I agree generally with what your saying. Sonoran Steel does have a 5th gen with KDSS that they experimented on so they have some idea. And Dobinson's has extensive experience with Land Cruisers with KDSS in Australia. So who knows? Both are right? Neither? Somewhere in the middle possibly.
EDIT: And Dobinson's USA has a 5th gen but without KDSS
That's not correct, David (the owner here) sold his non-KDSS model about 18 months ago. I own a 2014 Trail with KDSS with 3" front and 2" rear lift.
Long travel parts rear were developed and all test fitted here in Miami with David's old 2016 non-KDSS and the parts were never intended to be used on a KDSS model as they weren't tested and gone thru all the paces simply because they can't be used on it. This was known from prior knowledge about older KDSS systems already. Just what was written earlier, the KDSS system is limited because you can't add extended links to it like a regular sway bar setup.
The more lift that is added, the more the fixed mount side of the sway bar holds down that side of the vehicle (passenger side, right side). It's the same with a regular sway bar - the more you lift it, you should change to longer sway bar links to put it back in the correct operating position, or as close to it as possible. And if you don't extend the links, the sway bar will limit the wheel travel anyway when it gets as extended as it can.
OP, just go with a 3" front lift and 2" or 2.5" in the rear, and buy whatever fits your budget.
