More About Flip Kits, C-Notches
The first thing to get off the table regarding “flip kits” is nothing is actually flipped! Simply put a flip kit moves the axle from beneath the leaf spring to on top of the leaf spring.
Usually a six inch drop of any kind causes you to need to “notch” the frame to gain travel. You actually cut relief (notch) in the frame directly above the axle and install a frame support bracket.
