Do we have some decent info about how long various types of shocks last when used offroad with some regularity and do we know why some may perform worse yet last longer?

Is it true that low pressure shocks can outlast high pressure shocks because they are more tolerant to being pushed too hard?

For example, OEM twin tube shocks may perform meh but they sure can last. My Outback struts were fine at 70,000 with 3,500 miles off pavement, including lots of 4x4 trails. I was beat up a couple times, like on a short day White Rim Road run, but no issues and the shocks recovered after the 2-3 occasions when I felt the car being like a dump truck.

By contrast, high-pressure monotube shocks perform better within their normal range but if you "cook them," their seals supposedly harden and life expectation drastically diminishes. True?

RR shocks are said to diminish the pressure and thus outlast non-RR mt shocks. True?

Then, rebuild-able shocks are said to vary greatly in quality with the lower-end ones having much less durable interior components. Some suspect that this is often done by purpose so that one would have to rebuild more often than actually necessary.

So...can someone actually post their info about how long their shocks have lasted (or lasted between rebuilds) when actually used offroad with some frequency at some decent though not race speeds? OEM, 5100, Eibach, OME, Dobinsons twins and MRRs, all the various Fox, Radflo, Icon, BP51? It stands to reason that rock crawling is not really an issue for the shocks so this is more of a question about easy but rough and long desert tracks and long washboarded roads.


@Jetboy ? others?

Thought this might be an interesting topic.
