Is it possible to add TRD PRO suspension?

[SOLRUS]

I don't plan to change shocks for at least 10 years , I do mostly highway, 5160/6100 will give a room to add front bumper and roof rack, that's all I need

I don't know how many are aware but Toyota is ditching Bilstein for the TRD component and is contracting with FOX.

It might be worth the wait to see what they are going to come up with.

For those who went with a level kit up front and if you still have your stock perch I'd like to buy a pair. I recently bought the trdpro suspension with the 1inch leveling perch already installed. I'd like to have a pair of the stocks just incase j change my mind in the height.

Im talking about this part. The photo shows the aftermarket leveling kit which is thicker than stock.

Hi , I'll try . As far as the ground clearance in Toyotas own literature published you have less ground clearance due to the sway bar bracket design on the rear axle and also the bracket design on the front lower control arm. Also the hoses and frame mounted oil canisters tend to be vulnerable. The system is also heavy for obvious reasons. The reason that Toyota does not offer a lift with KDSS and it is not advised to lift a vehicle with is the same reason it's not advisable to lift a truck with stock shocks. The KDSS cylinders have a predetermined stroke in and out when you lift the vehicle you move that stroke near the top so you have less down travel it's like putting on a lift kit or a long travel kit but leaving the stock shocks. You will hear the KDSS cylinders bottom and top out like a shock would when you reach their limits. And Toyotas design is for the shock to limit down travel not the KDSS cylinders so there's another durability issue. Another problem and the reason that Toyota did not offer it on the TRD pro is heat the increased stroke generates heat which equals fade which equals the sway bars losing their effectiveness in high-speed off Road type desert , The opposite of what you want on the TRD pro. KDSS is a good system and it has its place if left stock it works great and does what it's intended to do , allow a vehicle to have better Street manners and still go off road that's why it's on the Lexus , and not the FJ , it's not primarily designed for off-road it's more a design for a compromise to go on road as the sway bars are much larger.
Note This is only for you asking these questions I have been flamed for this many times. I hope this explanation helps in someway.

I know that this pretty old but i think I should give a different experience. I recently lifted (BP51) my 2016 GX equipped with Kdss. Before we started the lift installation there are two little valves under the driver floor that allow the piston to travel freely. After the lift is installed and the car is back on the wheels, shake the car side to side , make sure there is no lean left to right, then valves are been closed. Based on ARB explanation, what I consider a pretty reputable company, by doing this the piston is returned back in the middle of the stroke. The only way the piston would hit top or bottom is if you increase the wheel travel. As long the travel is the same, the piston can be reset. In fact, most of the aftermarket lift kits makes you loose some of the travel. You can read a little bit more at ARB USA. I am not aware if the Long Travel kits are based on increasing the angle they are travel or simply by increasing the length of the A arms and drive shaft.
When about the reliability of the KDSS system ,, I am pretty sure they would not race the 4Runner equipped with it , if they where not sure it can handle. Is this something else to worry ?? probably yes but I am pretty sure that will last the life of the truck.
That is my experience with KDSS. Please don't take this as criticism. Just different opinion.
