[MENTION=27094]Danimal[/MENTION] actually I set aside all of the forum feedback and speculation. There are as many opinions for, as there are against kdss.
I called and spoke to 4 different service managers from different parts of the country and also spoke to 4 of their most knowledgeable technicians. I only got positive answers from 2 of the 8 people I spoke with based on my plans for a lift down the road. I figured if these guys are dealing with/working on kdss and tell me to forgo it, then I'll listen to them.
There is no right or wrong, just personal choice. That's why you can check the box or not!

Please show me the stats. You can't because there aren't any. Here's a fact for you, a tidbit of trivia as it is:
This forum has the highest concentration of KDSS equipped vehicles anywhere. Out of all these posts since I became a member five years ago, there have been three (3) KDSS failures and one of them was the guy disconnected the wrong line. So in reality two failures.
Most dealerships do not even have the tools required to work on KDSS. Why? Because A) Most dealerships don't sell many TE's, LC's and 470's and B) There is rarely ever a problem so buying tooling is silly for most.
My service manager and tech don't like working on flux capacitors either and they have about as much experience with them as they do KDSS. Pretty sure I can put those guys you spoke with in the same category.
You can of course get what you want. I have had both KDSS and non KDSS and liked them both for different reasons. The sole reason I posted is your post will get read by a lot of people and they should have the benefit of some facts as well.
There are many lifted KDSS equipped vehicles running around and it's no big deal unless you are going to go LT.
People have opinions on KDSS just like they have opinions on color choice.
The facts are (many Toyota videos to prove it on youtube)
1. KDSS will improve on road handling around curves
2. KDSS will firm up the ride on road
3. KDSS (under 12 mph) will offer substantially more articulation off road than a non KDSS equipped 4Runner.
4. KDSS has NOT been a component that fails prematurely. If it were we would hear about it first ad nauseum.
5. Unless you want to spend north of $10K this is the only suspension, aftermarket or OEM, that improves bot on and off road performance. Everything else just does one or the other.
Good luck and good choice of vehicles!
