Wildtrack Perch Collar Lift Question

[jasongrim2016]

I am considering installing RPG Perch Collars on my 2023 Wildtrack, 3 inch collars in the front, 2.25 in the rear. My question is do I need to upgrade the Upper Control Arms. Is it necessary, overkill or a good idea.

FWIW, IMO, anything over 2" should upgrade the UCAs to be able to comfortably align post lift.
