PRO Fox suspension install on 2020 TRD-Off-Road /w KDSS
i am currently driving a 2019 VooDoo Pro and absolutely love the ride of the Fox. Casual trails in the cottage season and mostly 90% city driving in Canada - road have a ton of pot holes and never maintained. Anyways, I am upgrading to 2020 TRD-Off-Road-Premium with KDSS and going to install TRD-Fox set that I just bought a few days back. some concerns based on some other users' feedback can be found in my thread - that was because of KDSS. If you do not have KDSS then you will most likely be fine. I am going to find out when I install them. I am determined to make them work. all the best.
BTW, I have owned a 1999 Limited and a 2011 Trail with KDSS before the 2019 Pro. Also wife drives a 2010 Limited (with X-RES) so I can comfortably say that the Fox Ride is the best. Do not mix it up from KDSS as the function of the KDSS is completely different than the suspension. many people mix the two topics - they are not interchangable.
