Question about torsion bars

    I have 2 2007 GM 1 tons. One is a 4x4 pickup, the other is a 2wd dump truck. I was going to get them both lifted with the 2" leveling kit. I don't exactly know how to ask my question, but I will give it a shot. I took them to a friend that's a mechanic, and he told me that the torsion keys (stock) are the same thing as the keys that I got in the aftermarket kit. He cranked the torsion bars on the 4x4 truck, and got 2 1/8" out of them. The dumps are cranked but the plow mount still hits the ground.

    Now talking to the guy I bought the kit from, he says that those parts are different and made to take the extra load. He also says that if we put the aftermarket parts in, I will get an additional 2" of lift higher than the stock keys cranked up all the way. That is the exact opposite of what my friend says about them...

    My head is spinning with all this info. So figured I would come here and see if anyone knows the answer straight up. Any help is appreciated.

    The lift keys are clocked differently than the stock ones. So you should get more height out of them over the stock keys.

    ^Exactly the way I was told. I have the "green" keys (not in the truck yet) and from what I was told they are indexed differently so ou get more lift out of each turn vs a stock key. I guess I'll know myself soon enough.

    I thought the 2wd's had coil springs. I guess you learn something new everyday :)

    One thing to look for in a Tbar crank is that.YOU do not max them out bad things can and will. I have seen them time after time snap
    i found out the hard way it came through the floor and bent my passenger side seat ;-( and did you get it a alignment after the crank?

    Buy yourself a kidney belt, you'll need it. You sure the plow mount is installed correctly?
