Oh Im sure, but going 35-45mph on washboards for 20 miles will give a shock a good workout, I just wanted to be sure a non-remote reservoir shock can take that sort of punishment without overheating. I did it with my Rancho 9000s in wyoming, and they seemed to have held up, but I figured with the JL I'll be running 37s (running 35s on my JKUR now) and the heavier 37s will be a harder load for the shock to handle.
A good monotube shock will do a better job of dissipating heat than a hydro shock and the nitrogen inside will do a better job of preventing cavitation. Sure, a remote reservoir will do it better but I rarely see people putting them to the test. 35-45mph on washboards for 20 miles would NOT be something I'd feel needs remote reservoirs.
