Crawler Canyon Tech Notes: the Anti-Dive Primer. Also, shock angles!

Welcome to anti-squat's partner in crime, anti-dive. Mostly the same process as last time, only in reverse. Also, we talk about shock angle, and show you how to use... trigonometry (shudder) to work out effective spring rate.

This shock angle talk is incorrect. Even though your springs are at 90* when climbing a hill they won't compress more due to angle alone. They'll compress very slightly due to the body's weight in relation to your link travel but that's it. If you setup your coilovers at 90* to your links at full bump then your springs will be much more effective than the setup you currently have. Your axle moves directly along the travel of your links. How can the springs in the configuration you show compress any more than the linear travel of your axle?

Good stuff. I've always wondered why we angle shocks. The more you know (trigger rainbow).

[@timbertime738]

Coming from zero knowledge I definitely have a better understanding, thanks for your efforts, I'm new to rc rock crawling and have an scx24 and really wanting to climb steeper terrain but also descend them too

[@rccrawlingaddict207]

Great lesson.....THANK YOU!

It is useful to invert your reference in regards to the relationship of the frame and axle.

Each chassis (whole vehicle with body & electronic) should be tuned. That's why in our world we have Car services. Keep doing it, Jack

I need to angle my shocks, my rig is only 4.5lbs without a body (not got one yet) and i have the softest springs I could get in side the shocks (I have no budget and could only afford the Injora Mountains) That made sense to me so I must try it as there is no droop on my shocks the rig is too light. I have standard chassis but looking to fabricate one like you have. I have aluminium flat bar I can use but will probably have to use shock keys as its not wide enough to incorporate the towers.

[@StopMotionJeff]

The angle of the shock should only matter in relation to the axle path. The angle of the chassis should have no effect on the axle path. I want to see some testing on the amount of force it takes to compress the shock at different chassis angles. Pretty please with a cherry on top.

[@electronsmove]

The angle of the car does not change the spring rate. The angle of the spring is relative from the axle to the frame. The spring is resisting the motion of the axle with respect to the frame not the horizon. If the car frame is standing straight up, the axle still moves in an arc toward the frame, not up and down in relation to the table. You can measure this if you have a spring scale. Pull the axle to the frame in all orientations. The force does not change.

Well Done!

[@nathanwirth9906]

Awesome!!! Thanks a lot. That was I who asked about that and I had no idea . Very informative! Oh and have you tried vanquish’s new tires. I’m wheeling right now while I listen and they are very sticky. Surprisingly good especially compared to the garbage that came with the Phoenix Thanks again!!!

[@johnarcher9480]

More shock angle also allows for longer wheel travel for a given shock length.

[@kollinsendall1]

Do you have a dedicated shock tuning video? I’m looking for more detailed information on shocks specifically. Full droop, half droop, no droop. That kind of shock video. Thanks!

[@danweiss1371]

Again, what can I say but thank you thank you

[@Fantaman900]

Tilting the truck doesn't change shock angle, suspension moving up and down will change the shock angle and the more it's away from vertical the more it will move away from vertical during compression. Gravity pull straight down, your wheels give an equal force straight up. When you tilt the truck uphill the center of mass moves away from the front and towards the rear. As you tilt the link will also go from horizontal to vertical and as you do you take away load from the spring and on to the link. When you angle your shock you take away force from the suspension travel path and put it in the link.

Thanks. Liked and subscribed. I like knowing the rationale behind this stuff. I have a Corrupt Carbon Reaper Chassis I'm trying to wrap my head around at the moment. :)

[@ka4172]

Does a lean over shock get more friction on one side of his shockrod?

[@covecityboys]

If the distance from fwd link mount to upper and lower shock mounts is equal that is “90°” essentially. Move upper forward leverage makes shock essentially weaker. Move it aft and it becomes essentially stronger. Nothing changes spring rate or shock strength except changing springs.

[@Andrew_Red]

won't angled shocks also increase flex?

[@Bandoe72]

And ppl think this is playing with toys😂😂well it is,but there sure is a bunch of math homework🤯🧠 to get your rig runN how you like it Gr8 video
