im planning the next step in my jeep mods and it will be more lift. right now i have 2 inch spacers and no tc lowering kit with no vibes at all. i am looking at two kits,
Rustys 3 Inch:

and
Cage 4 Inch

I like the Cage kit better for a couple reasons...progressive rate coil springs, nitrogen shocks, and more clearance. The cost between these 2 kits is not really an issue.
My question is, with the Cage lift, will i have any driveline vibes? It does come with a tc lowering kit and i am pretty sure that the rear driveshaft on a 2.5L is a bit longer to start than the 4.0L. Also, if it does have vibes, at what speed will it kick in(i cant go any faster than 65ish with the 4 banger). and last question, if i would have a vibe with the 4 incher, would a motor mount lift help that. I know the best answer is sye and longer driveshaft, but that would send me over budget with either kit.
