still necessary?

If i install a 3.5 inch suspension lift, will a CV shaft and SYE still be needed, or is that only once you hit 4 inches of lift? Thanks in advance.

its different for every jeep, but usually around three inches of lift people start getting driveline vibrations. Some of those have been solved by transfer case drops and motor mount lifts. An sye and cv drive shaft will make sure theres no problem though.

Possibly it will be needed. You will need to put the lift on and see if it will need it or not.

I had a slight vibration even after a 2.25" Budget boost. A motor mount lift cured the problem. I'm pretty sure you will need it, or a pretty big transfer case mount drop (which kind of defetes the purpose of lifting it). But, like stated above, every Jeep is different. Don't forget, you will also need rear upper adj. control arms with your SYE and driveshaft.
