Oh right. So regardless of design or brand, all shocks will convert the
input energy into the same amount of heat. What they do with that heat and
how well the materials used handle it is probably a major design
consideration -- after all, a shock absorber that overheats and fails
quickly is not desirable.

Do manufacturers rate these things in terms of power handling capability
or provide temperature ratings? Do the ones available for our Vanagons
vary much in this regard?
