Original Struts?

My 98 4wd’s shocks and struts have at least 140,000 miles on them—I can verify this as I drove those miles. It’s possible they have as much as 251,000 (meaning they’re OEM), but I didn’t own the truck for those first 111,000 miles so I don’t know. There are no leaks and they seem to perform well though the ride feels stiff.
Can struts/shocks last this long?
Thanks

 

I’d say it’s possible if it’s never been offroad

 

Maybe if it’s a pavement princess in Arizona but I’d still be counting my lucky stars

 

It is an Arizona truck! It's been off-road in 4WD low maybe twice a year. Very little rock crawling--mainly snow, mud, and the extra traction needed for steep, gravelly roads.

 

Just because you are not visually seeing a leak doesn’t mean the hydraulic fluid in there isn’t decomposed to the point where it’s essentially like water . Most shocks need a rebuild at 30k . 5-10k with some off road use and 5k or less with a lot of off roading.
It’s also what you are willing to deal with as well. You can be happy with your blown ass shocks forever if you don’t mind your truck driving like a fully loaded fed-ex truck on the highway, or bottoming out constantly off road and you have to squeeze your butt every time you hear that metal on metal sound as you mash through little bumps.
