    It’s a linked stabilizer bar system that utilizes hydraulics to minimize body roll on road and increase articulation offroad.

    Here are some videos on it.

    Pro’s.
    Better on road manners
    Better articulation off road
    Can be removed without damage to other systems. Fully independent mechanical sustem.

    Cons.
    Expensive to repair if damaged

    I say it is something you want for most people.

    Especially if you are going to do more pavement pounding. Minimal off roading for me so no comment yet. But on pavement you can feel the difference.

    So, in the end I shouldnt NOT want it... if the particular vehicle we are looking at has our desired options and has kdss, thats fine, no problem?

    I’d say so. I’m not sure what your intended use of the TRD OR is but I’m not afraid to take it and hit the trails. West coast has its cornucopia of options from rock crawling to high speed runs through the desert.

    I had it on my 2005, never had a problem when I traded it in with 210,000 miles. Don’t have it in my 2019 and I’m glad because IF it gets damaged you will probably have to replace the entire system. In the case of a car accident it may total a perfectly good truck, later down the road.

    I think you had XREAS. KDSS wasn’t an option on 4R’s until 2010.

    You are correct, sorry, there was taco between my 4buggys and I forgot!
    Is it the concept though?

    XREAS is where the shocks are linked together. KDSS is the system that connects the front and rear sway bars

    I dunno. I test drove one with and one without on the same road with some very crummy potholes etc. I didn't notice a difference so opted without for ease of lifting down the road(from what I read)

    LOL not much harder to lift with KDSS if going with the typical 3" or less.

    And if you can't feel it I dunno what to say.

    Just read through these forums options are limited to how you can level or lift. If that's wrong I only know what I read, mostly on that crowded forum.
    As far as feel, with test driving and now 400 miles with mine, on road crappy Chicago roads are just fine without kdss. Maybe my old arse just couldn't tell the difference..chit breaks the older one gets:turtleride:

    My “off-roading”, if you can even call it that, is camping, driving on the beach, launching a boat, etc. I don’t plan to lift 3”+ or rock crawl. I test drive both and noticed a difference driven back to back, but probably wouldn’t have if I drove them a week apart. In the end I opted for the KDSS as I thought it made more sense for me as 90%+ of my driving will be on road.

    When driving on the street you can tell in the corners there is less lean. I have a 3 inch lift no problem and I off road all the time it works great. It is not my daily driver.

    Do what I did when I test drove one with and without.

    Find a empty parking lot do 40 mph and go from side to side and some 20/30 mph circles you will be convinced to get one with it!

    I've read a lot. I also have a TRD OR w/KDSS lifted. I don't think its that limited there is a shit tons manufacturers. Now if you are talking LT and crossmember thata a different story but that also doesn't apply to the majority.

    KDSS would not help with potholes. On road it reduces body lean by using thicker sway bars.

    To the OP- as mentioned, test drive vehicles with and without if you can. Also think about what you intend to do with the truck down the road.

    If you plan on doing massive lift, and hardcore off-roading, you might not want it. If you plan on mild lift, or no lift, you might like it.

    Enjoy whichever you decide to buy!

    It’s a little bit more than just the sway bars. The front and rear hydraulic cylinders, accumulators do the work and the thinker stabilizer bars support the addictions force applied to them. On road the hydraulic action works against itself and reduces the ability of the cylinders to compress and cause body roll. Off road, the hydraulics isn’t working against itself and allows for more wheel articulation and stability in the vehicle.

    I know all of that. I was just saying that the biggest difference for on-road driving is the reduced lean due to the larger sway bars. And that it wouldn't affect the handling over potholes. At least not at high speed.

    But, your post explains it a lot better. And I also would not have bought one without it.

    Love mine with KDSS, the truck climb rocks with no issues. It's not a dedicated rock crawler but even with KDSS it'll hold it own very well. :thumbsup:

    Love mine without KDSS. When researching this vehicle before buying I decided against it. No regrets.

    I have KDSS on my T4R. I absolutely love it. Its my daily drive and my storm chasing truck in the winter. But since Ive been driving it around I am clearly going to take this beauty off road now.

    But as someone who drove sports cars before it felt a bit better driving on the pavement with the KDSS. not like I am going to drive this truck like I would a Mini Cooper but I felt the difference and that is why I opted for it. Also the truck I stole from the dealership (37K ORP :) ) had that option on it and i didnt have a choice lol.
