I have Bilstein 5100’s on my 2018 KR set at max height, and the truck rides like stock. Plan on getting them for my 2021 Plat.
I posted this same question, one answer I got was that a 2021 had the 2015-2020 fox 2.0 coilovers installed with no issues.
Do we know if the shocks from the previous generation will fit the 2021? Was looking to order the Bilstein B8 leveling shock, really liked them on my 2018.
