Tech Talk: RC shock mount positions explained 

Instead of making something complicated even more complicated, you kept it basic, straightforward & easy to understand. Thank you! 👍

This is the best most accurate description of how shocks work at different angles without using the word “perpendicular”.

Best explanation ever. Was searching for a long time a simple video to understand the basics. And you did it perfectly.

One of the best suspension advice videos ever.

This was massively helpful and the clearest explanation. Thank you so much.

You are the definition of a GREAT teacher, I like how you kept it on a low dimension to make it easier for many of us to understand Liked and Subbed!!

I always move my rear shocks in one hole on the tower, I like the gain in roll thru the corners it gives. Sometimes depending on model, I will go in one on the front tower if I need a little more steering. But I generally try to keep the positions on the arms in the middle, that seems to be the most "relaxed" or not so aggressive spot

just got into rc racing and just doubled my knowledge in 10min! great video, can you do one on tires please!!

OMFG! Now this is what i want to see more. You make it sound so perfectly clear. Just what @cory mcgee said. Thanks for the quick and simple explanation. No jibberjabber just straight to the point.

Dude I’ve been struggling to find exactly what you have showed today for ages! As someone new to the hobbie things need to be simple so we can progress into it better.

Very helpful, I like how u explained how it all works. Thanks dude!

I watched this to make sure I know what I’m doing. I can in fact confirm, I know more of what I’m doing now. I set up my slash 2wd for on road with the stock shocks and set them inward so there is more travel and I am more able to adjust the preload properly to allow for the load of the car to transfer correctly. It also allows for less weight to be transferred off the inside rear wheel under breaking and turning to allow for better braking in the corner and better acceleration out of them. Next step is softer compound tires and a low cg chassis

Thanks for making the video, makes sense now.

Good information I sent this video to a few off-road racers:)

Very informative video thanks !

Thanks for explaining all that. Makes sense to me now.

All good I actually learned something from your video

Awesome Video! You just got a new subscriber!

Great video! Really helps explain the fundamentals of shocks and positioning. Question, could you overcome some of this with stroke length?

Thank you. Learned a lot

Thank you for the very straight forward and simple explanation... Love it... But I hv a question... I understand when we need the spring softer or harder, can u explain when do we need shocks feels more progressive or feel more linear?

Fantastic explanation 👍👍 What if the upper holes on the shock tower is further in than the lower control arm inner suspension hinge pin? Softer or harder?

Great job. Very easy to understand your awesome tutorial.

What are the best shock absorber positions for jumping and gravel riding? For slash 4x4 for example.

My suspension is way too inconstant. I will make these changes right now! Thanks :D

What do you recommend for a 1/5 modified n latemodel shock step-up for a circle track??

Awesome advice

Really useful vid, thank you

Good work, thanks!

Great video!

What experiences do you have by fitting the shocks in front of the a-arms?

Thats a great example

Very nicely detailed 👌🤟

Well explained right to the point thank you

Nice Video, My 2wd slash I had to move the bottom of the rear shock in to soften it up and kept the front further out for more stiffness, helps in gravel and turning, thats for sure. Pavement, I now get the front wheel lifting off the ground during a fast turn, rear is bit too soft for pavement lol

Hi where did you get tha screws for suspension arm

Thank you for the info..

curious to know who you got this in depth view of physics. excellent job coaching us.

i have a dodge 2500 4x4 with a 10inch lift. ive been wondering all of this because its super bumpy. im fabricating an.airbag set up for the front. the previous owner had switched it over to where the shocks are in a different position far from The Middle .. also there about two times as big as the stock position. I got everything set up for I can get the bags in there but as it is right now the shock mounts will not bolt up to top of the screen buckets .. I was wondering if it would be okay to change the position where they mounted from so that they will attach at a different point .. I think I'm just going to fabricate amounts that are in a totally different position from where they were . your video explained it very well I wish it was a little bit more in depth but that was awesome video thinking

Currently using a Traxxas Slash 4x4 Ultimate and all I do is a lot of jumping with it. So setting the shock on the furthest (away from the center) on the shock tower hole, and the furthest shock hole on the arm would be the best positions for jumping and to help reduce chassis slap?

Thanks for the Info..

Thank you!

Good explanation, The whole video I was waiting for you to go one step further and talk about what it actually does to the cars handling. For example: you move it in on the top and it makes the car do this, move it out, it does this. Thanks for the video!

If I lay down my rear shocks, will it increase traction at the rear or vice versa?

Thank you very much!!! Well done :)

Don't know if this was asked already, but do these rules apply to solid axle as well?

Good video 👌

So if you had a lot of bumps and jumps you would mount to the inside and if you were going for speed on flat straights to the outside?

Thank you.

Older video, same good info. Thank you.

Would this make it slightly taller

What about the turning knob of the the shock ?

Whats the top piece called that you put the screw or whatever in the top part of a shock I hace a redcat blackout xte pro

Basically a basic concept that basically behaves basically like a lever that basically does basic stuff....basically

This is interesting but I was left wondering what happens with the springs. You move in and leverage increases for softer but you compress and shorten the spring increasing the preload kind of making it stiffer so you have to keep the preload/length of spring the same by adjusting that for full effect. Also, when you move in you reduce the shock travel length reducing the dampening you get from your oil shocks. That could be adjusted with thicker or thinner oil in the shocks. I'm a rc newb but it's not so simple and it's fun to play with the suspension.

Tks GOD BLESS YOU

Basically! 😙

What the difference between putting the on the opposite side

Only thing missing from this video is how the adjustments will effect your ride. Stiffer gives understeer softer gives over steer. Not sure if that’s true I just was giving an example.

So for asphalt racing I want it to be all the way on the outest holes?

Wouldn’t you have more leverage the further you are from a fulcrum, in turn making it easier to compress giving it a softer suspension setup/feel.

So with droop. Say I want to increase droop in the front and I’m starting at middle middle top and bottom ..outer hole on top and inner on bottom? Same truck (22t 4.0 btw)

Drinking game - take a drink every time he says basically lol...BUT a great explanation...ty for making this video...

Soldering iron works well. Use fat tip and apply to fastener (screw/bolt) you wish to remove that has loctite.

Thanks , never understood this

If ur doing straight speed run what’s recommended ???

And also by doing that move to to outside hole it’s more likely to be a looser set up.

I got all my questions answered before 4 minutes mark

👍

Does shock mount positions affect ride height? The ride height at the front of my car is too high so need to figure out how to lower it significantly and wondered if changing shock mount position would help.

Does any of this affect the height of the car ?

Watcher keep in mind when moving shock location. Make sure the shock rod doesn’t fully extend a full preload because you will bend shock rods from being over extended. You can adjust the h arm set screws to help shorten the shock rod length

Is making the arms stiffer better for jumps? or would you want it soft for jumps?

Could u pls help me in one question ? What is 10,10,7 shock location? I got no idea which angle is 10 10 7

Man I love just chilling out and learning something new from you every week! Cheers Razor RC! 🍻

forward to 2:48 to get to the point. I swear these utubers love to hear themselves talk

Clear explanation but I would like to hear more about how it affects the ride. How do I prevent my car from flipping on turns???

Have you considered putting the shocks upside down to lower center of gravity? Shocks are upside down on motorcycles and MTBs for example.

I was looking for answers on how to adjust positioning but you didnt go into how these positions actually will affect car control and performance during different maneuvers - i did notice that youve just repeated information again and again in slightly different wording but with no link to stiffness or softness affecting handling. Appreciate the info and just giving some constructive criticism from a viewer and beginner

And when you move the shocks to a new place you can change the preload on the springs or even the spring rate with new spring. Also if you soft the ride but in general like the way it handles you can bump up the weight of the oil. Same goes if you move it out and it’s too stiff but you like the spring rate you can move to a lower weight oil. I got a lot of practice with physics and fulcrums growing up. I was much taller and heavier than my classmates so I had to sit closer to the fulcrum of the see-saw. 😉

Basically just basically, basic....... basically.

Moving the shocks in towards the pivot will raise the ride height. Moving away from the pivot will lower ride height.

Mmmmh, crab legs!

Good video. But I'm sooo sick of hearing everybody overusing the word "basically". After hearing it the 15th time in the first 2 mins, it's so hard to concentrate and I just keep waiting for the next time it's said. Ugh.

That has to be a new record for the word BASICALLY being used!

The key here is that setups are a clustered effect. I feel confident in saying that 99% of us could not tell a difference in moving the shock arm from T-A to T-B, or even A-B to A-C, etc. The other 1% are liars ha ha. However, it's the setup as a whole the cluster that is what defines the vehicles optimizations. To that end, I only change mount positions if I am driving on-road vs off-road...otherwise it's not that much of a difference maker (even within the cluster). Additionally, so much of this hobby is 'on paper' but in the field the results are completely different. This much I know. :-)

would have been good to go over how changing the front shocks can change the steering. You just seem to find 10 different ways of saying the same thing, when you move your rear shocks in it makes it a softer shock and when you move them out it a stiffer shock but nothing about the front of the vehicle

Great video, but too much repetition. And you don’t really explain why you would want a softer vehicle, or why you want them more linear vehicle, or why you’d want a more progressive vehicle. What do those words actually mean performance wise. And in what scenario is each better?

50 thumb up!! One is not enough

Dude your lip smacking stop

This was useless, you choose not to help anybody with this video, which is why you need to make nutcracker jokes.

Just a bunch of blabber

Ty my same thoughts all that formula stuff gives me a headache👋👋👋👋👋✌✌✌✌✌✌✌🎈🎉🎈🎉🎈🎉🎉🎉🎈🎉😁😁😁😁😁😁😁
