I just was thinking, about the discussions on Shocks and the heat fading they get , during racing.

What about using a heat sink to cool them off quicker? I found this on Ebay. (See Photo) Its not the right ID, but illustrates the what could be done. If a sleeve, with fins, was wrapped around the shock, or reservoir, the cooling area would increase by many times, 50%, 100%, or higher.

In the electronics industry, there's a heat sink compound used, to transfer heat from a component chip, to a heat sink. You can see it on the processor, of your computer. Most times it's a white colored goo. If this was used between the shock and the heat sink, it would transfer the heat more efficiently.

Better yet, the reservoir be made with cooling fins.

Great thought Bearfoot! It would be a cost effective way I would think. Don't they use these to wrap around oil filters to pull heat off an engine oil too?

Yes, thats what the one in the photos is for. The material is a aluminum extrusion.
It could be anodized any color.

We used something similar on Electric R/C cars to keep the motors cool.

Yah, that's what I'm talking about.

I came up with the idea too so I made up some billet shock coolers on a lathe. The only problem is they take to long to make on a manual lathe. I approached a CNC shop to ask about making them and it was just too much $ unless I had 500 of them made. It was a pretty cool design though. The one I did make was made out of a solid 3" billit of 6061 T6 about 8" tall with 1" deep polished horizontal fins. I also was going to use heat sink paste to help transfer the heat into the coolers. I'll try to post a picture if I can figure out how. I really am the crazy "OLD" man and computers and me don't get along.

So you had the fins going the other way. Thats a lot of machining dude! I guess you could use a parting tool for most of it.
I can see why they used an extrusion. They can just saw cut off what they need.
Some one has the material sitting around. I'll snoop around on the web and see if I can find it.

I found a clamp on cooler/heat sink that might work. What is the diameter of a Fox 2.0?
It comes in blue, red, or silver.

the Fox shocks have a 2" OD. I just mic'd mine

How hot are your shocks getting?

I have FOX 2.0 Air shocks on my Honda Pilot and over heating is not a issue I have even run down a power line road that was nothing but whoops for 5 miles straight just to see if I could over heat them, they get no hotter than any other shock, fade was not a issue.

I talked to a few shock guys and they said stick to the FOX oil since its 0 weight the affects of heating the oil does not greatly affect the tune of the shock.

Adding remote reservoirs leaves the shocks just full of oil and heat generated by compressing the nitrogen is then on the other side of a diverder piston in the reservoirs, the shocks run much cooler.

I have played around quite a bit with these shocks over the years some is documented here Fox Air Shox central if you think about how these shocks work their is a ton of stuff you could do, by adding external flow controls to the shocks you could have adjustable compression and rebound control, by adding another reservoir you could have adjustable ride height and adjustable spring rate.
