Which 4 link is best for air suspension?
ฝัง
- เผยแพร่เมื่อ 7 ก.ย. 2024
- Before setting the pinion angle , we look into the geometry of different 4 link suspension systems to see the various effects on pinion angle when the suspension moves up and down.
I explain why I feel that a parallel 4 link is the best solution for air rides with lots of movement and different ride heights. Then finally we weld the back axle brackets in place!

Your work is awesome . In France, nobody try to do things like you. What a pity, it's so fun to create with what you 've got in your backyard! Thanks for your videos, very good for the brain!
Merci beaucoup! I know a French Swiss guy that creates with back yard stuff and his name is also Philippe🙂
Man, Diff……..
You really have evolved this channel into a whole load more than a Ratrods channel.
You are teaching so many concepts that many of your viewers will be able to apply and transfer to their builds.
Thanks again for all the education.
Thanks man, appreciate your words. I'm happy if I can manage to pass on a little knowledge.
A key aspect of these videos is that you don't need complicated stuff to put together solid engineering.
Yes man, that's what "forest engineering" is all about!🙂
With all your visual aids you must have been a school teacher at one time. Very helpful.......Thanks for teaching us!
Pleasure, happy if I can share some knowledge. Never was a school teacher though, they would have fired me😀
The forest engineering is awesome, and the effort put into explanation w/training aides shows you're not just another pretty face but there's some gray matter that works great. OG's unite!!!!!!
Thanks. Got a few brain cells left, but the pretty face part doesn't work! Haha. OG's rule!!
Your drawings of the differential possible setups was excellent. Best diy build on TH-cam.
Thanks James!
I’ma broken record, but i love watching you professor Div. I learn something new every episode. You are a master explainer among all your many talents. Thanks yet again! 😊👍👍
Thanks brother. Happy if I can share a little knowledge and inspire
That's the best explanation I've ever heard about 4 link. Looks like a winner. Thanks for sharing 👍.
Thank you Tim
7:12 Extremely well explained. You went to a lot of trouble with your model but it helps to make it very clear. Kief!
Thank you Roger! It helped to clarify things for me as well 🙂
Div its coming its coming alone very nice so far. cant wait to see more on this project. Keep up the great craftsmanship an hard work
div. fab On. weld On. Keep Making. God bless.
Your excellent forrest engineering explanations are beyond comparison on YT.
Hey, thanks for the support! 👍And thanks for the great compliment!
I love how you take us into the classroom and show the theory in action...have a lekka one brother I am off to the next lesson
Thanks brother. Glad you are enjoying my carryings on!
Honestly Div, you explain things very well. If I understand what your doing - and I do, your doing a great job. Have a lekka one Boet
Happy to hear that man. Then it is mission accomplished 🙂
I love that your going with the watt's link. This is the same setup I want to run on my truck. (Parallel 4 link w/watt's link) You do such nice work!
Thank you! We'll build the Watts link in the next video
Short and sweet today but still lots to learn. Thanks Brother for the knowledge shared
Pleasure. Happy if I can share a little knowledge
Lekker Boet! Diff you are the real deal. You explain things so well. Love your work Pa!
Thanks boet!
Thank you for the lessons on a 4 link rear suspension system.
You are welcome Tom!🙂
Thanks again, and I'll see you on the next one! 👍
Very nice tutorial on the four link designs. You make it so simple to understand.
If it helps you, I am a happy man!😄
I wasn't planning on it, but I learned something! Cheers from the shed
Always good to learn something 🙂
Your the metal work teacher I should of had when I was in school, you make interesting content as well as cool rat rods
Thanks man! Think I would have been pretty rebellious teacher...
Your attention to detail is outstanding! Really enjoy your projects. Keep up the good work Diff!
Thanks man! Makes me happy if you enjoy it🙂
You are One Smart Cookie... Div. Keep Up the Great Work
Thanks man. My wife dont think so! Haha
There is only one way and that is the Diff Way. Lekka Diff thanks for sharing and explaining what you do. Take care.
😂 Dankie boet!
Awesome! Can't wait to see the watts link fabrication 👍
Thanks! Video will be up on Sunday
I really dig your style man. I’m glad you chose a watts link. It’s gonna be sick.
Thanks Hellguy! Busy with the Wats link this week, will post video on Sunday
Always enjoy your videos Diff. You have a great knowledge and I learn a lot. I also believe your the only builder on TH-cam that starts a project and finishes it. Keep up the good work
Thanks Tommy. I try to get stuff finished yes.🙂
Thanks for the effort ! If you ever get bored doing what you do You would be a fantastic teacher cheers for the demonstration
Could never be a teacher, will teach the kids too many strange things 😂
@@ratrodsafrica the powers that be are teaching the strangest.....! I'm sure you could do no worse 😉
@@masterofnothingfabrication 😅
Very interesting forest engineering explanation Dif. 9:07 😊
Thanks brother
Looks cooler every episode
Thanks man!
You've done a masterful job in building this suspension,,One thing that I want to input is that yor transmission and rear end doesn't have to be at the same angle because your universal joint will compensate though no doubt overall it would be best..Always the best overall work I've seen on youtube..Paul from Ohio..USA
If the two angles are not the same, you will have vibration when the driveshaft is turning as well as early U joint failure.
If the angles are too far apart the slip joint will not slide correctly.
Thank you Paul! I have to disagree with you. You want the transmission angle and pinion angle to be the same, but those centerlines do not have to line up (within limitation). This is to avoid vibration and weird oscillations. Check out this video by Aaron for a great visual demonstration: th-cam.com/video/YgNZfIR-8Ng/w-d-xo.html
Spot on brother!
I enjoy your videos immensely. I learn a lot!
Thanks man, happy to hear that!
I’ve done the exact same thing with explaining front suspension geometry. Excellent job bud.
Thanks!
I was so hoping you were going to say "i'm going to use a watts link", and then you did...nice!
Yes, video on the Watts link build will be out in an hours time!🙂
Looking Good Div. Thank you for sharing. Interested to see the Watts link. Keep the content flowing. Well done.
Thanks Ish. We'll do the Watts link in the next video!
Thanks for another cool video Div! Take it easy...peace🍺
You are welcome bro!
Howzit from a fellow Mosselbay resident.. found your channel yesterday.. awesome stuff keep it up.
Howzit Richard. Thanks, welcome to the shop!
Great classroom exercise Div 👍
Mnr. Devilliers, you definitely need an electric powered remote controlled chain hoist for your workshop. With that addition your happiness will increase greatly.
Wayne is my remote controlled motor! Haha
I just bought an LS1 5.7 aluminum short block with its heads and and bunch of other goodies to swap into my 2010 335i. It's staying manual, but I'll be shaving a ton of weight also swapping to RWD.
Good work dude 🤙
dude your knowledge is simply amazing!
I like what you just showed me about the penguin angle that's gonna help me in the future on my four Link set up. Love your videos
Thanks!
Always learning something watching your videos. Thanks so much. Keep up with the videos.
You are welcome. Thanks
It must have been chilly there in Africa i see you are all wearing your hard hats ... great video , looking forward to seeing you build a watts link ! ! " with lots of speed holes !o!
Thanks man. Yes, our winter is here!
Well dangit Diff! You just learned an old fart something new. Carry on brother!
Hey Bob. Exchange of knowledge my man, I been learning some stuff from you videos too🙂 The day we stop learning is when they put us in a box😅
Howzit Div,
Mad PAD skills... it makes so much more sense on your design...keep up the awesome work....that engine looks good...can't wait for the 1st start up... keep safe and warm ...and gooi🌽🌽🌽
Hey, ek vergeet nie van daai mielies nie! 😂 Thanks boet!
Lekka Div great explanation on 4 link
Thanks boet!
great work again Diff.....
Thank you Rob
Lookin great and working awesome, nice work Div
Thanks Geoffrey
Hey Dif,
Good video. I can't wait for next week, because I'm think I may build a Watt's Link if I go with the parallel 4-link for my current project. Right now I'm still in the planning stage. I have most of the bits, just need some time and a little cooler temps outside. I'm sure glad You Tube allows myself or yourself to go back and edit you message. Right now my glasses are (put in swear word here). My new ones should be here next week, I hope.🤠
Bart
Thanks Bart. Know about the glasses, have the same problem every year! 🙂
Nice piece of engineering Div. Albert's portrait looks good on the wall but what about his brother Frank? See you next video.
Thanks boet. Only Frank that impressed me had the surname Zappa 😂
Lekker Forest Engineering 😮
LOOKING GOOD !
Thank you!
another great videoi love watching you working out the probloms has you go have a nice one diff and your family
Thanks Robert! Now if I could only figure out my wife on a piece of plywood...😂
Take your time. It's just cool.
Thanks, no rushing here🙂
Love it! I’m always learning here. 👍🏻👍🏻
Thanks boet!
I really enjoy ur videos the way u explain all of what it doin I great I really appreciate how u explain things ur a great builder and teacher I have learned a lot from watching u it seems u n ur fryer having cooler weather than here n the states but keep up the great videos and till next time my friend 👍👍👍👍
Thank you Eddie. Glad you are enjoying!
Dang Mr D I just reread my comment and I meant to say friends wr having cooler weather lol
Looking good brother....headed to Arizona for family summer vacation soon from Texas...may try finding a project in Arizona
Thanks boet! Enjoy that vacation and the warm weather. Its winter here now, brrr! Yeah, go dig out something in the rust free desert 😄
Looking good brotha enjoy watching what u come up with
Thanks, glad you enjoyed
Looking good 👍 👌 😎
Thanks Dwayne
I personally don't have a lot of experience with a 4 link system, so thank you for the education on that subject. And as always looking good my friend!
Thanks, happy if I can share a little knowledge!
Un aplauso para ti Duff... has realizado una clase de geometria, y tu dices forestal... jaaaa, realmente excelente!! Mis respetos!!
Thank you!
Love it deff im looking forward to the end result!! Keep jamming brother. O hay rat rod bob check this out. Lol two fellas that get it done.
Thanks brother! Me and Bob got some things in common.
@@ratrodsafrica ya but man you are definitely next level. We won’t you at sema show lol just the thought and exaction on some of your stuff. Jut wow !
Killer work man
Thanks man!
outstanding explanation!
Thanks!
Awesome Div!
Thanks Robert!
Very Nice ... Build On
Thanks!
Awesome job brother!! Looks amazing!! I have a 2018 gmc I want to lower not sure what way to go as I live in Canada 🇨🇦 Montreal Quebec!!
Looks great I thought you were installing rear Air bags. If not but your installing shocks you could use coil overs and a pan hard bar. You were saying your pinion angle changes due to up and down travel. I thought torque is what changes pinion angle.you set it a little lower than your trans angle so when you accelerate the pinion angle moves up to meet your trans angle.. your car your build I'm sure what ever you come up with it's probably right take care diff looking forward to seeing what's next.
Looks like you got this engineering business down good luck with the rest of the build keep on keeping on 😊
Thanks, I try🙂
Dude this channel is awesome. Love the step by step. Keep up the good work.
Thanks bro!
I like your work doing it on a budget, looks like it’s getting cold down your way.
Thanks! Yes, our winter is here!
If you do the chassis and Bad Chad does the body you'd have one awesome ride!
I don't want a truck full of Bondo!😅
Rofl
Great tutorial on your 4-link design. I enjoy watching your videos.
Thank you. Glad you enjoy my stuff
Hello Div, another great program, really like the 4 link set up, good work Boet. Take care and have a Lekka day. 👍
Thanks boet! Have a lekka one.
From the looks of the hats ,shoes and coats, winter is approaching in SA. Starting to get hot here in central US. Another good tutorial on 4 link geometry. Are you sure you have never been a professional teacher ? Perhaps you should have with your abilities to explain . Good Job man!
Thanks boet. Yes man, its cold now. Nothing like your winter, but cold for us!🙂 I could never be a teacher in the modern world, will kill too many kids😂
great explanation again Diff. thanks.
I am allready waiting for the next one, because I shouted PANHARD BAR in sterio with You, but thinking about it I wonder how the behavour will be in this set-up.
and how it will maintain the center of the axle in full movement. if You see what I mean. hmmm interesting.
maybe a P.A.D. visual demonstration from the rear perspective in the next video. 👌👍.
Aha! I'm shouting Watts link Jan! Better behavior than the Panhard bar for my application. I will do the PAD thing in the next video or 2.
It looks awesome
Thanks
Great work! Now it brings the question, how the hell do some cars have 4wheel steering like some corvettes? It's crazy.
Thank you. Yes, that's a whole different ballgame 😅
That’s exactly how I would do it ⚡️
Great minds think alike Johnny! 😄
Beautiful job Diff, looks awesome.
Thank you Keith!
Loved the video Boet!!! The forest engineering and visuals were a awesome touch!!! I again learned a ton from your videos!!! Im gonna end up with some degree after obtaining all this knowledge Boet!!
By the end of the year, you will obtain the degree in Forest Engineering! Need to find you one of those funny hats😂
@@ratrodsafrica thats for sure Div!!! Its awesome your passing on your knowledge!!
hi dif, you made that look so easy. great work
Thanks Kenneth
It all makes sense to me .
also makes sense to use watts link.
Happy to hear that Robert🙂
Love it
hi my name is johnny blaze i live in forida i love your video your doing good it s my best show to watch good job get back to me i what to visit you i need a vacation see ya
Howzit Johnny. Thanks man.
Good Man adjutment 👍👍
Another good video Diff KEEP THEM COMING 👏 🇺🇲 👌
Thanks Donnie!
Constructed and designed like an engineer. You must have a background in Mechanical engineering Dif. Is there going to be an issue with the drive shaft angle? It seems the elevation will cause a negative approach angle from differential to transmission or am I just not seeing the whole business out of ride level. Will we see some kind of dampening for the front suspension? Very interesting design. I am sure we are all wondering how well it will ride and handle. Love your program and how you present the ideas. Thank you Diff for your time. Very interesting!
Thank you Doug. Yes, well observed regarding the drive shaft, some challenges ahead. But we will figure it out.🙂 I will fit shocks up front in the original location.
Thanks for the education. I'm struggling with the angle of the drive shaft. The transmission and the differential are at the same angle, but won't the drive shaft hit the cross loop that holds the ends of your torsion bars?
Keep the videos coming, I learn one item on every one. Have A Lucky One. 🤠
The plan is for a 2 piece drive shaft with carrier bearing underneath that cross member. We'll find out how it works 🙂
Correct me if I'm wrong, Diff, but from the angle that I am looking, it looks like the driveshaft will cut through your beautifully made crossmember with the holes in it. I can't get a good enough look to be able to connect the tail shaft to the differential yoke. I hope it is an illusion! Great video as usual!
I'm thinking 2 piece drive shaft with carrier bearing. We will see how it works out
I was also thinking that was a good fix if possible!
👍🏻🍺🍺🍺 Pass these out to your friends
3:04 The quote I like from Einstein is "Man has a finite mind, but lives in an infinite world."
I see you with a watch/skull cap on. I guess winter is setting in.
Ah man, Einstein had a whole bunch of great quotes! That one is good too. Yes, in the Southern hemisphere everything is the other way round, winter is here!
@@ratrodsafrica Thanks
Awesome
Thanks!
Now add the stabilizer bar from center of different to keep it centered from moving side to side
I will be building a Watts link in the next video to prevent sideways movement
Plywood Geometry 🤟👍
Better than paper cause you can make it move around 😀
You will also need a lanyard bar to keep rear axle centered .
Panhard
Yes. Or a Watts link. We will tackle that in the next video!
Center diff to inside frame rail
Kan nie wag om die volgende episode te sien nie..
Nice!
Thanks man!
