Yes. As close to 0* as possible. I'm not sure about the total lift the CV on these trucks can handle. Someone else might know. I ran into an issue on a different truck where the tabs on the CV joint were touching. Basically the CV was at its maximum angle, and that was only a 5" lift. Angling the t-case actually lowers it in the wrong direction resulting in more CV angle but lowering does relieve the stress on the rear u-joints. The best way to lower anything is to lower the u-joint/CV joint location itself, like on a monster truck. But I dont remember any lift companies offering that item. And you say why would a company make a lift that didnt work or work well? Easy, because of money. And really, how many people actually care if they have a little (or bad) vibration while cruising or if their truck is totally off road capable. I would say, for most people, the critical items of lifted trucks are how big are my tires, how pretty are my new aftermarket rims, and is everyone looking at me in my bad four wheel drive as I hum down the street. Am I right or am I right. These companies know who is buying their products and for that reason you get what you pay for. Want a truck that can truely get off the road and get you back on with little to no problems? Well you are going to have to spend some real money. It took me a long time messing with cheap garbage to finally realize that working realiabilty=$$$. And please no one be insulted by my point of view here. Its just obvious observations. To make my point even more clear, I believe someone just posted that they have a driveshaft that is held together by 1/2"! If that bugger comes apart at anything more than parked speed it will do some high dollar damage. Why do I say that? Because I had a front driveshaft CV break on me while driving and before I could stop the whipping action of it destroyed my exhaust, tranny, and bent the frame. Hard lesson learned there. All I can say is good thing it broke at the CV instead of the pumpkin since it might have po-goed the truck or shoved the driveshaft through the floor board. There is companies that make good off road product but they are expensive. Sorry for going on, too.

 

Even though it looks as though my front shaft is together by only a 1/2" or so. I have tested it and found that it does not slide out at all. I have twisted the front to rear axles and checked to see if it would come apart, nope. I have plowed all season with it hitting strange angles, nope. So I will agree, it doesn't look the safest but it is and will probably do something different in the summer. But for now being the mid-winter and I know it won't come apart, it is working just fine for me. Though I did look this past weekend and pinion angle is off due to shim up front and my shaft tabs are slightly hitting the yokes. But I only use 4wd when plowing slowly and try not to use it while driving fast. I need to fix yokes this summer.
