Getting ready to install the Bilstein 6112/5100’s on my 23’ GX460. Planning on a 2.5” lift for the front and 2” for the rear. My question is before getting ready to do the installation are these parts required or will I be able to get away with them and just install the shocks with only UCA. DrKDSS rear track bar correction kit, DrKDSS front sway bar adapter, Front and Rear KDSS spacers. As for wheels I haven’t decided yet. Thank you.
