Technical review and comparison of how much the swaybars limit Toyota's articulation; how effective KDSS actually is and how it works with aftermarket suspension mods. KDSS is available on Toyota 4Runner, Prado and Lexus GX460. The Land Cruiser 200 series is also equipped with KDSS, but it has different construction from the Prado platform.

@LexusGX460-OFF-ROAD 2 года назад

I been saying this forever. We LOVE our KDSS. It's basically zero sway bar off road and an amazingly thick swaybar on road. Car on road, truck off road. KDSS is a gamechanger...love it!! The refinements of the GX and LX are no joke or gimmick...

Most underrated Toyota channel HANDS DOWN. I wish I saw this before I made my purchase 4 years ago. I remember dealing with a buddies KDSS and being very curious about the system.

Man your content is incredible. Easily the most knowledge-dense videos on the subject. I frequently have to pause and even rewind just to digest what you said, even though your presentation is clear and thorough. I love it. Thank you so much for not only explaining but SHOWING and often PROVING your points. Thanks for making these!

Yep, love the KDSS… had a chance to compare the ride dynamics in technical off-roading between my 2015 TRD Pro 4R and my brothers 2016 Trail/Off-road 4R with KDSS… definitely noticeable. It really works well. This is a terrific and thorough video with valuable data points. Really great work here. Thanks for the many hours of testing and video production.

your videos have been nothing short of awesome, please keep up the good work! i would love for you to be able to dispel or confirm the KDSS myths about how much lift can be installed vs inducing KDSS lean from the lift kits. curious if you could dive into that one of these days? also you brought up the front KDSS spacer for the front passenger side, and honestly, i don't know if it would ever be needed for a mid travel lift. hope you can get your hands on one to test and compare.

Your videos have been amazing. I opted for KDSS when I got my 4Runner and for a while had buyers remorse thinking that it would prevent me from adding lift. I was able to lift the front by 2.5 in with no problems. This video shows that I made the right choice and your other videos helped me understand the Toyota suspension much more. Reconnecting the KDSS sway bar after shock install was a pain, though. Keep this kind of content coming.

I could have put the tires on my 17x7 stock wheels but was planning to get 285 tires before the tire shop talked me out of them. They had a recent 4runner that wanted them too and they could not make them work w/o excessive rubbing. 285s would have been a problem and the 275s look great. More rugged than stock but not excessively large. Also less additional stress on the drive train.

@sterlingburk3790 Год назад

Absolutely wonderful video. I'm happy to see other people understanding and explaining real wheel travel and what KDSS actually does. They make an electric shut out switch that allows you to keep the KDSS valves open or closed at any speed you want with a push of a button. Its wonderful.

@TinkerersAdventure Год назад

Thanks! The switch can only overwrite-open the valves, not overwrite-close the valves. This is achieved by faking a fault signal in KDSS so the ECU goes in fail safe mode (valves open), which is why the KDSS dash light comes on.

This is some really great analytics here. I’ve got a ‘12 GX460, 1.75” spacers with stock struts and 2” Icon springs with stock shocks. A lot of people asked me why I did this. Because of the math! My GX has KDSS, which most people think is a limiting factor. But here’s proof right here. Limiting yes, if you wanted to lift it 6” but I find. With my setup, full wheel droop and my articulation is better than if I had a swaybar. Great video!

@ryanschmid7940 2 года назад

KDSS is a pretty cool system for a daily driver that also goes off road. I'm looking into the DrKDSS type switches for my GX as I feel like there are certain trails where the 12mph threshold for soft/stiff is just a little slow. You want to go 15, but instead go 11. There are also more prepared dirt/gravel roads where KDSS shines. It's not a Raptor, but can maintain quite a bit of speed without feeling sketchy. The only other thing is just making sure your aftermarket parts like skid plates, sliders, and lifts don't cause interference with the sway bars. Tons of companies have these parts now.

Thanks for making this video. I always learn something from them. I have KDSS and really like the on road handling. I was pleased with your conclusion regarding its Offroad capabilities. Bonus points for talking about the KDSS Spacers and aftermarket rear sway bar! Someone already mentioned the Dr KDSS switching kit. I've also been wondering if a front passenger KDSS spacer would cause it to hit my CBI front skid plate (maybe lower with longer bolts without cutting)

@TinkerersAdventure 2 года назад

Thanks! I don't think the front spacer will change clearance to skid plate. The spacer is not added to the driver side cylinder, which is still the lowest point when it fully extends.

Thank you for this informative explanation. Based on your video about sway bars vs no sway bars, it sounds like a KDSS system that would only disconnect the front sway bar while utilizing stiffer sway bars both front and rear would provide the most balanced front and rear articulation off road, while providing better on road maners.

@ATiredRyan 2 года назад

Great information as always! I will agree that for me, long drives are no fun without the sway bar. The ride feels smoother without it due to each side working independently, and the flex is great, but the sway during long drives and even heavy winds make me hate the trip of trying to stay in my lane. Would be nice if there was a quick disconnect kit out there.
