    4R ORP should be here in a month or so... Opted to go with KDSS for a couple reasons A) its what was coming available and B) I will be using this as a daily driver 90+% of the time. However, I do have a few questions for those that have and understand KDSS:

    1) some folks say the KDSS softens below 12 MPH, and other say it only softens if you are in 4 Low and below 12mph. Can anyone confirm if its only in 4 Low or if it any time 2W, 4W.. etc. below 12 MPH?

    2) There will be times where I might spend the day or weekend on rougher logging trails and will probably average 30+ MPH. Has anyone installed Dr. KDSS switch to allow softening the ride above 12 MPH? If so, what has your experience been... is it worth it? When softened, is it like a 4Runner without KDSS, or is it even softer?

    any feedback/suggestions are greatly appreciated.. I can't wait to get my rig! :)

    As far as I can tell, the valves open below 12 miles per hour no matter what drive mode you are in.

    I don't personally have the doctor KDSS controller, but I hear good things about it.

    I don’t know exactly when it softens. Definitely at the lower mph. I will say having owned a few 5th gens as a daily driver the one with kdss is the smoothest on road. You don’t feel it roll as much with corners and turns. When you try to turn 90 degrees the thing cuts it like butter. This is true in both 4hi and 4 lo.

    My daughter in my wife’s rav says she feels like she falling when my wife takes corners hard. In the 4runner with kdss she doesn’t even notice.

    Hope that helps a little

    I have Dr. KDSS and it makes a big difference on dirt and washboard roads. Install is super easy and regret not getting it sooner.

    The gentleman I met with on Friday to do the tune on my 4R has the Dr. KDSS switch, and he loves it. He also said on long highway drives with no major curves or turns it rides much better with the KDSS turned off. FWIW

    Installation is easy. The supplied instructions are very detailed. I put my switch in the second spot from the left by my left knee.

    My DR KDSS order is on the way (KDSS switch, harness, front sway bar stuff for lift). Really curious about non hwy driving, especially since my ride is a firmer than stock after lift.

    Interesting. I don’t know if the DrKDSS switch will help in your case as much as it would with a softer stock suspension.
