I love how detailed you are in your videos! I shows you do your research before putting your videos together. Great job!

Fantastic explanation. I've been a gearhead for 30 years and this is probably the best description I've seen of the designs. Keep up the great work!

Fantastic content as always. The rigor you bring to your vids is much appreciated!

I love the videos featuring the Ironman foam cell pros. When I was buying mine, there was a lot of of mixed info and uncertainty on the forums regarding the performance and longevity of the foam cell twin tube design. Wish your videos existed back then so I could feel at ease buying the shocks. I appreciate you showing the raw data and conclusions in each videos focus with the foam cell pros being an example of a shock design that doesn’t follow the same mono tube construction as most of the other shocks available on the market right now. Keep up the awesome work, Kai!

So much information yet presented in a way that is easy to understand. Keep up the good work!

The quality of your videos continues to be amazing. Thank you so much for the time and effort you put into making them. I learned a lot!

Tinkerer, great work! You are leading the way in off-road educational videos. By far the best. Keep up the good work.

I love the non-biased, pure information. Keep up the great work!

Thanks for the video, although I thought I knew the difference between twin tube and monotube shocks, I did learn a few things. Personally, I have had good results with both kinds of shocks. However, there is one aspect of this comparison you didn't address, and that is trail damage. A monotube shock is much more vulnerable to damage by a rock hit, because the ding can prevent piston travel past it, whereas a twin tube shock can sustain the same hit without impeding function at all.

Bilstein 5160 shocks are inverted, less chance of damage (smaller target). But a nicked rod will leak.

This is the most informative and clearest presentation on shock construction I have seen in my 30 years of working on cars. I look forward to more of your videos.

Brilliant video. Extremely well explained and unbiased. Look forward to more suspension videos. Subscribed.

Best discussion of the technical aspect of these products. Hat's off to you sir !

the internet needs more content like this! keep them coming!

I like that you really covered each aspect subjectively. Much better understanding after watching this. Thanks.

Best explanation of shock function I have ever seen. No one else ever explained the differences. Thanks!

Dude, I reference your videos all of the time with all my yota friends. Keep up the good content and continue to take your time making videos. Thats what sets you apart from other youtubers. You don’t just post tons of videos to get likes and subs. Keep up the great scientific work.

Another great video full of useful information. Appreciate the work you do in putting together your videos! Keep them up!

Excellent explanation and I loved the way you cut and drilled the shocks to demonstrate your point :)

Excellent explanation of both designs. Without a doubt, this is one of the best automotive engineering channels.

Most of this was over my head, buti really look forward to watching you service your Icons and explain the difference in performance before and after. My brain always wants the "best of the best", so I got excited watching the professional motorsports footage 😂 but you're right, I just want to hoon in the woods and haul wood and stuff

I’ve been running the Ironman Foam Cell Pro in my 2012 200 series cruiser here in Australia for several years touring and towing and it’s been faultless. It’ll definitely be getting replaced with Ironman again. Thanks for another cracking video 👌🏼👍🏼🙌🏼

Your explanation was amazing keep up the good work!

thank you for your dedication to these topics. This is a incredibly impressive presentation.

ALWAYS SO informative and taught in a way it's easy to understand ! Awesome vid AS ALWAYS :- ) !! Love the subjects and really learn a lot here..Thank you Sir !

I always wondered what the heck the foam part was of the FCP shocks. Another fantastic video!

Awesome, awesome content. Thanks for the in-depth explanations!

Great job ! By far the best channel on this topic !

Very informative. Also, cutting through the marketing hype without bias is also very helpful. Cheers!

Man this was way more detailed than the rest of the guys that explains about, twin tube and monotube shocks. And u got a new sub for this. ❤️‍🔥❤️‍🔥❤️‍🔥❤️‍🔥❤️‍🔥

Excellent breakdown as always. Your reaction when you drilled out the Bilstein gave me a good chuckle (Not that I would have reacted any differently!) Also the piston rod as a pointer was a nice touch. :)

I am looking forward to your product-specific reviews! I too learned a bit more about twin tube and how FCP differs from standard twin tube (IM nitro, Dobinson's basic and OME) construction and performance. I'm looking forward to your dissection of the Dob's MRA shocks and how they compare/contrast to others in the field (Bil's, Icon, King, ETC.). 🤙🏼

Great topic and content. I look forward to all your videos.

This is an absolutely fantastic video. Thank you very much for your effort!

Nothing like having good info from which well informed decisions can be made. Thanks for your time, and content.

Really well done video, great detailed info!

Bro, you brought in the Ideal Gas Law into the explanation. I was pleasantly surprised. Keep up the good work. Looking forward to future videos.

Absolutely brilliant video, extremely detailed and thorough, but all very clearly explained. Really interesting, thanks.

Thanks for the suspension class Kai!

Great video! I find your information very easy to understand. I think about suspension upgrades a lot and how much "snake oil" is sold to the end user. Can you do a detailed explanation comparing Digressive, Progressive, and Linear... In my short research and limited knowledge it seems Linear would be the best for daily driving/weekend warriors. Curious what your thoughts are.

You really thought me about shocks today and now i have a better idea of what to get for my ride. Thanks man! Wish I could find some remote resys for a liberty lol

Great explanation. Thank you!

Another great insightful video. Thanks!

Pretty neat video! I would add that heat transfer happens in three major categories. Conduction, convection, and radiation. Conduction is solid to solid, convection is solid to liquid, and radiation only occurs at extremely high temperatures and does not require a medium to transfer heat. So shock heat is not actually radiated, rather convected away from the oil by the solid body, then convected away from the body to the surrounding air. No radiation heat transfer occurs. Great video and keep up the good work!

Great job again Kai.... well done my man.

I have waited for this video for so long !!! Thanks dude !!!

The only channel I turned on the notifications for.

Finally someone else that has explained that the sole purpose of the remote resovoir is to lower operating pressure and create a nicer ride and increase seal and wear band life is only a side effect and that the extra cooling is only an added side effect

Great explanation and I’m looking forward to the Icon maintenance video.

Awesome video. Thank you so much for making this video. Probably the best shock video ever made. OCD here but the Ideal gas law is PV=nRT. n being mole. Keep up the great work!

Another banger of a video!! 🙌🏻💯

Great video thank you for making

Finally, someone with some scientific explanation. soooo many of the shock related youtube videos, even by manufacturers, are like some sort of "red neck voodoo" explanations about black boxes with no information about what is going on inside and how the different types work.

Dude your information and explanations have helped me understand the pros and cons of both, I've been trying to decide between Raw Nitro Max twin tubes or Dobinsons IMS mono tubes, the price difference is around $500- $600 more expensive for mono tubes but I have realised what actually suits my needs on my 80 series landcruiser is actually the twin tube, the Nitro Max has a 45mm piston and 60mm outer tube/body and some kind of bag set up to contain/separate the gas, huge fluid volume and are the 4x4 line of products from parent company Powerdown which is a truck suspension company dealing with semis, b doubles and road trains etc, I think they know what they're doing. I want something strong, simple and reliable that's going to withstand outback touring and bush navigation etc.

That “phew” got me 😆😆 great great job!

@TinkerersAdventure I have recently subscribed to your channel. Love the in depth videos. I’m a huge Toyota fan myself and just purchased my 6th Toyota truck. It’s a ‘23 TRD ORP. It’s my daily driver and sees very mild off-roading. I’m trying to decide on a suspension set up. I’m thorn between the Dobinson IMS or their twin tube shocks. If you were in my shoes which would you pick? Or would you pick a different set up all together? Like maybe eibach pro or bilstein 6112/5160? Thanks!

I sure hope you are making a decent amount of income from these videos! Your te and effort spent to make them is invaluable to so many people, even those who (for some reason, ha ha ha) do not own Toyotas.

Another great video - its worth adding another benefit of twin tube shocks on vehicles doing high speed gravel road work or likely to drag shocks on obstacles, especially applicable to rears - a dent in outer body of a twin tube shock has negligible impact on performance whereas a dented body on a monotube is usually terminal for the shock.

@TinkerersAdventure

Жыл бұрын

That is true. I actually took some footages demonstrating this but I cut that out due to video getting long. The bilstein actually took a lot to dent. I hit it with a pointed hammer quite aggressively, took about 3 good hit till the piston bind. So unless it’s a very inferior thin wall shock, gravels will not hurt it. Also, all monotube rear shocks are inverted mounted. The shock bodies are way up there, so I’ve never seen one getting scratched. Twin tube has to be mounted shock body down because of the base valve.

@travelling_two

Yes good point, I forgot that the monotube shocks are inverted, though that can lead to peppering of the piston rod if its not well shrouded. A lot of our travel is thousands of kilometres on high speed gravel outback roads which grit blasts anything in and around the rear axle.

Great video, I have a question, I have FJ cruiser with 3" life , I have changed the coilovers front and rear with dopinsons, panhard bar, UCA dopinsons , sway bar link, and put profender shocks 2.0" , and 1" spacer in front, all this for the 3" lift. But the raid is bumby and uncomfortable , should I change the shocks or what to do? Help please.

How i wished this video was uploaded earlier then i could've decision for my fast driving application. I drive a Toyota Hilux here in Asia and decide to try a monotube shocks after watching tons of video on youtube. The IFS front setup seems pretty good handling all the bumps but i find the rear live axle to be a whole lot more bumpy going over rough terrain than my standard oem shocks. Will probably consider changing the rear shocks to a remote resorvoir in the future.

It could simply be your rear shocks valving not matching your spring and mass. That plays a significantly bigger role than shock construction

Nice video, well organized. You missed some things though. Only inexpensive mono-tube shocks, e.g. Bilstein 51xx and Fox Performance, have ultra high pressure, like 250-300+ PSI. Better shocks, the owner rebuildable kinds like Bilstein 7100, Fox Factory, King, etc. work fine with lower pressures. Fox 2.0s with no res, recommended pressure is just 150 PSI, 7100s, recommended is 180-220PSI, similar with King. It just needs to be enough to prevent cavitation at high shaft speeds. The higher pressures like in the 5100s are only because it has to last the life of the shocks and the eventual pressure loss over time.... 'cause they don't have Schrader valves on the tops to set/re-set pressure like the better shocks do.

@@TinkerersAdventure I'd put money on it that even the foam-cell shock, will have a dead spot even cycled by hand a few times, with the body up. It's very hard to get a complete air-free bleed on those things. I'd be impressed if there is no dead spot body up!

I recently just put a lift kit in my 2015 Kakadu Prado with Kdss. I'm running the Tjm xgs series springs and shocks up front, with outback armour shocks and airbag man extended airbags in the rear. The entire kit, with uca's in the front, cost about $4,000 aud. So far the rebound has been harsh onroad, but performance is ok offroad. It's making me reconsider redoing my suspension again for better performance onroad with more control offroad. Lifting with kdss is often expensive and a headache. Was considering monotubes with remote res, but now I have no idea on which direction to go. 😂

Thank you for another eye opening video. How do the high and low speed compression adjusters on remote resovoir shocks affect shock performance and how does rebound adjustment play into this?

Solid video. It's really annoying and scummy how people sell products with disinformation re: lying about twin tube cavitation using a single tube

Good stuff. It may be worth putting up a phase diagram/chart for standard shock fluid to show what is actually happening (or doing a separate video on this). Otherwise its hard to evaluate what is actually happening vis-a-vis shock fade and the upside and downside of twin tube vs pressurized mono-tubes. Also, does cavitation in a damper really matter that much as the "high pressure" side of the piston (i.e., the side of the piston head that fluid is flowing into) is under much higher pressure and is unlikely to cavitate and that is the side that is doing the most dampening work? Lastly, why is it that we don't draw a vacuum on new damper fluid before installation to avoid the dissolved gas situation. I know that when I change the brake fluid on my MTB (SRAM - DOT fluid), I always use the syringe that I use to draw a mild vacuum to get out some of the dissolved gasses. Thanks.

Cavitation is easy to diagnose, but you need to test the damper on a dyno. www.penskeshocks.com/hubfs/Resources/Tech%20Sheets/TS-Pressure-Balancing-2-04.pdf
