Largest shaft diameter is 8.77mm and largest bore is 14mm Is there a reason as why you want to know? Curious what your trying to dampen.
I was asking because some new SC kits I have seeing lately in "Radio Control Car Action" magazine are featuring big bore shocks. What I understand is that more oil is better and will not break down as easily or quickly.
More oil is better in some instances, most manufactures have gone to a larger bore to combat "foaming" or emulsifying of the oil which inherently causes it's weight to go down or become thinner and in turn produce less dampening because of this. One way to combat this problem is more oil capacity which alot of companies have gone to, but this also adds weight to your rig and "sprung parts, another which I prefer is using a bladder and a bit heavier oil, in doing this the bladder holds some pressure against the oil so that it has to overcome pressure to foam and also being a thicker weight when it does foam it still has a dampening factor that suits me. The larger bore shock is easier to tune, but the small bore weighs much less and the less sprung or moving weight you have the better.
I wanted to try the poll thing. Curious to see what people are doing in this area. The biggest shocks I ever saw were on some Losi truck but I don't remember what it was called. The shocks must have been the diameter of a Kennedy half dollar, or at least an inch. That would be silly on a 1/10 scale SC truck, but I'm thinking 14-16 mm might be good to try.
You probably saw a losi LST, those are some of the largest bore shocks in the RC industry. Small shaft diameter though.
The biggest thing to remember in shock tuning is rebound, rebound and compression. You may have a larger bore design that holds more fluid then that of the older small bore design, but if your shocks are improperly built this causes an unbalanced rebound and makes your suspension not consistent. Sinister is correct in the aspect that the development of the large bore shock was to fight the issue with foaming from rapid movement, think of it this way. the biggest thing to remember is to keep your shock matched, this will allow your rig to feel more consistent throughout the day, and when it comes to dialing in your compression and rebound well that is a whole write up in itself. If you are interested in learning to tune your shocks I can do a write up on what I have learned through the years. And Sinister can vouch when it comes to set up that is my strong point.
I don't know about the other folks, but I would be interested. There are so many shock oil types and viscosity values not to mention aftermarket shocks available. I was hoping to see some other votes to get an idea of what people here are running...unless it's some secret. If I didn't ask the right questions in my poll then make your own with better questions.
Problem is EVERY truck and Every person use a different setup, your question is very vague. We need to know what kind of truck. Take for instance a slash, first thing to do is JUNK the shocks and buy some aftermarket ones be it from integy or from the Traxxas big bores, when it comes to something like a jammin sc10, well the shocks that are on it are respectably the best in the business so there is no reason to replace them.
I'm running proline powerstrokes on my slash 4x4. They are a little more expensive than the Traxxas Big Bores, but had good reviews.
I am just running the V2 blue shocks on both my SC-10's. I am planning on cleaning all of them out tonight or tomorrow and adding new oil. I am also installing the bleeder caps from the FT shocks so bleeding them isn't a pain.
