Pre key vs bar crank

Pre key vs bar crank
I understand the difference between the two, but how does cranking the torsion bars put more wear on the front end than doing the pre key mod on my 2010? The front end doesn't know how it's lifted an inch or two, so what causes the extra stress? In my head, they do the exact same thing to the front end. I'm not looking to lift it big, just level it out, so the only advantage the pre key mod would offer me is the ability to crank it even more in the future, right?

Cranking your bars adds more stress to the front by throwing everything out of alignment. It isn't as noticeable when just changing to the 07 prior keys because then your just going to stock height for those then people usually add larger tires because they fit which also causes wear and tear on the front end. Its when you crank them further than the 07 stock settings. I have 2" lift keys in mine and I wore out the upper ball joints because i didn't get the camber adjusted and it also messed up a set of tires. So it basically puts more strain on everything by going over the stock 07 height

I had this question when I was about to buy the Leveling kit from "Ready lift" with includes a forged keys. But after analyzing it is just about the same.
In that website they assure that you wont overtorque your keys, but this doesn´t apply to the Torsion Bars, I mean, the Torsion bars and the rest of the front suspension will be equally affected if you crank the OEM keys or just install the aftermarket ones.
In both scenarios the Torsion bars receives an overtorque. A faster wear on this bars and ball joints will be the result, first one caused by the extra torsion, and the second one by working in a differente range /position than designed.
Anyway I have mine lifted 1" by cranked keys and I think this minor change wont affect to much.
Hope can help.

Your truck already has the "pre-keys". It's the 08+ trucks that don't. You can get a couple of inches of lift on yours with your stock keys. Leveling it out with the back should be no more than a 2" crank, but you will notice the ride getting a little stiffer, and so will your suspension components.
And for the record, on an 08+ truck, cranking your bars 2" or swapping out to the older keys does the exact same thing to the suspension. The end result of either is that the torsion bars are turned up to increase the ride height. The difference is that you will still a good range of adjustment with the older keys.
