A suspension should NEVER be limited by the shock's travel. A shock that
limits travel would be an ex-shock soon enough. Your suspension's travel
should be limited by spring compression and ultimately the bumpstop.

In TJ as in almost every other vehicle without leaf springs, the suspension
is limited on compression by the bump stops, but when expaded, the
suspension is limited by the shocks. That is because the force needed to
limit the suspension when fully compressed is much larger (weight of the
vehicle plus the downwards momentum of the vehicle) than that needed to
limit suspension travel when fully expanded (just the axle weight plus
downwards momemtum of the axle).

In TJs, the shocks are what keep the axles from dropping for several more
inches before they are limited again by the track bar and arms.

The compression side bottoms out before the expanded side reaches the
