Why I avoid secondary paved highway

How rough is your highway ride.

For shits n giggles I took the highway that is a more direct route than the gravel roads I take and decided to video it. It's pretty sad but this is considered a normal secondary highway. Figured it was neat watching how hard the axle gets banged round. So the video is of a video on laptop because I haven't figured out how to upload it properly. But it gives you an idea. Btw inside the cab ride sucks bad. I take the grids because I can do 75mph and the paved you don't want to even do 60mph. This is also why I have so many shock issues I think. And it was -25° today. Anyway thought I'd share. Ones a couple min and the other is under a min. One facing front and one rear

Looks like that would heat a shock up quick, especially over 50-100 miles. Maybe cheap shocks every year or so would do the trick ? Or even adjustable shocks. I had some Rancho 9000XL's i put on our 04 2500 Ram/Hemi/Auto & loved them. When not towing I set them on 2 or 3 all the way around. When towing our 10,500 lb camper we had, i set the rears on 9 (max) & the fronts @ 5-7. Doing that made a HUGE difference over the factory shocks. Only had em on about 6 months, then traded it on our PW so I can't comment on long term reliability. I got all 4 & a steering stabilizer for about $450.

I'm working with bilstein to get a shock valving together for this. Partly why I took the vid so I can show them what they are up against. The valving I have in the 7100s is good for the really nasty bangs and bumps but it just can't keep up with the 1/2-1" high speed bumps

Is it perhaps the compound of the seals? It can't handle the extreme temperature variations. What ever the sled manufacturers use may be the answer. Perhaps fox or oliens would give up some info.

Yes the fluid is gong to be key. The issue is going to lightweight oil created dead spots in the shaft travel at high shaft speed where you end up with zero dampening. So these little bounces end up uncontrolled and the axle is allowed to "bounce" For a short distance. On the grid roads though where the axle travels more the truck just floats. Quite a contrast.

How much air you have in your tires?
