YJ Going from Stock to 4 inch

I have a 94 YJ stock. I'm wanting to go with a 4 inch BDS Lift. This is my first jeep so I'm pretty green. What all should I expect to have to do. I read somewhere about lengthinig the front and rear driveshaft. Do I need to have that done as well or just a SYE?

Rear SYE and CV driveshaft. Front should be ok.
Lengthen brake lines.
If they are in good condition, they can be rerouted. (Thanks Anticanman)

Longer shocks to take advantage if all the wheel travel you will have.

First, please fill out your profile, as you'll get better responses.

Second, large lift = vibrations = SYE + rear driveshaft = larger tires = poor performance = regearing = replacing weak Dana 35 rear axle = tires rubbing on front springs = new wheels with more backspacing = more stress on the steering = steering upgrades = $$$$

I'd recommend a lot more research before dedicating yourself to a 4" lift.

How will you be using your Jeep? What tires do you want to run to need a 4" lift?

Where do I go to fill out my profile? Main use would be mudding. I have 31x12.50 km2s on pacer rims with some backspacing.
I don't rub on the fenders except when I hit a dip or pothole. I'm wanting to go with either genright or metalcloak fenders. Ideal tire size I want would be 35s. I have a set of 36x14.50 ground hawgs but they came off a cj and they would rub like crazy. I got that jeep from a friend and it was a rust bucket.

Money is not really an issue was just wondering what all I needed to consider
