I have a 2014 Sahara and I love it. At some point I'm going to get it lifted, probably 2.5inch and put on 33s. Maybe bigger, but it is my daily driver so I want to keep it reasonable.
I've done quite a bit of reading and watched a ton of vids on the topic.
It is my understanding that the lift will change the geometry of the suspension and that can cause the driveline to vibrate more so than it would otherwise and this can lead to the driveline wearing out faster.
I've heard about slip-yoke-eliminators, transfer case drops and installing a different drive-shaft (tom woods) that is more suited to the vehicle that has a lift.
Some say just go with the lift and figure out the driveline when it starts to fail, such as when you notice grease slinging from the boot. Perhaps it won't fail for a few years if you are lucky I've heard.
I'm wondering if it makes sense to go ahead and make the needed driveline mods on my JK before the fact so that I don't have to worry so much about the driveline failing prematurely.
I'm the kind of person that would rather get it taken care of up front. But I wanted to get some ideas from the experts.
Looking for those with some experience to comment on what they would do with a 2014 Sahara given the concerns and thoughts I've just described. Go with the lift and worry about the driveline later? Or take care of it up front? And which lift kit and driveline mods make the most sense in this case?
At 2.5" of lift you will probably be ok however if memory serves the limit for the stock drive shafts is about 3" so you are close. I unfortunately don't know a lot about the 3.6 JKs but your best bet may be to call up Just Jeeps, CT Motorsports or one of the other sponsors and talk to them about your plans and see what they recommend. These guys work on this stuff day in and day out and know what issues they tend to run into.
