Bilstein 5160 remote reservoir shocks vs all others

Yeah, if you're nuking 5100's, go to a 2.5 or better.

Big shock bodies gives more surface area to shed more heat, and more fluid, so it heats up slower.

Is fourwheeler.com wrong about the heat dissipating quality of higher volume remote reservoir shocks?

Your hose volume has to be less than the shaft displacement or a resi will do very little for heat transfer. The Bilstien 5160's resi's are right on the shock body so they do offer some extra heat shedding ability. If you have a 12" long resi hose on a 10" shock, it ain't going to do much.

resi's do offer more nitrogen volume and have less pressure change from heat than the Bilstiens with internal floating pistons.

b dkw1,

That makes perfect sense, now I got more research to do. 5150 are a piggy back and 5160 have a 8" hose for a 10" travel shock, based on that 5150 would be much more appropriate for what I am looking for.

If heat is the main issue, seems like fins on the shock body would be common? Wondering how to accomplish that after the fact. Not sure how hot shocks can get, but maybe some high temp epoxy?

My only issue with the 9100s I had on my Jeep was they rusted in like a month, but you won’t have that issue where you are. I beat the snot out of 5150s as well, and they never complained but I did manage to overheat them when I went out west and could run them for longer.

You have a 6,000lb truck, you need at least 2.5s with resis if you want to run in the desert.

Finning the shock body would create too many "stress risers" in the metal. Gluing a heatsink on, generally works, but not as well as a larger shock body.

Bilstien has an extruded aluminum body by-pass shock. They have ridges in them, they cool much better than a steel can. Unfortunantly, they don't really support off-road stuff anymore as it is not a money maker.
