5th Gen Swaybar upgrade from ADDCO

[ATL4R]

Thicker sway bars are on the way from ADDCO. I emailed them a few months ago and got this response:

xxxxx, The bars for the new 4-runner should be ready in March.

Thank you,
John Wright

Probably add some quick disconnects while your at it since the the thicker swaybar takes some of the off road prowess away.

Questions for those savvy with swaybar knowledge. I believe swaybars reduce body roll when turning, and increase overall stiffness.

-How much roll is typically reduced?
-How much stiffer will the ride be?
-Won't the addition of stiffer springs (and or) shocks (like Bilstein 5100's) effect stiffness more than new swaybars?
-Are these new 5th gen swaybars hollow?

I shed my front sway bar a couple months ago and haven't looked back. Running 2.5" Fox coil overs in the front, there is a huuuuuge increase in off road performance, and only a marginal decrease on road. That being said.... I am interested to see what ADCO will be offering, keep us posted!

-how much roll is typically reduced?
quite a bit actually, its hard to put a number to it. You really notice the effect of the sway bar when doing u-turns, etc.

-how much stiffer will the ride be?
hard to put a number to it, varies with each shock / spring / vehicle, etc. One thing though, sway bars aren't really designed with the intent on "stiffening" up the front end. That is sort of a side effect of their design, their intent it is to reduce body roll by, physically linking the two sides of the independent front suspension (or solid axle) with a bar that is in effect, a torsion bar. The bigger and thicker the bar, the more torsion effect, thus, one side of the vehicle compresses and this movement is translated through the sway bar to the other side. Hope that makes some kind of sense.

-won't the addition of stiffer springs (and or) shocks (like bilstein 5100's) effect stiffness more than new sway bars?
yes, springs will if you increase spring rate, and shocks will to a point, depending on the valving, etc.

-are these new 5th gen swaybars hollow?
my 5th gen trail sway bar is hollow.

did this ever come out?

Any updates?

I am also looking for sway bar bushing upgrades for 5th Gen 4runner but no luck.

I just re-inquired with my contact at ADDCO. Late April (2012) was the expected release, but I haven't seen them in any catalogs.

I'll post once I hear anything back from ADDCO.

I've been told by ADDCO's development that the rear sway bar is developed, but not produced. I was being told two more weeks all summer. I gave up on calling. They are supposed to call me when they start producing them.

Will they have disconnects?

Will they have disconnects?

I highly doubt it. You could make some up though.

Anyone have updates? Thanks

Old thread but I got an email form John Wright at Addco today stating that if I could get 10-20 people interested in a swaybar upgrade he would put it into RD for us.

 

[jwkilgore]

If the design comes with a quick-disconnect or the ability to easily add quick-disconnect links I'd be interested. With a little advertising I'd all but guarantee selling a lot more than 20 of those.


If it's just a stiffer bar with the same geometry then no thanks.

 

[SouthernSS]

^---I agree

 

[wfo9]

Disconnects at the link will not work. The bar will chew up the cv boots and get in the way.... But if he designed a full arm disconnect (even single sided like the one I did). It would sell very well.

I really like having this setup. Performs perfect on and off road. I wish something like it was available commercially for the Toyota IFS trucks.

I did see where someone in Australia did sliding links at one time, but I heard they were noisy and they stopped making them

 

[raptore]

^---I agree

I second this!

 

[lcecconi]

addco just emailed me saying that if we can get an order of 10 or so for th 5th gen they will manufacture asap

Still Waiting .... 4R Street Swaybars

I know this is a very old thread, but wanted to keep topic open.

I've got a new 2018 SR5 (did not want full time 4wd)

It is a daily highway driver and will log 500 miles per weekend on the interstate going back and forth to the lake. Off road will be limited to the gravel road leading to boat dock and a slippery boat ramp. 4-Wheel drive likely only used on slippery ramps. Also intended is infrequent light towing, less than 3000 lbs.


I'm interested in mods to improve on-pavement driving and cornering on curvy Ozark roads and flat interstate.

Considering:

* Aftermarket sway bars / bushings (Any input on vendors???)
* 4Runner limited 20" wheels w/ touring tires
* Air bags for rear (minimum pressure most times)

I'd like to hear your input on how to make our 5th gens corner better. :frog:

I've contacted ADDCO and received the following answer to my 2/12/19 inquiry of aftermarket sway bars, " We only have the rear bar at this time.... Part#2301 (0.875") - John".

Thanks!

-On sways, KDSS would have been the best option since it comes with pretty massive factory sway bars. Sways would make a noticeable difference, but I don't think I've come across any for the 4runner. That said, I have a feeling that the cost of aftermarket sways without other suspension changes likely isn't worth it.

-By bushings, do you mean for the sway bar (to fit a larger sway)? If you mean bushings elsewhere in the suspension (e.g. urethane), that would only make the ride worse.

-20" wheels will probably increase unsprung mass, which is bad for handling. The smaller sidewalls would also be a hit to comfort without changing the suspension at the same time. I think a good compromise would be 18" with decent tires?

-Airbags - I'm not entirely clear on how they affect ride quality, but if I'm correct that minimum pressure is around 5 psi, you're effectively changing the spring rate of the rear suspension and it may not be for the better.

Honestly, I think the most you can do is to find decent tires and fill to a higher pressure (38-40 psi) and, it's a long shot, but you could explore alignment specs outside of the factory range.
