amazing video, thanks for going this in depth! I appreciate my car even more now!
Awesome stuff, makes it so easy to understand. Is there a video on how to maintain the 4C suspension system to give it a better life span?
Excellent explanation! I’ve always wondered what that “sport chassis mode” does. Now I know.
Very nice explanation! Now i get it. Thx 🙏
Very nice viedeo. Now please make one on how effective is the advanced mode ☺
Some feedback: Put the first 2 min on the video in the end. If I came to this video without knowing who you guys are, I would most likely have skipped the first 2 min or just clicked of the video. This would make the video flow better imo.
Vikingstål Motor also change your name. Gregson is a terrible name.
Rediscover Film gregson? What are you talking about?
Reminded me of a Expresso Machine Head Unit Solenoid. 👌. Engineering relatable.
I bought S60 2008 with 4C suspension. That's crazy how hard suspension can be 😲. I prefer Comfort on highways but when i want to go faster on corners i turn on sport mode ✌🏻
Thanks for the great video explaining how the Four C system controls the damping in the shocks. However, I think that this is also integrated with other components to create the full Four C experience. I would love to know what those other components are and how they all work together.
I want to know as I have been told that I can only replace the springs on my XC70 with OE parts as otherwise, they will mess up the Four C system, so I would like to understand that.
Thanks for the explanation & cutaway! ...looking to see if anyone has retrofitted the 4C system to an older wagon!
Glad you enjoyed it!
I'm loving my 04 v70r but quick question. When are the sweatshirts suplosed to ship I order mine a long time ago and still haven't received it
The valve isn't just either open or closed but cycles quickly depending on road conditions and the chassis setting selected.
Yes, I wondered (suspected) that it would be PWM controlled and modulated with almost infinite variations of dampening.
Good video nonetheless.
Great video I Love how the 4C system works.
Having owned two 2012 S60's one with and without the 4C system it makes hell of a difference to the chassis dynamics.
I personally love it in advanced mode so much fun in the twisties 😂.
So maybe this is because I drive mainly on straight highways, but I don't fell much of a difference on my 2011 S60. Can you feel the diffence of everymode? I just repaced my 4C system last month and I can bearly tell a difference and I'm not sure if that I'm just getting a pleacbo effect.

I have a 2004 S60R and there is a huge difference between the three modes.
Most of the time I use comfort cause Aussie roads are crap, but when I fling it through the twisties hitting sport or advanced really stiffens the car up, but can be really harsh over bumps.
Advanced also puts the gearbox in sport mode and changes the sensitivity of the accelerator pedal.
They had to be broken in, it seems, because now I can tell the difference.
@@johno9507 Does really gearbox changes when in advanced mode?
@@Kimii99
Yes with the automatic transmission in Advanced mode it changes how firmly the gearbox changes gear and it also shifts gear at higher rpm, as well as holding gears while cornering rapidly.
And when you select 'manual mode' the torque converter remains locked and the car drives and feels more like a manual gearbox vehicle. 🙂🇦🇺
You guys should of tried the bilestein b6 and b8 mod ! Good educational vid!
Great idea! We have to find some and tear it apart!

I have a 2011 Volvo s60T6AWD and I want to install coilovers but what is stopping me is that I don't want my dash go crazy on notifying me about the service required!. Can I just cut out the the 4C tube and keep that piece along with the cable connected onto the car ? Or will it still show on my dash that there is something wrong ?
Is there a budget oriented solution to fixing these, is it just a matter of replacing the solenoids and fluid?
Hola.. Una pregunta.. Sabría decirme si esta suspensión se podría anular para poner una normal?.. Gracias un saludo.. Me ha encantado su vídeo
Hi, question I can buy a s80 with has originally four-c Shocks but now has non four-c shock... would this be a problem? And drive less smooth then a non four-c s80?
Hello thank you so much for the awesome video ! indoor opinion what would be the safest mode to put the cars suspension in for the safest operation and the least amount of wear on the struts. Don't get me wrong I am of the belief the belief that if you don't use it you lose it so I enjoy the car and with 255k miles on it im damn proud of my rare bird . for context its an 06 p2R AT in titanium grey metallic with the nordcapp interior
What brand did you replace the shocks?
Can 4C shocks be refurbished/reconditioned???
How does 4c compare to a set of bilstein b12/b16 kit?
This is a very good informational video, I never knew how exactly Volvo was able to make the 4C system work. I always just thought it was some alien technology!..well at the time I guess it was alien technology since nobody else did this.
These look dead simple yet they're utilized in a very complex way. It sort of makes me wonder why these shocks are $400+ freaking US Dollars.
You 100% sure the little plunger with 0-ring is sliding in and out between settings? Looks to me like that's a fixed component, and the flow is controlled through the other holes around the circumference.
if it's on or off, how are there three settings?
is the 4c system worth it? I really want it, but fear problems.
oh , stuck in sport mode. What a problem to have !!!. mine is ALWAYS in sport. forever
Saying that it's stuck in Sport Mode isn't accurate. It's in a static state, non-adjusting. Sport still adjusts/reacts
Advanced, on the other hand, doesn't adjust at all. The rest of the 4C system does(brakes, traction, AWD) but not the struts.
no, i was joking, i meant i alway put mine in sport mode all the time
I figured, I just wanted to point out that it isn't quite the same thing. Having driven an R with a non-functioning 4c system, it blows.
When mine worked, I was always in advanced, now I just use a KW coilover kit ;-)
So is it accurate to say its stuck in "Advance" mode?
Is coil over is better then 4C?
is it fixible ?
Thanks for taking them apart so i dont have to, but the solenoid valve is continuously variable. I have live damping stats if you haven't seen it yet. th-cam.com/video/xWUR4rfEeTA/w-d-xo.html
very good explanation of the accelerometer. Are you a teacher? Maybe you should think about being one
I thought 4C just made breadcrumbs
Almost $500 PER PIECE (front)!!!...
SL, did you guys replace them with genuine ones? o_O
Yup. All 4 were replaced at the same time.
Nope it's not. Just google a little, 170$ / each Monroe C2510 / 1512
Video starts 2:00
i found a pretty good pdf on the 4C if ya want it drop me your email.
do you still have this ?
This is kind of what scared me from getting an s60r
You mean aside from the angle gear? ;) That's what freaked me out.
Great video when are you going to do some mods to the V70?
Stay tuned to tomorrow’s video at 10am
How's thst angle gear?
My buttons work but I don’t feel any difference in my 2004 S60R.
David Bello your shit is broken the. Advanced is ridiculously bumpy. Comfort is very soft and floaty, like a Cadillac. Sport is in the middle. The differences between each setting are very obvious. If you can’t feel them, your system is not functioning.
I wouldn't call it revolutionary, unless spending 2k for a suspension refresh is considered revolutionary.
Svenskraft nobody had this in 2004 when they brought this out. So yes it was revolutionary. You think $2k is bad. Try refreshing a car with failed air suspension. $$$$
Rediscover Film actually gms vastly superior and less complicated magnaride came out in 2002.
Must be a SAAB fanboy..
@@EDHBlvd mercedes had active dampers as did bmw
