Not trying to pick a bone with you Straycat, at all. I respect you a ton. I just want it to be clear.... The aftermarket T-bar keys do exactly what the stock keys do, just more of it. The only difference between stock and aftermarket keys is; the aftermarket keys allow you to crank the bars even further. The only way to get lift without brackets is to turn the bars. That's all the aftermarket keys do. Either way it's going to do the same damage to your CV's. The Aftermarket keys aren't going to do less damage then the stock, if anything they'll do more.
Stock keys: Up to 2" of lift
Aftermarket keys: Up to 3 1/2" of lift..
If I recall correctly, 12-13 degrees of angle is safe on your CV shaft. Past that is where you start pushing it pretty good....
Someone correct me if I'm wrong on that. It's been a few years...
