Anything I should know about KDSS going in?

    Have a deposit down on a TRD ORP. Here in Canada all TRD Off Roads come with KDSS. Watched some videos on it and it seems incredible both on an off road but recently I'd read that there are problem with the system causing the truck to lean or outright leaking/failing.

    Anything I should know while it's still possible to change to an SR5?

    It rules!

    If you plan on keeping it close to stock heigh, you'll be fine. Higher lifts are fine as well but require some special parts.

    There is a small skid plate on the accumulator, on the driver's side frame rail. This needs to be cleaned out periodically as dirt can collect in there and eventually cause a failure. It's easy, just 2 bolts.

    I think the leaning issues are probably the result of people tampering with the system.

    Failures are few and far between. Don't worry about it. Enjoy your 4runner!!

    Don't have it but worked on a few trucks that did. It's a great system and wouldn't sweat potential issues, they aren't common. It's a great add.

    If you disable/bypass or remove KDSS in a few years, does it simply drive and feel just like an SR5 or OR?

    No. The sway bars are much stiffer, but also reliant on the hydraulic pistons to do their job.

    Is it a costly endeavor to “bypass” kdss sometime down the road if it breaks down and you don’t want to pay to have it fixed? Does it require buying a bunch of new parts?

    separate question... lets say you keep your 4Runner for 20 years and kdss breaks down on year 20. Will you still be able to find replacement parts? Or at that time are you better off going the bypass route?

    The best way to bypass it would be to delete the sway bars altogether. This wouldn't require buying anything. You would have increased body roll, though.

    I don't really know. I would hope Toyota would continue to make parts for it. But, if mine fails that far down the road I'll probably go the bypass route.

    Good that you have done your research on down side of KDSS.

    KDSS is a nice system. One of my buddies got his 4Runner with KDSS before I started 4Runners and like it till date. He loves the on road feeling and occasional camp ground / gravel roads. He hasn't lift his and join us with offroad drives no matter what we say. He just love on road feel driving fast on mountain roads. (I know its a 4Runner not a sports car but that's his way.)

    You will not get KDSS lean if you install a lift with a knowledgeable 4x4 shop.

    When you get KDSS leaks or failure as far as I can remember the part was $1500 or something here in Colorado (based on the post I see on my FB group). Or $4,256.00 as per one of the members in this forum.

    If you want to go with out KDSS going to SR5 is not the right direction. You can get TRD Offroad with out KDSS and TRD Pro.

    No you cannot remove KDSS after you get your TRD ORP with KDSS when it fails. It will show warnings on dash (from what I see online) unless you find a way to fix the sway bar in.

    When you want to lift search what kits goes well with the KDSS as it has some limitations. A good kit will solve the common problems of KDSS.

    When you are ready for sliders and skids buy the ones that support KDSS. Else it would be a pain, like trimming TRD Pro front skid for KDSS. Also look for KDSS skid plate as that is as a vulnerable place for trail damage. If you do snow driving make sure you clean properly to avoid corrosion problems with KDSS.

    Again KDSS is a good system made by a company called Kinetic Pvt Ldt in Australia (hence got the name Kinetic Dynamic Suspension System) loved by some owners including my buddy.

    Bigger A/T LT Tires, Slight Lift, Sliders, Rack, Lights, etc.
    It requires the use of different skid plates.
    It amps up the difficulty of some installs, such as sliders and suspension, due to the additional hardware.
    Sure, it is more complex thus more prone to failure. But it's a feature, so worth it if you desire it's benefits.

    OP stated in first post that all off-road 4runners come with kdss north of the border. Whether a pro is an option depends on how deep his pockets are.

    Genuinely didn't know that they did.

    Question, would that mean all non-Pro come with KDSS or do they put KDSS on the Pros up there too?

    *Edit* Nevermind i'm an idiot. I realize now you're saying offroad vs pro. I swear I read that as 4wd....ignore me. I'd delete my post but I would rather have it remain for the wall of shame.

    Sorry, I meant to say OR, but couldn't get my keyboard to work.

    That is news to me also. Toyotas in Canada have their own set of options and specs. I wouldn't think the Pros would have KDSS, though, or SR5s.
