Increase ARTICULATION - FOR FREE | Let's Talk About Sway Bars on Toyota 4Runner, Lexus GX470 chassis

In this video, I show you how to get better flex and articulation on your Lexus GX470, Toyota 4 Runner, Toyota Tacoma, Land Cruiser, etc. FOR FREE. Again, do this at your own risk, but I think the off-road benefits are massive after experiencing it myself. This modification has to be the most effective free mod I've done, and, inconjunction with the PCK panhard bar correction kit I had installed in the last video, the rig is sure to have monster flex even without long travel suspension.

Good call on backing up and not running over your friend

[lostwithasmile]

Just took mine off a 4 runner and what a difference this makes off road. It felt as if is was floating over the surface at times. I have bilstien 6112 up front and now I can finally feel the improvement they make. Do it!!!

[jonbrandt]

It will. Always run a sway bar on the solid axle, when mixed with IFS. The solid axle does not need help to flex. The rear sway bar will actually leverage through the chassis and push the front corner down that is lifting. Another tip is to make sure you run extended sway bar link arms. Particularly with any lift or extended shock length. Otherwise, the bar will bind before allowing full wheel droop. I've been considering running a heavier rear bar, like the SuperPro from down unda'.

Great video with great shots of the improvement in articulartion w/no front sway bar. Been trying similar things with my GX470 and thought I'd share where i'm at. My build is much milder than your awesome setup (running 2.5" lift w/265/70r17s) but similarly heavy with a 200lb rooftop tent, winch, stuffed drawers etc (6k lbs?). After some experimentation, I've ended up with a Nolathane 24mm HD rear sway bar on the middle setting with the front sway bar set up for easy disconnect when I hit the trail but hooked up for day-to-day pavement work. Can't recco enough removing the front sway bar for off road - the articulation and levelness of the vehicle is great and the ride is so buttery smooth. Also can't recco the HD rear enough - even with all that weight up top, it handles surprisingly well. Thanks again for posting your vid - lots of great ideas.

This seems like a no-brainer traction upgrade for off-road. The benefit would be even larger on an open-diff vehicle which needs both tires of a given axle on the ground to put down any power at all. The only problem is the on-road performance. I'm going to try it on the road to see how bad it really is. It might not be the worst as long as you're not lifted and top-heavy.

Removed the sway bars on my '05 tundra double cab. Shortly after took it wheeling in Helen Ga, drove it like a maniac on the winding roads in the mountains, lots and lots of sharp corners and steep angles up and down hill, even off road. Not once did it ever feel like it was rolling excessively or did I even lose traction or have any issues on stock suspension & cheap small street tires. The only time I can ever really feel the lack of sway bar is when i PURPOSEFULLY pretend to avoid an imaginary object in the road extremely abruptly. Then and only then do i feel a ton of body roll but still i dont think id be able to roll the truck even if i tried. I have full confidence in the truck without sway bars even going 80/90 on the highway. No body roll or issues. Sway bar will be staying off.

Great video! I had seen Kai's video, but it's nice to see it performing in the real world. I'm about to lift my 4Runner, and I don't do a ton of off-roading, but I will probably take the bar off when I do go on trips. If I like the way it handles I'll probably just leave it off. I used to drive my solid axle first gen Grand Cherokee with no sway bars, if I could deal with that I'm sure I could deal with the 4Runner lol. (I miss that solid axle articulation so bad!)

[anonim]

What about adding more controlled tests that would let us to compare it better? Probably would be interesting to see how lifting one of the front wheels would look in those three scenarios ( original sway bars, no front sway bar and extra stiff rear sway bar)

[EchoWC]

Just found this channel, but I also have the thicker rear from Kai's video.
As others have stated, what a new/weird feeling with the extra articulation

[jp_gill]

Was nice seeing how much of a difference it made on trail, the body is SO much more balanced. Just had my stiffer rear sway bar delivered this past week, can't wait to try it out myself.

[KareemAdnan]

One of your best videos! Great explanation! 👏

[paladain]

You can spray or brush on a used automotive oil to those rust spots to help control them

[KraziAzn]

removing my front sway in my 100 was the best free mad ever. Just have to make sure I drive slower on the fwy lol

[DavitGiorgadze]

Nice video. Please tell us couple of words about disadvantages at highway, what is maximum recommended speed. Also why you linked ADDCO rear sway bar, do you use it? As i understand you have both sway bars removed.

[andrescherrez]

This trick work in all vehicles. I diconected the sawy bars in my suzuki vitara now there are not ways to stop

[owensanchez]

I removed the front sway bar on my 04 4Runner and kept the rear on. On road I feel a little bit more body roll hence why I kept the rear on but Offroad it makes a world of a difference. I just disconnect my rear when I get to the trail.

[GHohn]

Engineer here. Going stiffer on the rear bar doesn't increase *total* articulation. It cannot do so, mathematically. IN short, you have only so much weight acting on so much spring rate. More sway bar stiffness (effectively more spring rate) causes less TOTAL articulation. Always. Let's freeze frame at 6:00 to better understand why. In this situation, the rear rear is drooped low, the left rear is compressed, the right front is slightly compressed and the left front is airborne.

If you added rear sway bar stiffness to this situation, what happens? The rear wheels do not change position since they are both on the ground. Which means the frame/chassis will respond to the increased sway bar stiffness instead of the rear axle, which is fixed in position (the axle moves the frame, not the frame moving the axle). The frame will have less of an angle relative to the axle. This means the frame and body will rotate clockwise (as viewed from rear in 6:00 view). This tends to RAISE the left front even more so.

Remember, your front IFS is attached to the frame. You cannot move the frame on the opposite direction (via stiffer rear bar) and expect the IFS attached to it to not move or to move on the opposite direction.

This is because a sway bar is a form of spring, but it acts only on the *difference* between left and right sides. A stiffer rear sway bar (more spring rate) will reduce rear articulation and total articulation.

You are mis-applying the lessons of Kai's video. Kai is correct. Your conclusions from his video as applied to this situation at 6:00 are not. Go back to Kai's video and note the effect on camber and frame angle as a function of sway bar stiffness and then think about what's occurring in your particular case at 6:00 and how it differs from Kai's CTI ramp setup.

Is there a way to disconnect sway bar without removing it? If the bar was cut in the the middle & ends splined with a moveable splined connector. How's highway driving without the anti-sway bar?

[krunckap]

How do city and highway driving feel with the front sway bar removed? I also have the eibach stage 1 up front

[bobbymorgan]

Did you ever install your heavy duty rear sway bar. Just wondering how it is working out. do you have a link of where you purchased it ? Thanks for the great videos
