I have a 2020 4Runner Off Road Premium with KDSS. I wanted the option and I love it. KDSS is also available for Lexus GX460 and Toyota Land Cruiser ;both these vehicles are known for off-roading capability and reliability.

Because it is an additional system that is added to the 4Runner, people worry about its reliability and if you search the forums you will see that there are not many owners that have reported issues with KDSS So the system itself does not have systemic issues and it is pretty reliable.

Yes, if something goes wrong it does cost pretty penny to fix it ($3000 to $4000).

My personal opinion is if you plan to modify the vehicle and add high end suspension system like Icon Vehicle Dynamics or Kings system or fox racing to your suv then KDSS may not add much value.

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.

As for my plan, I may upgrade the suspension down the line but again may never do that. So for me KDSS works.


Good luck.
