I was just at the OFNA web site and saw that their next shocks will have a 17mm bore. Sooo... we had small bore, big bore, super big bore...... What's next... Ultra Super Gigantic Big Bore? In a couple of years the shocks will be as big as coke cans at this rate. Does the amount of oil that the shock holds really make that big of a difference? Couldn't you achieve the same change in the rate of dampening by using shock pistons with different sized holes? I just wonder if this isn't more marketing than science.

There is someone selling 17mm shocks on ebay. He gas been selling these for about a year now.

if by 17mm shocks you mean LRP big bore then these have 17mm external diameter. internal is just 15 like losi.

more oil will heat up slower in theory but was told by our top racer that in reality does not matter as shock oil will heat up in few minutes anyway

No they are 17mm ID they are from the SH-LRP truggy and or an upgrade for their buggy.

wallot

then why the description says "The inner shock piston measure 15mm in dia."
and the look same size as losi shocks

however LRP site says 18mm big bore and the shocks really dont look like 18mm inner dia.

They will keep getting bigger as long as people continue to waste money on them..anything bigger than 16MM for buggy is just added weight and totally unnecessary

Not sure about the other ones, but the new OFNA shocks are a 17mm BORE. Quote from their site: "At 17mm pistons these babies are big and ready to ride over the bump and jumps."

i do not think they will get much bigger.. 16mm is fine with me

What they really need to be figuring out a way to independently adjust high and low speed dampening.

Someone is trying, there's a thread here about some new Italian shock that has outside adjustablilty..most people think its a scam though...I'll find the link and post it

I have read through that thread too and there are a lot of skeptics about the true adjustablilty of the Italian shocks. Several people on that thread were throwing around ideas to make R/C shocks more adjustable. Hopefully they can come up with something.

I think at some point you do get to what I would call diminishing returns (A point beyond which the application of additional resources (more oil) yields less than proportional increases in output (better dampening)..) The funny thing is that on most tracks (smoother European style..smaller jumps, not really blown out) the bigger shocks dont really offer any better performance than the "old" big bores..remember 13mm..From just watching the buggies and the way they take the jumps and the blown out sections the Losi seems to be the best or at least one of them and they are running 15mm and it just seems to be perfect, not to big, I do think that the trend seems to be bigger than the 16mm but I dont think it's necessary..now on the shocks and the variable dampening..or the lack of it, I have been involved in the hobby for 25+ years and I have seen several attempts at this and for the most none have really worked as advertised, it seems to have been as successful as progressive springs have been....the problem is how quickly they need to react, everyone seems to want to make the COOR and Desert trucks as the "poster child" for their suspension systems, if you do the math to make it close our jumps would need to be 2 feet high and our wash board sections the size of a pencil, then you would need to slow our trucks down to about 10 to 15 mph..under these conditions you could make the valving work..but the speeds we are going..scale speeds here..it would be in the 180 mph to 200 mph....it's just the speeds that the shocks have to work under its just hard to get the valving to keep up and actually work..then you work in the "diminishing returns" theory it comes down to just how much $$ are you willing to spend to maybe go 1/10 of a second faster a lap..knowing that one aw shit wipes it all out..

What size are the Losi LST shocks?

Yea, run Muggy shocks on your buggy or truggy.
