Crawler Canyon Tech Notes: Why are my shocks upside down?

- We're here third hand. Someone asked another someone, and they relayed it to me. So we grab some scales, do a little math, and hopefully get to an answer. Of sorts, at least.

This is also the reason I'm such a fan of servo on axle conversions 😯
Very glad I asked and very well explained as usual!!
I firmly believe the gts works better right side up. The cavity inside the cap catches air for the imulsion during assembly. When the majority of the air remains in the shock cap and acts as the bladder does in the big bores ( more or less) because the piston can not travel up and pass the air in the cap. When inverted, the air in the shock is fully accessible by the piston when fully drooped and introduces much more air into the oil when cycling versus right side up. I've run my comp style truck with gts's inverted and normal and found it to have much less controlled dampening at or near full compression and droop when inverted.
I run most of my shocks upside down already, mostly for the CG benefit. But also the leaky bois tend to stop leaking when they're flipped.
I had no idea that emulsion shocks are kinda supposed to have an air pocket. That makes much more sense. So thankyou for this !
Oh I do love a twofer =)
It’s Tuesday somewhere, right? That makes this a TWOFER TUESDAY! 🙌🙌
I've been running all my shocks upside down for years, chasing what i thought was a few mm difference. I never expected it to be so significant!
Same. I was expecting a drop of 2 or 3 millimeters.
@@CrawlerCanyon lets be fair, it wasn't unreasonable either, a couple of mm at this scale would still make a good difference! Let alone 10mm!
The only shocks i don't run upside down are on the go fast stuff, Slash 2wd, b6 buggy and my twin hammers rock racer
Lol, I was running my Chavtechs upside down and one started leaking from the cap. Glad you made this vid. I guess I'll swap them around and see if that helps.
cut a piece of fuel line slide on the shock shaft so it doesnt hit the bladder.
Weight down low and oil seepage
Time to get to flippin shocks.
Who would have thunk it? Not me! Something else to shove into the RC storage folder.
when i put the gold 3gear with dig, how do you suggest i mount the fusion se in my ascent, should i mount the motor to the 3 gear or on the stock mount like rattlecat
Honestly, either will work. Your CG will drop with the motor on the gearbox, but your weight bias will shift backward a bit so you'd likely need to add front weight to compensate. It would be a whole lot simpler without the FMM.
Nice
I tried the whole upside down shocks but I didn't notice any difference. I didn't get as in depth as this, though. I never mess with leaking shocks so I don't worry about that. I run all element shocks fitted with x rings. Stopped messing with anything else a long time ago lol. I still have them upside down on my two comp crawlers mainly for looks 😂
Very informative. I hadn't considered the possibility of crap getting sucked inside the shock body when inverted. Still on shock theme, I've recently read or seen or watched something about a new shock shaft coating that increases performance. Instantly I assumed it's along the lines of Kashima coating on MTB shock shafts and fork stantions, to give smoother movement and some protection. Is this a thing now or did I dream it?
There are a number of mfrs. doing TiN coatings, and AE used to do "Unobtanium," so if someone wants to do MTB shock coating I'm all for it.
Been running them like this for a while just because 1 they leak or 2 a feeling. Thank you Mr C! I have a question for Friday Live but I will ask it here incase you have time to answer. How do I get over/underdrive through the axles if I buy the MEUS F10 Portals?
in over under diff gears. 27/8 front 33/8 rear is 20% or you can buy a tcase with the difference built in.
my shocks i used teflon tape on the top cap and flipped them. bone dry on the outside
my very first rc was the redcat danchee ridgerock. I read an old note in some weird forum about flipped their shocks to put heavy side down. I flipped my shock and shared it with fb community and most hadn't heard of that. i've always flipped them. not sure why others do not. my shocks have almost never leaked unless they came defective.
How have you never owned an Axial? I've never met an Axial shock that didn't leak without a full seal replacement. A buddy of mine is building up a Phoenix, and the included S8Es leak as badly as any shock I've ever seen. I've had soooo many sets of S8Es by this point, and they're all over the board. Some are fine, some might as well be cross-drilled. Every single one of them is running upside down. By necessity.
@@CrawlerCanyon oh.. I own a utb18. been waiting for you to finish that build.
they are rightside up right now. They haven't leaked. have had it for 6 months now and no leak interestingly.
Very informative video 💪😊 and I love this tech episodes.
I have a question, I have an element gatekeeper I rebuilt to a 4link back and SOA front with lay down shocks to fit my pickup body. But I have too much torque twist in that one. I want to try to turn the ring in the rear axle that you discovered in a live stream was possible with element axle. But I haven’t figure out the gearbox to have opposite rotation. Or maybe t-case in the back? You have another idea? 😊
many suspension options first, seen in front or rear the most ? shock angle, firmer rear spring, and link placement
@@lastcreations8845 the most torquet twist is in the back. I need to have the shocks lay down pretty much to fit under the bed of the pickup. And I have very stiff springs that come with the trailing arm stock on gatekeeper.
drive that bad boy
Nice 👍🏾💯
Should be called. Dr canyon RCD😎😎😎
Maths clarification: 4 x 9 = 36 grams. But the question is, that don’t you actually get 2x the effect as you are removing it from sprung and adding it to unsprung? Therefore 72gram shift in weight.. 🤔
I'm the wrong guy to ask. I can barely do arithmetic.
