I am swapping my front one springs out for the Toytec 620lb springs. I have tundra 5100's. I know these are 3" lift springs. My old springs were only 2.5 so that's why it's on the second perch. Do I need to keep the perch on the strut on the second one still? I do have a CBI bumper and winch. I am swapping springs to bring my front end up some.
