question is - How much wheel travel is too much?

Some people want a stiff suspension and 4 lockers, and just count on the one tire's traction to be enough to propel them, and the center of gravity to be low enough to prevent rolls, yet high enough to have adequate ground clearance, etc.

A front coil sprung live axle for example is normaly considered better than a T-Bar sprung IFS.

The T-Bar sprung IFS provides down force throughout its range of droop motion.

The Coiled Live Axle provides initial downforce, and then relies upon gravity for the remainder of the droop range.

Having mostly jeep experience...I'm going to go out on a limb here, and express my impression that a coiled live axle is better than a T-Bar'd IFS for traction and stability.

That is DESPITE the coiled live axle NOT providing spring down force for the last part of its its droop range.

According to Jeff and Porshe, the IFS is going to have traction, and the Coiled Live Axle is for Ramp Fags, as it has no real traction once the coil reaches its full length, and the axle is merely drooping due to gravity.

They claim a "drooped by gravity" live axle has "Zero Traction" once the coil or leaf pack is no longer pushing it down.

(I think the faint amount of spring push at the limits of down travel are not that meaningful anyway, even before the spring loses all force...so the last end of the travel range is not significant anyway on the way down either. (Or the T-Bar would be a hot ticket....etc)...so that its spring force is more academic than important at the bottom of down travel.)

I think the small amount of down force left in a leaf spring at the bottom of its down travel is soon negated by the up forces imposed when the leaf spring has to bend more, PULLED DOWN BY the tire, etc...INSTEAD OF the leaf pushing down the tire.

I think Shackle swing is a good thing that adds wheel travel...they seem to feel that a shackle should be a solid bar welded to the leaf end - as swing means the leaf pack is "disconnected" and therefore has "Zero Traction".

So - We disagree as to the value of a "drooped by gravity" live axle....I like'm, they hate'm.
