thank you Stefan for the feedback on such an install. With KDSS option in place, the front two suspension height needs to be identical for the 4R to be levelled (side to side) correctly.

i have been driving a 2019 TRD Pro VooDoo for 9 months and love the Ride quality. trading it in for a 2020 TRD-Off-Road Premium with KDSS. I decided to buy a Toyota PRO Fox suspension kit with all four suspensions, AND one separate FRONT DRIVER Side PRO Fox suspension. The idea is to make the front two suspensions identical by using the separately bought Driver side suspension on the Passenger side. this means that I will end up with an unused passenger side new suspension from the kit. I checked the 19 pro and the fitment won't be an issue.

any feedback? the alternative is to use top spacers to match the over all height on the passenger side. more trial/error approach.

I also welcome recommendation for alternative setup that will give me (1) plush ride just like the Factory Fox Pro setup and (2) retains the front height (won't mind if it levels front to back but definitely not looking for a 2 or 3 inch lift on all sides - meaning the back needs to remain at stock height as it barely fits in my garage at work.

appreciate any feedback.

I'd be interested to see how this goes and may consider doing it myself, but from what I've read, the price of the toyota/fox parts is equal or more than better quality after market parts. Please take photos before/after.

Why not just buy a full Fox 2.5 kit? instead of a TRD kit that's going to have markup and also an extra front component?

sure.

The back will remain at stock height unless you replace the springs. The fox 2.5 should be able to be adjusted down to essentially 0 if you wanted. However the spring rates and shock damping maybe stiffer than the pro version. I’d want the non Toyota ones for the adjustability.

The pro fox 2.5 is not height adjustable.

Maybe he’s getting a great deal on the trd pro fox suspension. A guy was selling his pro fox for $350.

Correct. I bought a new condition TRD Fox set for $1200 with less than 3K miles on them. a fellow forum member just told me that if I use 1inch cornfed (front passenger) and 1/3 inch cornfed spaces (rear passenger) side on top of the fox then the truck will be fully level on all sides... no KDSS lean and the TRD fox will work. this is when i though of buying a spare driver side Pro-Fox (haven't bought it yet) and installing it on the passenger side... just a theory to potentially avoid the spacers.

thanks i also checked the Fox2.5 from Fox and they are adjustable (depending o the model). would have followed that path if i didn't buy the ProFox set already.

Why are you trading in a 9 month old pro?

So I'm not sure that I am reading/understanding everything correctly. Do you already have the new truck? And does it have the same amount of KDSS lean as the person you're buying the suspension kit from?
Reason I ask is it seems every 4Runner is different when it comes to KDSS, some have no lean at all (Mine for example) and some have quite a bit.

To me it would seem easier to use a screw type adjustable coil over to adjust the front to get it dialed in correctly and a spacer to adjust the rear. This would allow you to dial it in as close to where you want it as possible. Also remember to get the rear dialed in first then adjust the front.
