Frankenlift uses OME springs
so
Frankenlift come preassembled so somewhat easier to install and will give you a little more height
OME springs and other little things ( top plate from JBA and clevis lift) give you almost as much lift for a cheaper price)
I have installed both on several KJs and ran versions of both on mine and after breakin not much overall difference in ride or handeling
so
6 of one half dozen of the other
