Replacing shocks ??
This is why I keep reading this web site.....
Thanks again
On a twin tube low pressure shock (non-performance) the piston always has to be at the top.
That's a disadvantage of that shock design.
On a high pressure (performance) shock design, the shock can be mounted in any position, even sideways.
So if an engineer determines a piston dampens better at the bottom, that is the way the shock will be made / produced.
On Ford super dutys, with Bilsteins, some of those the piston (and
boot) go at the bottom.
(the shock usually will only bolt on one way anyway because the bolt holes are different).
So, for the most part, it's normal for the boot to be at the bottom on some vehicles.
(look on any offroad race truck, the pistons are always at the bottom).
