You really don't get much more ground clearance from driveline components with say a 35" tire. The stock equivalent (33") might have about an inch less clearance over the larger 35'. Think about the drop sub frame in the front for most IFS lifts, you lower some frame components to make suspension and cv axles happy, decreasing ground clearance, the tires will give you some clearance, but 2 inches in diameter is peanuts for actual clearance...more like 1 inch. The pumpkin in the back stays near the same height with larger 35's as well. A mild 6" lift might give you an advantage for high center clearance, but thats about it. In my opinion, any lift for an IFS truck is near pointless, but can make a truck look good...if built right without gaudy wheels and ridiculous tires. In my area of south carlonia, truck owners measure height and ground clearance in their perceived diick inches, not actual inches anyway.
A lift, if done neatly will make your truck look good, but thats about it. I did the lift thing many years ago, and will never do it again...
1. a SAS is not available for the titan...at least that I know of, without an expensive custom job.
2. Handling, parking, driving, acceleration, overtaking mustangs, racing and many other wants go out the window. (for a daily driver)
3. big tires that accompany lifts usually have agressive tread patterns which get annoying quick. small tires with big lift leaves a huge gap between the tire and the wheel well, making your truck look like a 5500 dodge or something...no street cred. lol
