Thanks for your hard work! This sort of data is very difficult to come across on the internet and i hope you understand how valuable this is for us nerds out there!
It'd be nice to be able to engage the sway bar on demand. It'd be helpful for off-camber traverses (probably not so useful in FL, but VERY useful in the mountains). Also...does your KDSS squeak?
Excellent video. I am about to change out my front struts on my GX today - was searching for whether I really need to open the shutter valves to do release the KDSS. Looks like all I need is a floor jack to push up on the front KDSS actuator to assist with the coil over swap out. We'll see. Please comment if you agree or if there is additional rationale for releasing the shutter valves for my mod!
You should check out my other kdss videos explaining the function of that system. Most of the time the accumulators are open and you can manipulate the cylinders independently
@@MudPuppyOffroad Thanks, will do. I just swapped out the coilovers w/o the need to open the KDSS Shutter Valves and w/o removing the sway bar. Just used a floor jack to help manipulate the KDSS front cylinder (lower the passenger side). Will be publishing that video soon on my channel.
Any idea how to get the KDSS light off after deleting? I've tried disconnecting the KDSS ECU and fuse which didn't work. I'm more of a mechanical guy, but would measuring the resistances across the pins of the accumulator and adding resistors that match onto the harness get rid of the fault? BTW I deleted my KDSS and designed some brackets for a OEM style rear sway bar and welded those in. Rides great and minimal body roll.
Welp…you just saved me a few bucks. I was planning on purchasing the switch. I really appreciate the objective evidence you presented here. I see that you plan on deleting your KDSS. What do you plan on replacing it with? That would also make a great video if you haven’t already planned on it. Cheers 🍻 Edit: Just spotted your KDSS delete video. Subscribed
Working on the delete RN it's a bear. I'll post a video in a few days hopefully. No sway bar up front. OEM sway bar rear with solid links and a manual disconnect
So KDSS is off when driving straight, and only turns on when you quickly turn the wheel while the vehicle is in motion, not because the vehicle is moving greater than 15mph like DrKDSS advertises. So the only difference the switch would make is preventing KDSS to activate while turning in motion. Driving fast through a trail usually means numerous and quick steering input. Does the KDSS system deactivate/reactivate between steering input intervals quick enough that when compared to a complete KDSS deactivation with a switch, does the difference in ride quality become negligible?? Toyota does advertise the KDSS valves opening and closing thousands of times every second. So perhaps yes. In all, unless one can immediately feel a distinct ride quality improvement with the use of a KDSS switch without having to second guess themselves, its a complete waste of time and money. And it seems like thats very much what the case is.
Yes off-road the system turns on and off pretty quickly based on the LED I installed. I played with the switch for hundreds of miles off road and I can't feel a difference. That mod is definitely a gimmick
@@MudPuppyOffroad Seems like a switch that activates KDSS would be more desirable, especially when going through an off camber portion of a trail. You should make such switch and sell them haha
Hey man, great educational research! I see that you are running large spare tire with KDSS, are you worried that the rear sway bar and the hydraulic pump run into the spare tire under off road articulation?
@@MudPuppyOffroad yeah I have a 33 under there and the distance between it and the sway bar is almost the same as yours. So no issues goi g through rough terrain with the big spare in the back or you yeah?
My 4Runner front ram has begun to seep oil. No dash lights or issues yet. I am thinking of removing the front sway bar if that will prevent the ram from continuing to leak. I’m wondering if oil will continue to seep past the piston if there’s no swaybar pushing up against the ram. Again, I’m hoping someone has first-hand experience with the same situation.
Did you try offroad by removing electric wire harness from the kdss actuator on the frame rail? So it will not engage whatever the steering wheel speed?
Yes, but it seems not, if it’s changed with steering wheel speed, it’s not completely turned off. Because kdss actuator is the only output that controls kdss pistons right?
@@telmenluvsandorj3217 I think you have some kind of misunderstanding. From the factory, the system turns on if there are high g's or there is steering speed. When I disable it. The system remains in float mode. No matter what, there is no voltage available to close the lockout solenoids
@@telmenluvsandorj3217 the signals that close the solenoids in the KDSS accumulator come from the KDSS computer. So if you remove power to the computer, there is no way to solenoids can shut. It's a pretty simple wiring diagram.

Glad it's useful to you! Took me a while to pull all this together there's so much bad info on the forums
can't wait for e-kdss ❤ 🙌 ... great video 😊
Wow incredible info! Thanks for your hard work on this!
My pleasure!

Ive been thinking about that, could wire it up pretty easy... but you'd have to engage on flat ground prior to going off-camber. No squeaks yet

@@gerard4441 kdss is not robust enough for serious offroading regardless. Deleting mine

I checked all that. This spare barely clears the sway bar and cylinder how I have it positioned. I'm deleting kdss anyway though

There will still be pressure in the ram when the rear cylinder locks up. The system is cross-linked. But it may help slow the leak
@@MudPuppyOffroad did you see the new front ram replacement in the work from Dr KDSS?
Did you try offroad by removing electric wire harness from the kdss actuator on the frame rail? So it will not engage whatever the steering wheel speed?
I unplug the KDSS computer which accomplishes the same thing prior to adding my switch which also accomplishes the same thing

How does it turn on if we cut off electric power from the kdss actuator by pulling its harness?

You hate those kdss fan boys huh. 😅
It's great for soccer moms. I hate people that push gimmicks and don't even understand the system
