20 years on the hard 4wd trails of AZ, CA, CO, NM and both MX BCN and Sonora. A couple of hundred miles on the Baja 1000 route with a bed full of camping gear did one suspension in. And there's a lift/helper leaf in there.
Struts and shocks can last maybe 50-100k. If you’re beating the crap out of your truck you might be on the low end of that scale. Maybe that’s what they mean?
