I understand what keys are and how they function (for the most part). But was wondering what the objective is when replacing stock keys with ones from a ford or different Chevy? Is it the angle that cranks the torsion bars up without having to actually crank them, or?? If someone could explain the benefits or reason for replacing keys I would appreciate it. Thx

The keys are cut/indexed different, meaning that you will load the bars more with less cranking which in turn gives you the additional lift w/o maxing out the keys. Just keep in mind the more you crank the stiffer the ride and worse the angles of the cv axles are.

Exactly, although because you can crank more when you have different keys, doesn't always mean you should.
