Newbie Question - KDSS

KDSS is only useful when doing serious off roading. In city or highway driving it never comes into play. When off roading, it is really nice in keeping the wheels in contact with the ground, and making the ride much more comfortable -- not as much jarring when going over boulders/rocks.

Quote of the day: RE Land Rover Defender: "Someone should show this to Jeep as proof that you don't have to punish your customer's for wanting to go off-road" Car & Driver magazine, Jan 2021.

Thus, if you want to be punished for going off road, drive a Jeep. If not, drive a 4Runner with KDSS (or a Land Rover Defender).

What? KDSS is designed to give the car on-road prowess while not compromising off-road capabilities.

You get the benefit of a thicker sway bar on road! And not losing as much flex offroad below 13mph

Ehhh, not too sure about the on-road part. I have now wheel time in the XREAS, KDSS, and stock 4Runners and would say that the biggest upgrade that reduced the body roll and overall crappiness of the on-road manners was an ICON lift.

If you do drive an otherwise stock KDSS and non KDSS TE or ORP (or whatever the hell it's called now) back to back there is marginal difference in handling, specifically the body roll is less bad, but still bad.

I will say the 4Runner doesn't like spirited driving and will remind you of that repeatedly.

I love my KDSS off road, but have nothing to compare it to since I've never wheeled another 5th gen 4Runner.

That is incorrect. It improves on-road handling, AND improves axle articulation while off-road.

As the article you linked below also says.


The linked article said:
When equipped with the Kinetic Dynamic Suspension System, Toyota models provide the best of both worlds on the road and the trail. Employing hydraulics to automatically adjust stabilizer bars and lean resistance, the Kinetic Dynamic Suspension System will limit body lean when you are on the highway. When you are maneuvering at slower speeds on the trail, the suspension will soften to allow for greater wheel articulation and more freedom on extreme terrain. At standard driving speeds, KDSS allows anti-sway bars to work as normal, reducing body lean by as much as 50 percent and keeping you safe. This system runs on hydraulics without the use of complex electronics, so you know that it can withstand the beatings it will sustain on the trail.
 
Yeah, definitely will have to budget for future maintenance fees/leaks down the road but hey, that's the price you pay to play. :target:

I don't know why this keeps getting repeated. KDSS is proven across multiple vehicles and rarely has issues.

My 2015 has 75k miles and I have had zero issues with the KDSS system despite multiple suspension modifications and moderate off-road use.

This forum likes to parrot that KDSS is problematic but I think data would suggest otherwise.

KDSS is a huge upgrade for body roll on-road. At higher speeds off-road (20mph+ on dirt roads, logging trails) it can be too stiff and feel rough but when you're at lower speeds KDSS loosens up and is amazing off-road.

Completely valid point. It seems to be said a lot on these forums without having too many examples of people actually having issues with KDSS. My stance is that because we do know that it is expensive to repair and that it is an optional component (and by that nature, not required), it does mean that one has to be prepared to fork out extra dough down the line should it fail. Sure it may never fail (and that would be awesome) but because it is not a required component when you purchase a 4Runner it is worth noting that it (like anything) may fail and is an expensive repair bill. I think that we just need to adjust our language around KDSS when talking about it "having problems"...

My rig is sitting at 102k miles and, to my knowledge as the third owner, there have been no issues thus far. :D

I absolutely love the ride and if I were to buy a brand new 4Runner tomorrow, I'd get KDSS no questions asked. It's fantastic off-road at low speeds and makes the street ride comfortable as hell.

I If you look at TRD Pro, it does not have KDSS option. Simply because, Toyota knows that Fox suspensions takes care of off-road needs and KDSS is redundant.

Also, if you plan to lift the suspension and have KDSS option, it appears that the recommendation is max lift of 2” in the front and 1” in the rear.

Some people who drive Off-road premium without KDSS complain that the suv rides like a boat and want to modify the suspension. Whether it is psychological or it is fact, I cannot confirm.

Bottom line if you plan on upgrading suspension system do not buy with KDSS option. You will have to live with ride capability till you make the modification.
incorrect
 
Strange, I never see either of those vehicles when I'm driving off the pavement here in the Southwest. :shrug:

Nice parking lot! :D J/K, which BB roads did they drive?

Perhaps I should have specified that I don't see those vehicles actually wheeling out on the trails. Then again, few 4Runners are driven in those conditions either! :lmao: And most of the places I go I hardly see anyone at all.

Also, I sometimes forget that not everyone has the same idea of what constitutes "wheeling." ;-)

We did all the trail at BB, including that stair thingy that i forgot the name of. It was easy tho.

And FYI, I have plenty of wheeling history. :D
 
KDSS is amazing, a lot of the times when you are getting to your off road spots you are going through windy mountain road. Having 0 roll, planted, even with a 3 inch lift feels super confident.. almost like a race car, which 4runner is not. Going down hill is even better.

Love my KDSS, i'm thinking about spacers in the back to return it to closer to normal, spacers in the front ruin clearance, not sure if the system is optimal with different heights..

It's like a smart disconnecting swaybar that's like a sports car swaybar beyuond 12 mph and nice and loose below.

KDSS is not the limiting factor here, it does connect with the back panhard bar if you have 'extended travel' I believe and there are solutions to this. 4wheeling is a game of inches, ironman does do spacers and a panhard bar with spacing for KDSS, I might consider it
