Crawler Canyon Presents: Shock Talk

[@jayleeson8517]

Excellent information there Mr Canyon. Can you now do a follow up video on how to recognise what way a shock needs to be tuned in relation to what you are observing as the car reacts with the environment

[@TheOtherSock-728]

^^^^THIS!!

[@watch-box]

I made the mistake of trying the desert lizards out on one of my cars… …I say mistake, because now I have to change all of them. They look great, perform fantastically, and you get more tunabillity in the box than you need!

[@themountain59]

But some tend to leak after a while like mfs😉

[@EddieDesigned]

I'm pleased to say that after 2 1/2yrs of leaky axial scx10iii shocks, between your recommendation of tru-blu and the modification i made to the seal packs, i am now 3 months leak free! I really do enjoy these tech talks, so much info to soak up and lots of tips you won't find elsewhere :)

[@dave-iq3dq]

The Element shocks use the same size o-ring as the Associated 1/10 racing vehicles so you can run factory team x-rings. And as always use some green slime.

[@danweiss1371]

On my desert lizard on the special little ball cup I use a very small piece of fuel tubing in between the flat head screw and the shock. This allows my shock to move more freely. But still keeps it retained when running it upside down. Try it you might like it. Lol, keep up the useful information!!! look forward to your daily videos

[@CrawlerCanyon]

I've gone to using the same little o-rings that I run on bodymounts to give the shock that wiggle room when double-sheared. Fuel tubing is pretty OG, most if not all of the 8ight shocks on my go-fast rigs use silicone fuel tubing as shock bushings.

Writing this about five minutes into the video, I have to say, perfect timing. I just started my LCG build today, and the one thing I really still need to learn more about, is shock setups, and knowing this channel, I reckon I'll know way more once I have watched this. :)

[@gmummy]

Nicely articulated, pun intended!

[@Doug_Morgan]

Your tip about factory take off parts at Jennys RC was very helpful. I have been looking to replace my Axial CJ7 100mm shocks with some 90mm shocks. The stock shocks are too tall, under damped and under sprung. It wallows around like a drunk and the long shocks make a top heavy truck even worse. I wanted to get GTS shocks as I have never had one leak whereas all the Axial ones I have had leak. Downside is cost but Jennys had a set of six 90mm shocks off the TRX6 Mercedes for only 53 bucks. They come with the correct pistons and springs I need. As a bonus I get 2 spare shocks as it is a set of 6 shocks. Thank you very much for the tip. 😎

[@fejwe]

This is exactly the video I needed. I’m now deep enough into RC to really want to understand it better. Springs and shock oils are pretty opaque to a newcomer, or at least this one.

[@brianmorrison2846]

If anybody was wondering the ZOKU with a power wagon cab still out performs the SCXPRO, but it could be the driver. Currently testing tires amongst the 2. Tusk, deepwoods, fossils, and the too soft baja pro x I think I bought the wrong ones.

Don't let the people of the internet know! There are many who still claim that the Phoenix is a trail truck.

[@derrickhays3627]

Thank you for this I was wondering how to "damp and spring" a shock for best performance but watching this I now get there are too many variables for a "white paper" on shock set ups, you have to tinker to fit your rig/terrain and desired effect. Never cease to learn something from you thanks!

[@Andy_Yates]

This is pure gold. Not only does this help me when I go to service my crawler and buggy shocks, seeing how you do the bladder shocks will help me when I need to do my drift and touring car as they are bladder. On my Yokomo big bores, I did the slide the bladder from the side thing so I don't trap air. The bladders were translucent so any large-ish bubble was visible. It looks like compressing the piston a little bit created enough suction to hold the bladder in place. I've seen the race folks use those vacuum pumps for pulling the air out of their shocks. The fast guys tell me they can feel the difference.... I'm still a rookie so I'm happy when I'm not traction rolling or having bounce landing jumps. The finer details still escape me

[@GrimJerr]

Great video, if for nothing else but confirmation of methodology, never hurts to brush up on the basics.

[@VLevi89]

My only issue with desert lizards is the spring selection..... Everyone always says how aswesome that there are so many springs included, but I found most of them useless. It's soft/hard/stupid hard. I wish all of them would be on the softer side to give me some tuning options, but I only able to ran the softest ones. To be fair when it comes to crawling only, it performed really well, but I didn't liked the way it moved on the trail. Tried different oils but I just coudn't get it right, and get tired of making a mess every single time, so they ended up in the drawer for now.... Good shocks but not for everyone.

[@CrawlerCanyon]

I agree, and would like to further lodge that complaint against most every other shock mfr. out there-- I have bins of springs 4lbs/in and heavier, with no idea what those things could possibly be useful on. Luckily with the DLs, picking a combination using the three lengths of soft springs are useful enough for most builds. And for sure, the Lizards need inappropriately light oil for trail use, I would think maybe 20wt, or re-drilled pistons.

[@trevorcourt1403]

Same I found that

[@sammiller8497]

​@@trevorcourt1403i know what you mean about the dl springs to soft to ,too hard , im going to try stretching the soft spring just a bit , that should stiffen them just a little

[@edwestbrook989]

Great info! Thanks for this!

[@lastcreations8845]

Traxxas ultra shocks also :) limiting shocks using orings or fuel tubing, spring limiting on the other side of the piston takes weight off the tire. So less weight applied (unsprung) to rocks when at the limit/through travel of the limit spring. With hard limits oring or fuel tubing as soon as tire hits it is on main spring tension + full unsprung weight. just something to think about.

[@JC-Nor-Cal]

I do love to gain knowledge. Thank you for this video Mr.C.

[@brianmorrison2846]

Currently running 5 out of 9, 1/10th rigs with D/L's. But the proline 1/24th oil shock is currently my favorite shock. I'm looking for 1/24th D/L's

Traxxas slash front shocks with crawler spring cup and spring works super good. The spring clears the body. Running 50w on scx 10 3

[@CrawlerCanyon]

Ultras are super-economy Big Bores, essentially. I never had a problem with Ultras leaking, I just had a problem with blowing the caps off on rough landings. Shouldn't be a problem on crawlers.

[@dragonsland7]

Thank you so much for sharing. I have a full interior with action figure in my TRX-4 2021 Bronco. I only have brass portal covers up front for weight and some SSD wheels. Was curious what you'd recommend for the best performance on a heavy rig like mine.

[@CrawlerCanyon]

I would think that (sight unseen and weight unknown) you'd be alright with either the stock springs and a bit of preload, or at most one rate up in the front-- so maybe try the green band (TRA8040) all the way around. I would go up in oil weight to maybe 40wt, or maybe go to the alternate hi-flow pistons (TRA8261) and try 70-80wt. There's a tiny chance you'll need up a rate in the back to the blues-- like I said, I'm guessing on the weight.

[@morercthanclassy1543]

The shafts between the scx10ii and capra shocks interchange, desert lizard seal wok on the capra shock

[@CrawlerCanyon]

You can also put TRX-4 GTS shafts in Element shocks. Which is fun, because Element calls theirs 3x30, Traxxas calls theirs 3x47, and they're the same length. Now the DL seals in Capra-- THAT is good stuff, which I will be trying posthaste. Not having to rebuild Axial shocks every few months sounds like a dream.

[@morercthanclassy1543]

Thanks for this. I’m building a new comp truck so I can definitely use this shocking knowledge 😂

[@TheAmericanUhate]

Check out traxxas part number TRA5461 Variable damping kit. I used them in my UDR to have stiffer up travel & faster down travel. Basically makes them a 2 hole piston on compression and a 4 hole piston on rebound. Not needed for crawlers, but is good on go fast vehicles.

[@CrawlerCanyon]

RPM used to do this as well. I still have some of the split pistons somewhere. I remember another one from back the day that used the "flappies" like the Traxxas setup. I don't miss the days of drilling out piston holes to fine tune the rebound.

[@FeralRC]

Is it bad that I run 90wt oil on a 1/8 12 pounds crawler? Or what do you recommend

[@CrawlerCanyon]

There is no golden rule to oil weight. Some shocks in "stock" form will like lightweight oils, some require heavier. If you get really into shock tuning (drilling out pistons) you can tailor them to use whatever oil you'd like. If the rig is performing in a way that's favorable to you, then 90wt is perfectly fine. I personally try not to run anything lighter than 40wt (516cst) because the thinner the oil, the faster it's gonna leak out.

[@jimbocreationsbu8203]

[@tiborbeetles1882]

Have you tried tuning the MST shocks that come on the Jimny? I have both the plastic ones and the alloy versions that come on the CFX-WS. The latter are crazy light so I think need thicker oil but the MST plastic CMX/CFX ones I find a bit over damped so may need thinner oil? Btw the MST shocks have proved excellent at not leaking oil, but I did make them with green slime.

[@CrawlerCanyon]

The stock shocks reacted well to that ubiquitous 300cst. The TC70 Option Shocks from MST were diff oil hungry, and are running filled with 5000cst. Slow leakers, which is nice.

Really educational vid, thx!

[@ScimPeep]

Any thoughts about the Traxxas TRX4760 (series of L, XL and M too). They look very similar, yet do not have big bore in the name. Diameter of piston, rod, cylinder all look the same on pictures. Is PTFE coated, but doesn't have anodized in the name.... is quite a bit cheaper though 2/3rds of the 2660 price...

[@CrawlerCanyon]

They were (are?) a cheaper alternative to the Big Bore. Same PTFE coating, but smaller bore and no nitrided shafts. My guess is that the ones you're seeing online are NOS, as the PN# no longer brings a result in a search at Traxxas. So I'm pretty sure they're discontinued. Have never seen one in the wild, I don't think many people knew they existed. And they're about $3 a pair cheaper here. So not much motivation.

[@vb9300]

Silly question about the desert lizards...My lcg trx4 sits decent on the gts 90mm...low enough for me. Now if I were to upgrade to the desert lizards..say to the 100s or 110s...and if I were to step them up as you do, would I base my length on the compressed length to keep same ride height? If you go to YR site, they give a normal, compressed and extended measurement. Figured Id ask the master of RC

[@CrawlerCanyon]

Yes, off of the compressed length. You don't want to gain downtravel at the expense of uptravel, or worse, ride height. If the collapsed shock is longer than what you have now, you're raising your CGH by that amount, and nobody wants that.

[@themountain59]

Actually its not so complicated...spring rate is defined by the car weight, accordingly you chose the oil weight. There are people who don't use oil in the rear at all(like the guy from Gspeed) ...its try and error for what you want the car to do 😉

[@CrawlerCanyon]

Not in crawlers. For every guy not using oil there are five not running spring cups or springs at all. I consider that approach to full droop a thing I call "not trying," but to each their own. As I said, if you're ripping off of jumps the relationship between the oil weight and the spring rate is critical. I've got shocks running the softest springs I can find (0.4lbs/in) with 80wt oil in them.

[@themountain59]

[@CrawlerCanyon]

I've gotten the whole gamut-- one set doesn't leak at all, another set bled as if stabbed from the first filling. They need bigger holes in the pistons and ~80wt and then it's golden.

[@thindigital]

@@CrawlerCanyon I need to rebuild them or just get some more lizards and slap them on. For fellow listeners my top tip for tuning lizards is to wind the droop spring onto (or off) the shock shaft, don't mess about taking the piston head off. If you mount them upside down you can even change springs with the shock body still attached to the rig, the oil just stays put. Harbour freight picks are very handy to fish out the suspension spring from the shock body.

There's always the old tried and true (and was in another comment somewhere) fuel tubing. Either use it as a bushing/spacer, or just cut a piece the width of the opening on the axle and use it as the shock pivot itself.

[@Br0rB]

So, I built my Injora LCG build today, and it's pretty much done, just need a receiver and to hook everything up, and to cut and paint the body. I used the tips for the DL shocks from this video, and they feel amazing. The flex is next level (at least compared to what I've done before), at about 14cm in the rear. May be a bit much, but I'll try it out. I went from a box of parts to a roller in a day, which I'm pretty pleased with. It's rocking a lot of brass on the front axle, and a bit of overdrive, a Rhino ESC and 9imod outrunner, a 9imod servo, Proline (yay) Predator Super Swampers on some heavy-ish Injora (300g each in the front and 250g each in the rear) wheels with my own 3D printed inserts in the front, and Proline Dual Stage in the rear. I also used your tips to doing bladder shocks, as that's what comes on the RGT I took the DL shocks off of, and put the stock shocks back on. I had filled those the wrong way previously, and wasn't super happy with them, but after doing it the right (your) way, they feel amazing too. They have never leaked, and they have a nice, soft-ish spring. The holes in the pistons are quite large, so I filled them with some 700CST oil, which seems to be a good choice. If you haven't checked those shocks out, you probably should. They came on the RGT EX86100 Pro.

Confirmation bias is gonna make your brain go, "these are amazing!" but they are not functionally any different from shocks that are a quarter the price. I can put together 3 full sets (12 shocks WITH tuning spring assortments) of 2660s for the same price as a set of 4 Kroniks. Back in the days we called products like that "sponsorship stuff."

[@nandafernando6779]

Please review the SO96

[@nycr6biker796]

Full bump. Not full droop. Full droop is a jacked up suspension.

[@CrawlerCanyon]

Not how we look at it. Droop is the total amount of suspension travel below ride height-- so only downtravel. A "full droop" setup is sitting at the uptravel (compressed) limit of the shocks, so the dampers are "bottomed out" when the rig is sitting neutrally. I don't think anyone is running a crawler with the shocks at or near full extension.
